Unlike other bacilli which are predominately aerobic, B. licheniformis is a facultative anaerobe, which explains it's ability to grow in additional ecological niches and environments. Practice all cards Practice all cards Practice all cards done loading. Filamentous form, weakly undulate margin. The pathogenesis of Bacillus licheniformis, based on experimental studies, suggests there is localization in the placentomes after bacteremia. ducks) are common carriers of this bacterium; it is mostly found Its optimal temperature for enzyme secretion is 37C.
