Lab Report

Discussion and Conclusion In order to determine the identicalness of inglorious organism #9, several structural and biochemical trials were performed. The start turn out conducted, the thou stain, resulted in identification of gibibyte-negative rods. This eliminated on the whole Gram positive rod- executed bacteria on with every Gram negative cocci. The next experiment utilized to keep in line the un determine was lactose fermentation. The result of this trial was negative, which eliminated Bacillus polymyxa, Escherichia coli, Enterobacter cloacae, Enterobacter aerogenes, and Klebsiella pneumoniae. The threesome study conducted was the Indole test. Negative results were goaded, eliminating Mycobacterium smegmatis. The following organisms were not evidential for the Indole test: Proteus vulgaris, Shigella flexneri, genus Pseudomonas aeruginosa, and Salmonella typhimurium. Motility was next determined in order to further narrow down the realistic organisms. Resul ts from this test indicated that the hidden organism was non-motile. This eliminated Serratia marcescens, Alcaligenes faecalis, Proteus vulgaris, Pseudomonas aeruginosa, and Salmonella typhimurium. With merely a few possible organisms left that identified with the unknown, the O/F test was applied to determine group O requirement.

The results were negative, and thereof indicative of a positive facultative anaerobiotic organism, thus eliminating Mycobacterium smegmatis. Therefore, the only two possible organisms identifying with the similar morphological and biochemical characteristics as those of the unknown organism were Shigella dysenteriae and Shigella flexneri. concern to acc ustomed flow chart (unknown experimental res! ults) for performance used. The comparable process of identification was reviewed in order to verify the identity of the unknown organism. According to the evaluate results, the unknown organism was in the shape of Gram-negative rods, thus eliminating all Gram-positive bacillar along with all Gram negative cocci bacteria. The expected results...If you call for to get a full essay, order it on our website: OrderEssay.net
