Read source ↗ All evidence

Summary

This paper, published in the Journal of Applied Microbiology, reviews the dual capacity of Bacillus subtilis to act simultaneously as a biocontrol agent against fungal and bacterial plant pathogens and as a plant growth-promoting rhizobacterium. It likely synthesises mechanistic evidence covering the production of lipopeptides, volatile organic compounds, and phytohormones, alongside colonisation behaviour in the rhizosphere. The review situates B. subtilis as a candidate for reducing reliance on synthetic agrochemicals within integrated crop management approaches.

UK applicability

Findings are broadly applicable to UK arable and horticultural systems, where there is growing regulatory and policy pressure to reduce synthetic fungicide and fertiliser inputs; B. subtilis-based biostimulants and bioprotectants are already registered for use in the UK and align with post-Brexit agri-environment scheme objectives.

Key measures

Biocontrol efficacy (pathogen suppression rates); plant growth parameters (root/shoot biomass, yield); antimicrobial metabolite production; plant growth promotion indices

Outcomes reported

The study likely examined the dual functional roles of B. subtilis as both a biocontrol agent against plant pathogens and a plant growth-promoting rhizobacterium (PGPR), reporting on mechanisms such as antimicrobial compound production, induced systemic resistance, and growth promotion metrics.
