What benefits of Bacillus mojavensis have been cited in the scientific literature?
Bacillus mojavensis — also classified in the literature as Bacillus axarquiensis and Bacillus malacitensis — has 12 benefits reported across peer-reviewed research, covering plant growth promotion, abiotic stress tolerance, and biocontrol activity. These are experimental findings from published studies, not approved label claims or regulatory endorsements.
On plant growth, strain PRN2 is reported to significantly enhance growth parameters in peas (Pisum sativum) and chickpeas (Cicer arietinum). Strain I4 improved shoot length, root length, and biomass in durum wheat under salt stress while preserving membrane integrity, leaf chlorophyll, and antioxidant enzyme activity. Strain BZ-13 is cited for improving growth and photosynthetic attributes — including PSII quantum yield and total chlorophyll — in ashwagandha (Withania somnifera) under silver nanoparticle stress.
Multiple Bacillus mojavensis strains are reported to produce IAA and siderophores, solubilize phosphates, and show nitrogen fixation activity (nifH and nifD nitrogenase genes detected), all under heavy-metal conditions. For biocontrol, strain ZA1's bioactive metabolites achieved 60.95% in vitro inhibition of Colletotrichum coccodes. Strain dxk33 reduced Fusarium solani root rot disease index by 72.19% in Cunninghamia lanceolata and enhanced rhizosphere C-, N-, and P-cycling enzyme activity in the same host.
