Most commonly‚ Citrobacter freundii lives as a normal occupant in the feces from the intestinal tract of humans and animals (1). C. freundii can also be found in soils‚ water‚ sewage‚ and food (1). Being a facultative anaerobe‚ C. freundii can live in both the absence and presence of oxygen (1). The bacterium’s optimal temperature is 37ᵒC (1). C. frundeii is also a chemoorganotrophic‚ which means that the microorganism requires an organic source of carbon to oxidize chemical bonds from for its

Unknown Lab Report #1 Unknown #1 April 25‚ 2012 Microbiology Spring 2012 MCB2010C Unknown #1 Introduction Identity of a microorganism has proven to be very significant. Doing so can help identify diseases and created treatment and cures for such diseases. As a result‚ various laboratory tests were performed to an unknown microbe (Unknown #1) found in the water of a nearby pond. By identify the microbe‚ the safety of the water will be known to those around it. Materials and Methods

Unknown Lab Report April 25th‚ 2006 Introduction The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures

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

Unknown Lab Report Unknown Organism #6 Ann Le (Phuoc) May 6‚ 2010 Dr. Carrington Microbiology Lab- MW 12:50 Le 1 I. Introduction My unknown organism #6 is Morganella morganii‚ which is a gram-negative bacillus rods commonly found in the environment and also in the intestinal tracts of humans‚ mammals‚ and reptiles as a normal flora. (3‚ 5) This bacterium Morganella morganii‚ was first discovered in the 1906 by a British bacteriologist named H. de R. Morgan. (2) Despite its wide

In the unknown identification labs‚ we have identified our unknown as Pseudomonas aeruginosa. Pseudomonas aeruginosa is Gram negative and rod shaped that we found to be motile in the lab. Our strain of P. aeruginosa formed colonies that were round in shape and had scalloped margins on nutrient agar. On our agar slant‚ the P. aeruginosa colonies had a filiform appearance on the edges. I think we correctly identified our unknown as P. aeruginosa because we performed several different tests‚ eleven

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
