While microbes are often viewed negatively due to their association with many human illnesses‚ microbes are also responsible for many beneficial processes such as industrial fermentation (e.g. the production of alcohol and dairy products)‚ antibiotic production and as vehicles for cloning in higher organisms such as plants. Scientists have also exploited their knowledge of microbes to produce biotechnologically important enzymes such as Taq polymerase‚ reporter genes for use in other genetic systems

the microorganism was identified as Enterbacteriaceae Enterobacter aerogenes. INTRODUCTION Microbiology is a specialized area of biology that places an emphasis on microorganisms. Several microorganisms are included in this subject‚ such as bacteria‚ fungi‚ algae and protozoa. The most important fact that should come out of microbiology is the “profound influence” that microorganisms have on the aspects of earth (Cowan‚ 2012). The objective of this project was

We will also study some larger organisms which are included in the taxonomic kingdoms covered in this unit. God has created an amazing world around us that is teeming with life that we cannot see as we go about our days. Isaiah 45:18 states‚ “For thus saith the LORD that created the heavens; God himself that formed the earth and made it; he hath established it‚ he

Grams staining method and reliability of this method. According to me‚ Grams staining process is a simple technique that assists in recognition of etiological agent and therefore can be called as one of the most significant staining practices in microbiology. Though‚ Gram is concerned that the staining process developed by him is imperfect because not all bacteria can be stained by it‚ but in my opinion‚ when we pour ethanol over the slide to wash away the dye then only definite bacteria can retain

elevated tolerance towards arsenate and arsenite (MTC 400 mM and 20 mM respectively) while tolerance to other heavy metals like Cu2+‚ Cd2+‚ Cr2+ and Pb2+ (MTC < 3 mM) was moderate. Plasmid bearing isolates were tested for their resistance against five antibiotics‚ out of which all except one were found to be resistant against ampicillin. Plasmid curing was successfully carried out with EtBr for few isolates. Compared to wild cured strains showed
