Description:This photograph depicts the colonial morphology displayed by Gram-positive Bacillus megaterium bacteria, which was grown on a medium of sheep’s blood agar (SBA), for a 24 hour time period, at a temperature of 37°C. The overall colonial morphology displayed by B. megaterium is very similar to that displayed by B. anthracis. See PHIL 12382, and 12384, for other views of this culture plate, and these bacterial colonies.
B. megaterium is one of the largest known soil-inhabiting bacteria, hence its Latin name. It is also not normally thought of as a pathogenic organism. Due to its ability to produce penicillin amidase, this bacterium is used in the pharmaceutical industry when manufacturing penicillin, as well as in the modification of various corticosteroids. As an endospore-forming organism, B. megaterium can survive in very harsh environments, only becoming reanimated when conditions become favorable.
