Broad antibiosis activity of <i>Bacillus velezensis</i> and <i>Bacillus subtilis</i> is accounted for by a conserved capacity for lipopeptide biosynthesis.

ABSTRACT: We evaluated 284 strains from 15 species across five genera in the Phylum Bacillota (Bacillus, Priestia, Cytobacillus, Neobacillus, and Gottfriedia) for antibiosis activity against the pathogenic oomycete, Phytophthora nicotianae. Fifty-eight strains were strong inhibitors, while 41 and 185 were weak and noninhibitors, respectively. Only Bacillus strains were strong inhibitors, and inhibitory metabolites were most frequently (55 of 58 strains) expressed from five species (B. pumilus, B. safensis, B. altitudinis, B. velezensis, and B. subtilis). Strongly inhibitory strains from B. velezensis (all) and B. subtilis (all but one) were also strong inhibitors of the fungal pathogens Fusarium oxysporum,
