<i>Bacillus atrophaeus</i> DX-9 biocontrol against potato common scab involves significant changes in the soil microbiome and metabolome.

ABSTRACT: Potato common scab (CS) is a worldwide disease, caused by Streptomyces spp., and its presence reduces the market value of potatoes. A nontoxic and potentially effective approach in many control strategies is the use of antagonistic microbes as biocontrol agents. In this study, Bacillus atrophaeus DX-9 was isolated and assessed for its ability to protect against CS. Through integrated metagenomic and metabolomic analyses, changes in the soil microbial community structure and soil properties were analyzed to understand the effects of Bacillus atrophaeus DX-9 on CS. These studies revealed that DX-9 inoculation could significantly decrease CS disease rate, disease index, and the number of CS pathogens, along with an increase in soil N and P content.
