Hypothetically draw the Dichotomous key for Micrococcus luteus, Bacillus subtilis, Bacillus, Megaterium, Bacillus cereus, E.coli, Serratia Marcescens, and Enterobacter aerogenes based on colony morphology. results of catalase test, (lactose, sucrose and glucose fermentation tests) and other biochemical tests for its accurate identification.

Identify a biochemical test that can differentiate Enterobacter agglomerans from Enterobacter cloacae

A physician obtains a specimen from a patient with tuberculosis. This sample has one viable bacteria, an organism with slow doubling time in vitro of 48 hours, which corresponds to the growth rate constant in vitro of 0.04 h^-1. Estimating that the biomass of a single mycobacterial organism is 2.3x10^-13 g and that this organism is immediately going to enter the log phase, how many hours will it take to produce 10^-6 grams of biomass?

Describe the growth of Staphylococcus aureus and Saccharomyces cerevisiae at low pH (3-3.5).
