Control by Antibiotics and Antiseptics Lab Report Georgia State University Introduction The fact that each bacterial species‚ and even some of their respective strains‚ responds uniquely to a given antimicrobial makes it necessary to have methods‚ which provide researchers and clinicians with measurable susceptibilities. This need has become prevalent since the rising of later generations of antimicrobial compounds achieved by chemical modifications of the naturally occurring antibiotics. By

By examining where and when genes are expressed in a cell or organism‚ one can acquire valuable hints to its function‚ for genes compile the genetic make-up of an organism and exploring the function of genes is helping to uncover the complexity of ourselves and of other forms of life (1). Significant developments have been made in gene monitoring techniques specifically in DNA microarrays which only very recently revolutionized genome expression analysis (1). Despite continuous improvements and

Mark Duanmu‚ Rika Fujita‚ Alex Chung October 8‚ 2011 Biology (Honors) P7 Gill Temperature and Yeast Fermentation Introduction: Saccharomyces cerevisiae‚ commonly known as baker’s yeast‚ is an key ingredient used mainly when baking bread or making alcoholic beverages. The main role of the yeast is to convert the sucrose into carbon dioxide (CO2) and ethanol. For example‚ when baking bread‚ the yeast ferments the sucrose within the dough and so CO2 and ethanol is released‚ causing the bread

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
