“…Previously, we reported a similar observation in which an EU07 treatment of plants resulted in increased plant height in comparison to that observed with QST713 (Baysal et al, 2008). External applications of commercial acetoin and 2,3-butanediol, produced by Bacillus species, resulted in a dose-dependent stimulation of plant growth under optimum concentrations (Zuber et al, 1993).…”

Crop losses caused by insects, pests, and pathogens remain one of the major problems in sustainable agriculture. Environmental and health concerns regarding the overuse of pesticides, and the impacts of climate change on epidemics are immediate pressing issues. In addition, the breakdown of plant resistance by pathogen populations brings limitations to the genetic control of diseases. Biologics can be effective in all types of agricultural systems including organic, sustainable, and conventional. Beneficial microorganisms including Bacillus and Trichoderma species have been employed as environmentally safe biopesticides. Molecular and proteomic studies on biopesticides have revealed the nature of antibiotics, secreted enzymes, and inhibitory compounds. This review focuses on the current knowledge regarding biological agents and their metabolites including quorum-sensing molecules and volatile compounds, and how they can be used in pest and disease management programs.

An antifungal lipopeptide iturin A with strong activity against Fusarium oxysporum was produced by honey isolated strain Bacillus amyloliquefaciens BH072. For large-scale biocontrol application, the antifungal effect was deeply demonstrated by structure and mode of action. Cyclic structure and second structure were determined based on situ acid hydrolysis and Fourier Transformed-Infra Red (FT-IR) Spectra analysis. Structure of α-helix was predicted which might be associated with activity. Afterwards, antifungal mechanism of iturin A on F. oxysporum were investigated from fungal cell wall to the plasma membrane and finally to intracellular proteins by morphological, activity of alkaline phosphatase (AKP), conductivity, Malondialdehyde (MDA) and SDS-PAGE detection. Antifungal damage appears on not only the spore germination and mycelium growth of F. oxysporum, but also the leakage of cellular proteins. Moreover, growth of F. oxysporum could be inhibited in the presence of iturin A at a MIC of 2.5 mg/mL. Considered with its high production in previous work, B. amyloliquefaciens strain BH072 and iturin A might be a promising candidate for biocontrol.

To investigate the biocontrol mechanism of two antagonistic Bacillus strains (Bacillus subtilis MB14 and Bacillus amyloliquefaciens MB101), three in vitro antagonism assays were screened and the results were concluded that both strains inhibited Rhizoctonia solani growth in a similar manner by dual culture assay, but the maximum percent of inhibition only resulted with MB101 by volatile and diffusible metabolite assays. Moreover, cell free supernatant (CFS) of MB101 also showed significant (p > 0.05) growth inhibition as compared to MB14, when 10 and 20% CFS mix with the growth medium of R. solani. After in vitro-validation, both strains were evaluated under greenhouse and the results concluded that strain MB101 had significant biocontrol potential as compared to MB14. Strain MB101 was enhanced the plant height, biomass and chlorophyll content of tomato plant through a higher degree of root colonization. In field trials, strain MB101 showed higher lessening in root rot symptoms with significant fruit yield as compare to strain MB14 and infected control. Next to the field study, the presence of four antibiotic genes (srfAA, fenD, ituC, and bmyB) also concluded the antifungal nature of both Bacillus strains. Phylogenetic analysis of protein sequences revealed a close relatedness of three genes (srfAA, fenD, and ituC) with earlier reported sequences of B. subtilis and B. amyloliquefaciens. However, bmyB showed heterogeneity in among both strains (MB14 and MB101) and it may be concluded that higher degree of antagonism, root colonization and different antibiotic producing genes may play an important role in biocontrol mechanism of strain MB101.
