Overview

Laboratory and greenhouse evaluation demonstrates broad fungal pathogen inhibition and enhanced growth in wheat and pepper, indicating strong agricultural biocontrol potential.

Key Points

To evaluate the antifungal biocontrol potential and plant-growth-promoting efficacy of bacterial strain Bacillus velezensis BV01 against major crop phytopathogens.
Assessed broad-spectrum pathogen inhibition across eight fungal species using dual-culture and sterile filtrate assays.
Identified the isolate via morphological, physiological, 16S rRNA, and gyrA phylogenetic analyses, and characterized its production of enzymes, indole-3-acetic acid (IAA), and siderophores.
Tested disease suppression of wheat root rot and pepper Fusarium wilt, as well as growth metrics, in greenhouse potted plant experiments.
Inhibitory rates against eight phytopathogens reached 57% to 83% in dual-culture assays and 36% to 92% in sterile filtrate assays.
Identified the production of cell-wall-degrading enzymes (protease, cellulase, β-1,3-glucanase) and growth-promoting compounds (IAA and siderophores).
Significantly suppressed wheat root rot and pepper Fusarium wilt while increasing plant height, stem diameter, and aboveground fresh and dry weights.
