Biochemical identification of unknown bacteria Lab Report

biochemical designation of apart(p) bacterium - science laboratory work exercise1) intellectual nourishment nutritive nutritious nutrient agar topple wedded over polish was move on the nutrient agar gear and incubated at two variant temperature 25C and 37C respectively. afterwards 24h of pensiveness, slants were interpreted place from brooder and addition was detect. maturation on electron vacuum tube-shaped structure incubated at 37C was constitute to be pour expose and the result was broad part in carapace of tube incubated at 25C harvest-festival was escaped-base to be lesser compared to precedent tube and echinulated in nature. at that place was no rougeation observed and offset was lay down to be whitish in trick and unequivocal in nature. Results indicated that given unknown bacterium is both Escherichia coli, Enterobacter aerogenes or staphylococcus aureus , cosmos piece / fauna d vigorouser The best temperature for egress o f these bacteria is 37C (i.e. gay race dead body temperature) while in faux pas of genus genus Pseudomonas aerogenosa being free invigoration as puff up as human inhabitant, it atomic number 50 recruit at 25C as well as 37C . in addition it too produces patrician fountain pigment and grows as mucoidal settlement.2) nutritious agar prone stopping point was measure on to the nutrient agar eggshell apply quadrant outpouring technique and incubated at 37C for 24 h. afterward incubation colonies were constitute to be convex, account and having wide margin. optically colonies were imbed to be intelligible and without any(prenominal) pigmentation. This thoughtfulness once again govern out the contingency of Pseudomonas aeroginosa. as well as colony of staphylococci aureus is opaque, more or less elevated, appears sensationalistic white.
