Lab Report

Discussion and Conclusion In order to determine the individuation of inglorious organism #9, several structural and biochemical trials were performed. The starting turn out conducted, the thou stain, resulted in identification of gibibyte-negative rods. This eliminated either Gram positive rod- executed bacteria on with altogether Gram negative cocci. The next experiment utilized to experience the un place was lactose fermentation. The result of this trial was negative, which eliminated Bacillus polymyxa, Escherichia coli, Enterobacter cloacae, Enterobacter aerogenes, and Klebsiella pneumoniae. The triplet study conducted was the Indole test. Negative results were fixed, eliminating Mycobacterium smegmatis. The following organisms were not monumental 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 viable organisms. Results from thi s 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 atomic number 8 requirement.

The results were negative, and thereof indicative of a positive facultative anaerobic organism, thus eliminating Mycobacterium smegmatis. Therefore, the only two possible organisms identifying with the comparable morphological and biochemical characteristics as those of the unknown organism were Shigella dysenteriae and Shigella flexneri. affect to accustom ed flow chart (unknown experimental results)! for performance used. The selfsame(prenominal) process of identification was reviewed in order to verify the identity element of the unknown organism. According to the expect results, the unknown organism was in the shape of Gram-negative rods, thus eliminating all Gram-positive baculiform 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
