Abstract

Fruit and vegetables are susceptible to pathogen contamination during postharvest storage and transportation, leading to rot and mould growth.This study systematically reviews the development and application of Bacillus (and their antimicrobial metabolites) for reduced postharvest losses and enhanced preservation of fruits and vegetables.Based on an analysis of domestic and international literature, this study systematically elucidates the key antibacterial mechanisms of Bacillus spp., including colonizing the surfaces of fruits and vegetables, producing antimicrobial metabolites, secreting enzymes, and inducing resistance in fruits.It also thoroughly analyzes the effects of external factors such as temperature, humidity, water activity, and pH value on its antibacterial activity.Additionally, the practical applications and effectiveness of Bacillus in postharvest preservation are summarized.The biocontrol effect of Bacillus relies on multi-mechanism synergism, with suitable environmental conditions being essential for its stable performance.Accordingly, this review proposes future research directions in the targeted breeding of Bacillus spp.and the establishment of industrial standards, to guide further research and the application of green preservation techniques.
