Purification and expression of a novel bacteriocin, JUQZ-1, against <i>Pseudomonas syringae</i> pv. <i>Actinidiae</i> (PSA), secreted by <i>Brevibacillus laterosporus</i> Wq-1, isolated from the rhizosphere soil of healthy kiwifruit.

ABSTRACT: Kiwifruit canker, caused by Pseudomonas syringae pv. actinidiae (PSA), has led to significant losses in the kiwifruit industry each year. Due to the drug resistance feature of PSA, biological control is currently the most promising method. Developing biocontrol bacteria against PSA could help solve the issue of drug resistance generated during the chemical control of PSA to a certain extent. In this research, a Wq-1 strain that demonstrated excellent inhibitory activity against PSA was isolated from the rhizosphere soil of healthy kiwifruit. Based on the morphological characteristics and phylogenetic analysis of the 16S rRNA gene sequence, the isolated strain was identified as Brevibacillus laterosporus Wq-1. Bacteriostatic proteins were isolated from the cell-free cul
