ABSTRACT Rising energy prices and environmental problems led to the increase in alcohol demands in many aspects‚ like in making fuels. Many people are doing researches about making their own product so as to lessen their everyday expenses. Right now‚ Filipino scientists are in think of the search for alternative fuels‚ with the experts from the University of the Philippines in both Diliman and Los Banos campuses searching all over the archipelago for energy sources from the forests to the bottom

Syl Rogers Bio 210 Comparing Fermentation Rate of the S. cerevisiae Yeast in the presence of MgSO4‚ NaF and Sodium Pyruvate Hypothesis In the fermentation of rate of yeast‚ S. Cerevisiae‚ there will be a higher/ faster rate of ethanol production‚ However‚ using catalytic enzymes would make the rate more faster‚ and MgSo4 will have a higher rate of CO2 than that of NaF and Sodium pyruvate as it act as a more better catalytic enzyme than the others.

In the current practical that was undertaken the growth rate of yeast (S. cerevisiae) with differing carbohydrates sources : Glucose (C6H12O6)‚ Fructose (C6H12O6)‚ Lactose (C12H22O11)‚ Xylitol “(CHOH)3(CH2OH)2” and Water (H2O) as a Control were observed. “ Yeast are single-celled fungi which consist of more than one thousand different species which have been identified. The most commonly used yeast is Saccharomyces Cerevisiae which has been utilized for the production of bread‚ wine and beer for thousands

Sporosarcina ureae is usually isolated from urea‚ it could be concluded that Sporosarcina ureae is an alkalophile. There was only one group’s results for Saccharomyces cerevisiae. According to group SC-1’s results‚ it would seem that Saccharomyces cerevisiae is a neutrophile growing best at a pH level of 7.0. However‚ since Saccharomyces cerevisiae is a yeast‚ it would seem that it should be an acidophile. Results may have varied due to variance in procedure‚ contamination‚ and time allowed for growth

PROCEDURE: Part A (Effect of temperature on growth) 1) 15 tubes of glucose broth are provided and one set of 3 tubes are inoculated with each of the following cultures; Escherichia coli‚ Pseudomonas fluorescens‚ Micrococcus luteus and Saccharomyces cerevisiae. The last served as control. 2) One of the three tube of each culture is incubated at each of the following temperature: * 4°C * 37°C * 55°C 3) All the tubes are incubated within 5 minutes after inoculating.

Intro As a living organism yeast needs sugars‚ water and warmth to stay alive. which ferments the sugar in cereal (saccharo-mucus cerevisiae) to produce alcohol and carbon dioxide’ Baker’s yeast is produced from the genus and species of yeast called Saccharomyces cerevisiae. The scientific name of the genus of baker’s yeast‚ Saccharomyces‚ refers to "saccharo" meaning sugar and "myces" meaning fungus The typical yeast cell is approximately equal in size to a human red blood cell
