Effects of Activators and Ethanol on Fermentation Rates In this lab we examined how the rate of fermentation is influenced by the type of substrate‚ and activators and inhibitors. We used four fermentation tubes in which we separately combined yeast with MgSO4‚ pyruvate‚ ethanol‚ and glucose. At five minute intervals we recorded the volume of gas produced in each fermentation tube. Our results are displayed in the graph. Our results supported the prediction that pyruvate is an activator

5.3.7 Effect of carbon supplements Supplementation of sugars‚ which may act either as carbon sources or inducers‚greatly affect the growth of microorganism. In case of CMCase‚out of the supplemented sugars‚glucose‚sucrose‚maltose‚lactose‚wheatbran and CMC‚ wheat bran show maximum increase in enzyme production. On addition of glucose‚ maltose‚ lactose‚wheat bran and xylan‚ the maltose resulted in an increment in xylanase production (24.96 IU/ml) by SmF. An induction in the enzyme production/activity

Effects of SO2 On Fermentation Rates Purpose SO2 is the primary inhibitor for natural microbiological growth in wine. It prevents the browning of juice by inhibiting phenol oxidase activity and kills the natural yeast cells for the utilization of fermentation-controlled commercial Saccharomyce strands (Boulton et al. 1996). SO2 is pH and temperature dependent and can exist as several forms. The bisulfate form (HSO3-) can complex with soluble solids such as anthocyanins and acetaldehydes to become

Studying the pH of Strong Acid‚ Weak Acid‚ Salt‚ and Buffer Solutions The purpose of the current experiment was to determine the pH of various hydrochloric acid and acetic acid solutions‚ to determine the pH of various salt solutions‚ to prepare a buffer solution‚ and determine the effects of adding a strong acid and strong base to the buffer solution versus adding a strong acid and strong base to water. The measured pHs for the hydrochloric acid solutions were 1.6‚ 2.2‚ 2.9‚ and 3.8. The measured

Does the PH level of acids in our stomach affect the digestion proteins? Yes‚ if the acidity in my/a stomach is high in terms of the PH balance then the proteins in our stomach will be digested faster because acids are known to breakdown and eat away at many objects. The purpose of this project was to observe how the digestion of protein varies at different pH levels. This project in my eyes helps society by finding the best types of food (i.e. ones with higher/ lower acidity and pH balance)

Executive Summary The recent acquisition of French energy company Alstom by General Electric has made a lot of headlines in the world recently. This is one of the largest acquisitions by the General Electric and involved a lot of complexities. The Alstom’s board of directors was ready to cut the deal with General Electric but French government has made this deal as the national pride and tried to interfere. They opposed this deal on the ground of loss of jobs in France but in reality the French

Effects of Temperature on Enzyme Biology Introduction In order to understand the activity of enzymes at different temperatures the ability of the enzyme to function can be measured. This is important in many applications such as Polymerase Chain Reaction for forensics as well as genetics research where manipulation of temperature-dependent enzymes allows for replication of DNA segments. Bennett states‚ “when the energy - measured
