Bacillus pumilus

Bacillus pumilus is a Gram-positive, aerobic, spore-forming bacillus commonly found in soil.[1]

B. pumilus spores—with the exception of mutant strain ATCC 7061—generally show high resistance to environmental stresses, including UV light exposure, desiccation, and the presence of oxidizers such as hydrogen peroxide.[2] Strains of B. pumilus found at the NASA Jet Propulsion Laboratory were found to be particularly resistant to hydrogen peroxide.[3]

A strain of B. pumilus isolated from black tiger shrimp (Penaeus monodon) was found to have high salt tolerance and to inhibit the growth of marine pathogens, including Vibrio alginolyticus, when cultured together.[4]

Use in agriculture[edit]

Bacillus pumilus strain GB34 is used as an active ingredient in agricultural fungicides. Growth of the bacterium on plant roots prevents Rhizoctonia and Fusarium spores from germinating.[5]
