Chapter 4 - Methane production 4.1 Microbial consortia and biological aspects of methane fermentation 4.2 Molecular biology of methanogens 4.3 Developments in bioreactor technology References Methane fermentation is a versatile biotechnology capable of converting almost all types of polymeric materials to methane and carbon dioxide under anaerobic conditions. This is achieved as a result of the consecutive biochemical breakdown of polymers to methane and carbon dioxide in an environment

The rate of fermentation is faster when there is more sucrose concentration because it means there is more glucose‚ which in return means more carbon dioxide production. The sucrose concentrations were 0%‚ 1%‚ 5%‚ and 10%. The 0% sucrose concentration is just normal‚ plain water. Yeast‚ a single celled eukaryotic fungi‚ was put into the solutions. It uses fermentation to make more carbon dioxide and alcohol. In the 0% solution‚ no carbon dioxide had been produced. At the start‚ the depth of the

Investigation on Effects of Different pH on Enzyme Activity How does the different pH buffers affect activity of potato enzyme/extract? Introduction: Proteins are polymers that are made up of smaller units/monomers called amino acids. There are 20 different types of amino acids‚ thus make up many different combinations in types‚ numbers of amino acids as well as their orders – an explanantion for why there are so many proteins. Every protein‚ due to various reactions of amino acids to each

Enzymes are catalysts that are used to speed up chemical reactions. Adding inorganic catalysts to reactants increase the rate of most chemical reactions. However‚ all enzymes are different and there are numerous amounts. Many enzymes are essential for life and reactions would not happen rapidly to maintain life with the help of enzymes. Specific enzymes lower the activation energy for specific reactions and shapes. Activation energy is required to start a chemical reaction. This occurs when energy

Enzyme Activity Lab Hypothesis: 1] Are enzymes reusable? Yes‚ enzymes are reusable. 2] Which of the following do you think contain catalase? [Manganese dioxide‚ chicken meat‚ apple‚ carrot‚ potato‚ or chicken liver] I think that the manganese dioxide‚ apple‚ and carrot contain the catalase. 3] Would grinding the materials affect enzyme activity? I think that grinding the materials will increase enzyme activity. 4] Would temperature affect enzyme activity? I think that
Premium Enzyme Catalysis Chemical reaction
Introduction Enzymes are proteins produced by living organisms to speed up the rate in which chemical reactions occur. This process can happen fast‚ slowly‚ or stop the chemical reaction all together depending on the temperature‚ pH and concentration. Catalase is one of the most common enzymes. It is found in living organisms and is used to break down hydrogen peroxide. This must happen because hydrogen peroxide is considered toxic to cells in the body. However‚ when catalase is used it breaks

Discuss the effects of increased concentration in transport markets. Concentration ratio refers to the market share of the largest firms in an industry. For example‚ a 5 firm concentration ratio of 65% means that the 5 largest firms have more 65% of market sales. If the concentration ratio increased‚ then 1 or 2 firms may start to dominate the market and the firms will be able to exercise Monopoly power. (in UK legal definition of a monopoly is a firm with more than 25%) This is likely to cause many

Design your own experiment: Effect of pH on enzymatic activity Background Information: Trypsin is a protease which conducts hydrolysis forming peptides. It is an enzyme which is secreted by the pancreas into the small intestine and works best in an alkaline environment. Egg white is used in this practical as it is found to contain the protein/ enzyme trypsin. pH is the measure of the amount of H+ ions in a solution‚ these ions affect the shape of the enzyme. Hypothesis: That as pH increases
