|Categories:||Causes hemolysis; spore forming; motile|
|Etymology:||Genus name: small rod|
Species epithet: wax colored
|Type Strain:||ATCC 14579 = CCUG 7414 = NCTC 2599|
||Large, opaque, grey-yellow, granular, flat colonies (diameter 5-10 mm). Most strains produce a clear broad zone of hemolysis on blood agar.|
||Large (1 x 5-10 µm) motile rods, centrally located endospores can sometimes be seen as uncolored regions after Gram staining of cells from older cultures. May form spores.|
|Gram +/Gram -:||G+ (Cells from older cultures can appear as G - because the cell wall degenerates)|
|Other Enzymes:||Lecithinase +|
|Fermentation of carbohydrates:||
Other carbohydrates: Fructose +, D-mannose -, ribose +, xylitol -.
||MYP agar is often used for confirmation of suspected B. cereus colonies from food samples.|
|16S rRNA Seq.:|
||About 250 species have been described within the genus Bacillus. B. cereus is very closely related to Bacillus anthracis and Bacillus thuringiensis.|
