Bacillus pumilus spores—with the exception of mutant strain ATCC 7061—generally show high resistance to
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]
Genome and cell structure
Bacillus pumilus contains one circular chromosome including about 4000 genes and 3600-3900 proteins with varying length in the range of 3.7 to 3.8 Mbp. 41% of the DNA base pairs in B. pumilus are G-C. The cellular structure of B. pumilus is similar to other Bacillus species such as B. subtilis, B. megaterium, and B. cereus, the outer layer of the peptidoglycan cross-links in B. pumilus is covered by teichoic and lipoteichoic acids same as the most other Gram positive bacteria. These acids contain polyglycosyl phosphates with mono- and disaccharides as their monomers that can play a role in adhesion to different surfaces like the host cells.[5][6] On the other hand, these phosphate groups on the surface of B. pumilus can provide net negative charge on the cell surface that allowing to capture some essential cations such as Ca2+ and Mg2+ that are necessary for cell life.
Industrial use
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.[7]
Bacillus pumilus (ATCC 27142) may be utilized (as a
