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

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

Microbial Diversity and Ubiquity Microorganisms are microscopic organisms that are so small that that they can only be visualized by the aid of a compound-brightfield microscope. While we generally cannot see individual microorganisms with the naked eye‚ they are present in virtually every habitat known to man. Microorganisms can be prokaryotic—the bacteria or eukaryotic—the algae‚ protozoa or fungi. While viruses are acellular they are also studied in the scope of microbiology because

Biology 1003 - Cells: Size‚ Structure and Microscopy Introduction What is life? What are the key factors that biologists have defined that apply to every single organism on the planet? In the 17th century‚ due to the amazing advancement of the microscope‚ biologists created a theory to differentiate the living from the non-living called the cell theory. One concept from the theory is that all living organisms are composed of one or more cells. The importance of studying cells is akin to the
