Bacillus Cereus Bacillus cereus is a rod-shaped gram- positive bacillus that can be found in food‚ dust‚ dirt and sometimes soil. It is an aerobe and a facultative anaerobe that can form spores‚ which if activated at any point can begin to germinate and produce toxins. These spores that form from B. cereus are be resistant to heat and chemicals. B. cereus is found in approximately 25% of food sampled (3). Foods that are commonly associated with B. cereus are potatoes‚ rice‚ meat‚ vegetables

why eighteen different tests are performed so that you can compare your results with the table of possible unknowns. My unknown bacterium after performing the tests and comparing the charts is identified as Bacillus cereus. Bacillus cereus is a bacterium that grows best around 30-37°C. B. cereus cannot grow in high acidic‚ below pH of 4.5‚ or high alkaline environments of a pH above 9.3. You are likely to find this organism in the soil. This bacterium is able to form spores and therefore can withstand
