Industrial production of laccase Essay Example | Topics and Well Written Essays - 1000 words

Industrial production of laccase - Essay Example This enzyme is mostly seen in higher plants and fungi. In plants, laccases can be seen in trees, turnips, cabbage, asparagus, beets, apples, pears, potatoes and other vegetables. It is also detected in other plant species like mango, mung bean, prune, syncamore, peach, pine and lacquer. It is also evident among insects likeCalliphora,Diploptera,Drosophelia, Sarchophaga,Rhodnius and Papilio.However, wood rotting fungi are the most common producers of Laccase. Even though laccase is present in plants, insects and fungi it’s activity is limited in bacteria like Marinomonas meditteranea, Azospirillium lipoferum. Laccase is an enzyme with less saccharide compounds in bacteria and fungi compared to plants. The studied that conducted are on extracellular proteins although intracellular proteins are found in several insects and fungi. The purified form of laccase exhibits a blue appearance. The production of laccase from fungi is practiced for industrial use. As per Mayer( 2002, pg 55 1-65)â€Å"Laccases are involved in fungal virulence and possibly in lignification in higher plants† History and Development The laccase enzyme was discovered in Japanese tree Rhus Vernicifera more than one century ago. For many years it was believed that only the ligninolytic system of some white rot fungi could aid in production of lacasse. However, it was Bourbonnais andPaice who found that laccase can catalyze the oxidation of non – phenolic benzylalchohols with the aid of redox mediator. This led to the discovery that laccase mediator system can degrade effectively residual lignin. Because of its extensive reaction capabilities and broad usage in biotechnology it was further studied. In most fungi, lacasse is produced at low level which is not enough for commercial purpose.Lacasse are promising enzymes which has a conventional usage in industries like textile, pulp and paper, pharmaceuticals and nanobiotechnology. Lacasse is generally produced by fungi grown on ba sal media at low concentration. As per Gedikli(2010,pg.9 -16) â€Å"Lacasse activity depends on the type of fungal strain used, growth conditions employed, the presence and the absence of inducers, incubation time, nature and composition of culture medium and genetic manipulation†.In order to obtain higher concentration various supplements need to be added like metal ions. White rot fungi is known to have diverse response to inducers in lacasse activity. If inducers are added it can enhance the concentration of lacasse.The lacasse production is highly depended on the cultivation conditions of the fungi strains. The lacasse is primarily produced in industries by submerged cultivation method. However, the excessive growth of mycelium is one of the disadvantages of this method as it hampers the production yield due to mass transfer and metabolic limitation. But this situation can be controlled by the immobilization of cells. Solid state fermentation is also a method to produce l accase. The laccase enzyme is extracellular and secreted in to a medium through filamentous fungi. The secondary metabolism of different fungi generally produces lacasse. The lacasse production is influenced by different factors like type of cultivation, concentration of

Managing Change in an organisation Coursework Example | Topics and Well Written Essays - 2000 words

Managing Change in an organisation - Coursework Example The case indicates the existence of a large internet provision company that has employed a large number of employees. In addition, it also possesses small sales stores in two other cities. With this, it is expected that the business activities should make it possible for the organization to attain its goals and objectives in an easier manner. However, it is not possible since the culture within the organization does not provide the appropriate environment for the staff members to work together as a team and achieve the organizational goal.The cultured within the organization is so relaxed to the extent that it does not allow the organization to provide satisfactory services to its customers. This is what creates the need to change and manage the different aspects so as to ensure that the quality of services provided by the organization make it possible to meet the organizational goals and objectives. In this case, the principle problem to be addressed is the culture of the organizati on in terms of management of people and the tasks within in order to maximize the services that are provided to the customers and therefore, the returns that are produced by the organization.One of the major issues being faced by this organization is the fact that the culture within it was very relaxed. This is in the sense that the employees do not have a specific dress code, they are merely employed as friends and not in an official way that is based on the merits and demerits of the job at hand.

UK Economic Indicators Assignment Example | Topics and Well Written Essays - 4000 words

UK Economic Indicators - Assignment Example Typically, macroeconomic indicators are divided into several types according to their significance for exchange movements, as it affects the volatility of the market at the time of publication index. The overview of macroeconomic indicators Macroeconomic indicators cover economic development, point to economic growth or decline. Therefore we can say with certainty that the output of major data can lead to significant and lasting movements in exchange rates. These are important data: Nonfarm Payrolls, GDP, Industrial Production, CPI, PPI and other macroeconomic indicators. There is a calendar of economic indicators and the most important events in the life of the individual states (with specific dates or approximate time of their release). These events market is ready. Emerging expectations and forecasts of the value of an indicator can be and how it can be interpreted. The output data can lead to sharp fluctuations in exchange rates. Depending on how market participants apostrophe an d interprets a particular indicator, the rate can go as one and the other side. This movement can lead to a strengthening of an existing trend of course, its correction or the beginning of a new trend. Or that the outcome depends on several factors: market conditions, economic status of the host countries examined rates, preliminary expectations and sentiment, and, finally, the value of a specific indicator. The indicator of average earnings growth is calculated by taking into account earnings growth over the past three months (taking into account all payments that were actually made and not "accrued"). This is a good indicator of future inflation, as rising wages, if it is not offset by productivity growth is the cause of rising prices. Average earnings growth is one of the defining indicators, according to which the Bank of England determines the level of interest rates. This indicator has a significant impact on the market. The indicator of producer output prices (PPI output) is defined as a change in the level of wholesale prices of goods in the industry. It is a strong indicator of inflation that reflects the inflationary pressures on the economy by the manufacturers (the increase of prices in "output" may not affect the inflation index, as it can reduce the costs in the trade). The price of food, alcohol, tobacco and fuel (prices for these products is very variable) are not taken into account. The indicator of producer input prices (PPI input) is defined as the change in the price level for parts and semifinished products in the industry (the rise in prices may not be reflected in the inflation index, as it can reduce the costs in the manufacturing process). The indicator of retail price index determines the change in the price level in the basket of consumer goods. The indicator of inflation is the Retail Prices Index, excluding the interest payments on loans to purchase real estate (RPI-X). The retail price index is calculated by a single formula. If t he growth of rate exceeds the planned value of the index, usually the Bank of England raises interest rates. The indicator of CBI industrial trends overviews (in the form of numbers) the business sentiment of businessmen about the state of the manufacturing sector. The review has no direct connection with the real prospect of economic development. The indicator of CBI distributive trades overviews (in the form of numbers) the business sentiment regarding business trading areas. Review has no direc

The rise and Fall of American Economics Term Paper

The rise and Fall of American Economics - Term Paper Example Considering that macroeconomics characteristically focuses on a nation’s economic performance including the manner in which the nation’s economy interacts with other economies globally, it is worth noting that the economy of the United States is not only the largest but also the most complex in the world history, with 87,600 separate government jurisdictions, approximately a hundred and fifteen million households, and thirty million profit organizations/businesses. The U.S. economy is therefore comprised of millions of decision makers who though acting with some autonomy, are all linked with the entire economy. The economy is dynamic – keeps continually renewing itself with new businesses, customers, foreign competitors, households and public official groups among others. Currency circulates throughout the U.S. economy, which facilitates the exchange of products as well as resources among the individual economic units – it is constantly in a circular flow (McEachern, 2008). Historically, just like other industrial market economies, the economy of the United States has gone through sporadic contraction and expansion periods. The rise and fall of the economy refer to the economic fluctuations relative to the economy’s long term growth tendency.... The rise and fall of the economy refer to the economic fluctuations relative to the economy’s long term growth tendency. These variations/business cycles vary in intensity and length, although some elements are universal to all. Usually, the fluctuations involve the whole nation and frequently several other world economies. Additionally, the fluctuations affect almost every economic activity dimension – not just employment and production (Hirschey, 2009). McEachern (2008) notes that the simplest way of comprehending the business cycle is by exploring its elements. He explains that in the 1920s and 1930s, the national Bureau of Economic research director carried out an analysis of business cycles and identified two phases of the economy namely â€Å"contractions† and â€Å"expansions.† He elucidated that the output of the economy declines during a contraction while it increases during an expansion. Prior to WWII, a contraction occurred – this was as severe as to be termed a depression. A depression is a sharp decline in the entire production of the nation going for over a year and accompanied by high rates of unemployment. When a contraction is milder, it is reffered to as a recession – characterized by a reduction in overall output over a period of at least six months or two consecutive quarters. Unlike prior to the world war II when the United States experienced both depressions and recessions, in the period after and until the year 2008, there have not been depressions; only recessions, which is an indication of an improved economy. The quarter-century after World War II appears more like a golden age for the economy of

Reflective Thinking. Easy Jet on airline markets. PESTEL And SWOT Essay

Reflective Thinking. Easy Jet on airline markets. PESTEL And SWOT Analysis - Essay Example This step involves revisiting experiences and knowledge with respect to the topic in question and why and how one performs the task. It involves examination of values, beliefs, assumptions and attitudes. Reflective thinking helps clarify and recognise the connection between what one knows and learns (TLC, 2008). Figure 1: The Thinking Process (Source: TLC, 2008) The reflective report prepared aims to demonstrate my knowledge derived from the projects on Easy Jet and various sections like business environment, PESTEL, Porters Five Forces and other relevant theories which were used in the project. Findings from the Report Based on the project made on Easy Jet, I have found that Easy Jet is regarded as a low-cost operator and is performing well in Europe. It operates internationally and also in a domestic airline market. It aims to becomes the best and the cheapest airline operator in the world. The airline faces tough challenges from its competitors such as Ryanair, British Airlines an d others. One great impact which I have noticed is that with the coming up of low-cost airlines, travellers prefer to travel by air rather than by bus, train or other means of transport. However, it should also be noted that along with low prices the airline should also be able to provide a level of comfort for the passengers so that the passengers feel comfortable while travelling, and I think the airline will be able to retain its customers in a positive way. I have analysed the business environment with the help of tools like PESTEL analysis, SWOT Analysis, Porters Five Forces along with operational management, supply chain and micro economic factors. In the process of using Porter’s Five Forces – a tool taking into consideration five important forces and helping determine the level of attractiveness in a particular industry – it was learned that the airline industry cannot be considered to be attractive because of the many unfavourable economic conditions pr evailing in the airline industry. The cost of entering is high and maintenance of airline is also a costly affair (on the other hand, it reduces the threat from new entrants in the airline industry). The bargaining power of buyers has the potential to result in a threat because of the competitive price offered by other airlines. It has also been seen that a threat of substitute is pretty high, as with the existence of other transport means such as buses, trains, cars, etc, passengers prefer to travel rather than to spend almost the same or a slightly higher amount on more expensive means of transport. Reflective Statement While conducting the analysis, I have learned that the above tools form an integral part of any analysis and have helped me understand the impact of various factors on the organisation. The first framework which I have used to analyse the airline industry is PESTEL analysis; this is because PESTEL takes into account the industry as a whole and analyzes political fa ctors which might impact the industry, as well as economic, social, technological, environmental and, lastly, legal factors. Why PESTEL Analysis? PESTEL gives an overview of the industry and is necessary to conduct, as it helps organisation to take the advantage of the opportunities; it also has the potential to minimise the threats. In the process of conducting the project, I have understood that PESTEL analysis can be carried out in relation to any form of business and industry, and it is one of the most important tools through which the companies evaluate the external environment and make necessary changes to fit the competitive environment and to survive in it.

Airplane Crash Survival Assignment Example | Topics and Well Written Essays - 750 words

Airplane Crash Survival - Assignment Example This research will begin with the list of item collected. The pilot who was among the survivors instructed how to gather all items that had been left after the crush, and listed them down in the order of importance. The items were listed as follows; newspaper for starting fire, liquid lighter for lighting fire, small axe for cutting woods, can of coconut oil and large chocolate bars, which would provide food, a map and compass for direction, extra shirts and pants for the extreme weather. Additionally, large heavy-duty canvas for making a tent, red lipstick for marking the map, lastly the batteries and toothpaste for freshening. After the survival of the plane crush, the pilot stressed that they had to work as team in order to survive in the jungle. Their Primary objective was to survive the extremely cold and snowing weather whilst trying to find help. The author was tasked with the responsibility of fetching woods and setting up fire, while his teammates were tasked with erecting a tent using the large piece of canvas. The following day, their focus shifted to finding help. According to the map that they collected after plane crush, the nearest town was 20 km away. The team tasked the author with role of reading the map and the compass in locating the nearest town since he had some background knowledge in surveying and navigation, while his teammates cleared the bushy forest for their passage.... Concerning leadership, the activity exhibited the fundamental role of leadership in an organization. The presence of a leader, who was the pilot, ensured effective delegation of tasks and provision of guidance in attaining the set objective. The STAR team model The performance of the pilot, the team leader together with the activities of the team members can further be explained with the STAR team model. According to Maginn, the STAR team model seeks to identify what a team leader and team need to focus on. The model combines various teamwork theories such as those proposed in the Tuckman’s model, leadership theories, and theories relating to the surrounding of the team and teamwork (pg 155- 160). The STAR team model focuses on an individual’s strength with the objective to enable the individual attain his/her goals leading to happiness. Thus, the application of the model ensures teamwork, which results to flourishing of individual as they use and develop their strength s. In our activity, the pilot assigned tasks to each survivor based on his or her strengths, which ensured attainment of the set goal. The model also explained that coming together of individual strengths and teamwork creates natural flow of performance and results, which are rewarding to the team. Contribution of members to the outcome of the activity Though every member executed distinctive tasks, the tasks culminated into the success of the team. Specifically my contributions were collection of firewood and lighting of the night fire. I further ensured that the fire kept burning through the night to scare away wild beasts. In addition, my expertise in map and compass reading enabled the team to find the location of the nearest town. Shortcoming in the leadership and

GDP Growth of Apple Company Essay Example | Topics and Well Written Essays - 500 words

GDP Growth of Apple Company - Essay Example nd services are primarily a luxury good for individuals within relatively developed nations, the focus that Apple should take is upon representing the main focus of their strategy and advertising to those that can afford such products and services. Naturally, this will encourage Apple to take a broad overview of GDP and purchasing power parity that exists within many different economies as a means of understanding what socio-demographic sectors and regions will most likely represent their consumer base. Taking the case of Europe as an example, one might be inclined to understand that the established and powerful Western European economies are the main areas in which Apple should focus its marketing. However, this is not quite the case. Due to the resurgence of Eastern Europe over the past decade, the overall purchasing power of these individuals cannot and should not be discounted. As figure 1 denotes, counties such as Latvia , Lithuania, Estonia, and Poland have noted some of the most drastic GDP growth figures over the past few years. As such, Apple would be highly remiss if it did not recognize these emerging markets and seek to represent a strategic focus on selling products and services to individuals within them. However, with that being said, it should also be noted that the economies of Western Europe cannot and should not be ignored either. As figure 2 denotes, after the 2007/2008 financial collapse that saw most of the world’s economies slow down significantly, Western European nations have posted impressive numbers for overall GDP growth. As such, a dual strategy should be employed by the firm as can be engaged through a relevant understanding of the statistics that have thus far been represented. One such approach would be to offer lower price products and services within the Eastern European markets while offering higher priced goods and service offerings to those individuals within Western Europe. What is being described and defined is not
