Bacillus amyloliquefaciens L-H15 is a plant growth promoting rhizobacteria (PGPR) isolated from the cucumber seedling substrate collected in Beijing, China. The complete genome of B. amyloliquefaciens L-H15 consists of one single circular chromosome (3,864,316 bp) without any plasmid. From the genome, we identified clusters responsible for non-ribosomal synthesis of secondary metabolites, and genes related to the plant growth promotion hormone such as indole-3-acetic acid (IAA) and acetoin secretion. In addition, genes that contribute to biofilm formation were also found on the genome of L-H15. Complete genome information enables further study on the beneficial interactions between B. amyloliquefaciens L-H15 and host plants, and the future application of B. amyloliquefaciens L-H15 as biofertilizer and biocide.

P852, a novel cyclic peptide isolated from Bacillus amyloliquefaciens L-H15, showed potent antifungal activity against several major plant fungal pathogens including Fusarium oxysporum. To elucidate the antifungal mechanism, the impact of P852 on the cell morphology and membrane permeabilization of F. oxysporum was studied.

Bacillus amyloliquefaciens L-H15 with broad spectrum antifungal activity was used as a biocontrol agent to suppress Fusarium oxysporum and other soil-borne fungal plant pathogens. Two antifungal fractions were isolated by bioactivity-guided reversed-phase high-performance liquid chromatography. The two compounds were identified by tandem Q-TOF mass spectroscopy as C15 Iturin A (1) and a novel cyclic peptide with a molecular weight of 852.
