Nutrient-Driven Metabolic Activation and Microbial Restructuring Induced by Endophytic <i>Bacillus</i> in Blight-Affected Forest Soils.

ABSTRACT: The climate-driven acceleration of forest disease outbreaks has intensified the demand for sustainable biocontrol strategies. In this study, we evaluated the effects of the endophytic bacterium Bacillus amyloliquefaciens csuftcsp75 on soil properties, microbial communities, and functional metabolism in soils affected by Pinus massoniana shoot blight. Soil physicochemical analysis, carbon substrate utilization profiling (AWCD), and diversity indices (the Shannon, Simpson, and McIntosh indices) were integrated to assess the microbial responses under different inoculation treatments. The csuftcsp75 treatment significantly improved soil nutrient availability-especially available phosphorus and potassium-and was associated with enhanced microbial metabolic activity and sustained f
