What benefits of Bacillus laterosporus have been cited in the scientific literature?
Bacillus laterosporus (also classified as Brevibacillus laterosporus) is cited in peer-reviewed research for plant growth promotion in maize, with studies reporting significant improvements in root weight, shoot weight, leaf weight, and chlorophyll content compared to untreated controls. The genome of strain K75 carries genes linked to indole-3-acetic acid (IAA) production and phosphate solubilization, two mechanisms the literature attributes to its observed growth-promoting activity.
On the biocontrol side, Bacillus laterosporus biopesticidal activity has been documented in the literature against insects across the Coleoptera, Lepidoptera, and Diptera orders, as well as against nematodes and mollusks. Strain B.O.D. harbors genes encoding chitinases, putative proteases, and mosquitocidal proteins, with demonstrated insecticidal activity against lepidopteran and dipteran pests. In brassica trials, endophytic colonization of leaf, stem, and root tissue is reported to cause a significant reduction in diamondback moth pupation.
