Unknown Lab Report Microbiology Unknown A Sonia Kabra November 26‚ 2014 Introduction There are numerous reasons for identifying unknown bacteria. Some of these organisms have distinct qualities that set them apart from one another‚ such as the exposure to certain environments. Through out the semester in the laboratory‚ we are able to encounter some of the few microorganisms that we as humans have come into contact with. With the knowledge gained from the sessions in the laboratory‚ we can now

their DNA to enable them to come back to life in the right conditions. They are able to survive in most extreme living conditions including with and without oxygen‚ there are various types of bacteria such as Cocci/Coccus (a round bacteria called staphylococcus aureus‚ found on the skin‚ in the nose or mouth‚ cannot be treated by antibiotics)‚ bacilli/bacillus (a rod shaped bacteria called E coli usually spread by touch or badly prepared/ raw foods‚ can be treated with antibiotics)‚ and (a spiral shaped

Purpose: To identify an unknown bacterial specimen using basic laboratory technique and biochemical tests. The unknown bacteria will be one of the following: Enterococcus faecalis‚ Staphylococcus saprophyticus‚ Escherichia coli‚ Enterobacter aerogenes‚ Proteus vulgaris‚ Salmonella [I assume typhimurium]‚ or Shigella [either flexneri or sonnei‚ we used both in our lab during the semester]. Procedure {and observations}: Observe bacterial colony morphology. {Colonies are large‚ beige or

Paraphrase: Bacillus subtilis‚ known also as the hay bacillus or grass bacillus‚ engage for survival and competitive success in its natural habitats‚ B.subtilis shed light on the conduct of this organism throughout industrial fermentation. Certainly‚ the high adaptability of B.subtilis to environmental changes and insults stands at the basis of its success‚ not only in its character but also in marketable applications. Paraphrase: S.typhi might be younger than the split between the humans and the

The Danger of Antimicrobial Usage: Triclosan Essay Weren’t anti-microbial agents considered safe for humans to use and not suppose to be harmful in nature? In recent studies‚ triclosan‚ an antibacterial compound is shown to be a harmful agent to humans rather than being helpful in keeping bacterial illnesses away. Presently‚ antimicrobials agents triclosan and triclocarban are examples of widely used antimicrobials agents in personal care products in United States and many other countries

Aspergillus flavus‚ yeast species such as Candida lipolytica‚ Mucor plumbeus and Staphylococcus aureus. Its combination along with clove oil has been impressive and effective against A. flavus. The cinnamon oil has antimicrobial action in the range 10-150 μg ml − 1. Another intriguing fact about cinnamon is its role in altering or changing the expression of a gene icaA which plays a role in the formation of biofilms. Staphylococcus epidermidis is one of the causes of biofilms which is why it has emerged
