WebA few B. cereus strains are non-motile. They are aerobic or facultatively anaerobic. B. cereus cultures usually are strongly hemolytic and produce 2-4 mm zone of complete (β) hemolysis surrounding growth. This characteristic helps in differentiating B. cereus from B. anthracis which is non-hemolytic. They are usually catalase-positive. WebBacillus species are easily recovered on blood and chocolate agars and grow optimally at environmental temperatures (25 to 37°C). All species except B. anthracis are motile and beta-hemolytic on blood agar. Colonies have an irregular perimeter and appear dull gray and opaque on sheep blood agar.
