The effect of environmental factors such as temperature‚ osmotic pressure‚ oxygen concentration and pH on microbial growth and survival Abstract: Microbial growth can be affected by different environmental factors such as temperature‚ osmotic pressure‚ oxygen concentration and pH. Six experiments were carried out in this report testing for microbial growth against different environmental factors. Good aseptic techniques were used to prevent contamination‚ resulting in a uniform set of results

Bacterial Fermentation Secondary article Article Contents Volker Mu¨ller‚ Ludwig-Maximilians-Universita¨t Mu¨nchen‚ Munich‚ Germany . Introduction Under anaerobic conditions‚ in the dark and in the absence of electron acceptors‚ organic compounds are catabolized by strictly anaerobic or facultatively anaerobic bacteria by internally balanced oxidation–reduction reactions‚ a process called fermentation. In fermentation‚ the organic compound serves as both electron donor and acceptor‚ and adenosine

Wet Mount Slide = a microscope slide of a liquid specimen covered with a cover glass. Yeast = a single celled fungi. Budding = a true characteristic method of asexual reproduction among yeasts where budding of a new cell from a parent cell can be observed. Mold = multicellular masses of filamentous fungal growth.

Abstract Research will be done and two experiments will be conducted to evaluate ethanol as a fuel‚ the experiments are Fermentation and Calorimetry. Fermentation will find the best combination of sugar and yeast for optimum ethanol production and the Calorimetry experiments test ethanol against other alcohols and fuels to see how it matches up in terms of energy production. Fermentation shows glucose and baker’s yeast as the fastest producers of ethanol and the calorimetry proves that ethanol and

food source. Yeasts reproduce rapidly through fission or budding and grow especially well in substances containing sugar. Baker ’s yeast enzymes convert sugar to ethanol and carbon dioxide. Baker ’s yeast is cultivated from the strain Saccharomyces cerevisiae because of its superior fermentation abilities. The yeast propagates in pure culture using special culture media comprised of melasse and other ingredients. With respect to their metabolism baker ’ yeasts are facultative anaerobe. They can
