Genomic and biological control of Sclerotinia sclerotiorum using an extracellular extract from Bacillus velezensis 20507.

ABSTRACT:

Introduction

Sclerotinia sclerotiorum is a known pathogen that harms crops and vegetables. Unfortunately, there is a lack of effective biological control measures for this pathogen. Bacillus velezensis 20507 has a strong antagonistic effect on S. Sclerotiorum; however, the biological basis of its antifungal effect is not fully understood.

Methods

In this study, the broad-spectrum antagonistic microorganisms of B. velezensis 20507 were investigated, and the active antifungal ingredients in this strain were isolated, purified, identified and thermal stability experiments were carried out to explore its antifungal mechanism.

Results

The B. velezensis 20507 genome comprised one circular chromosome with a length of 4,043,341 bp, including
