Antifungal potential of <i>Bacillus</i> strains: implications for biocontrol strategies in food safety and sustainable agriculture.

ABSTRACT:

Introduction

Microbial spoilage and fungal phytopathogen infections significantly reduce the shelf life of perishable foods, creating major challenges for both agriculture and food supply chains. Bacillus species are known producers of antifungal metabolites such as lipopeptides and volatile organic compounds (VOCs), offering a sustainable alternative to synthetic fungicides.

Methods

This study evaluated the antagonistic activity of four Bacillus strains, H6 (Bacillus velezensis), S15 and S40 (Bacillus subtilis), and S32 (Bacillus cereus) against nine fungal phytopathogens, including those affecting tomatoes. Assessment methods included 108 dual-culture assays, in vitro lipopeptide bioassays, VOC-mediated inhibition tests, and PCR sc
