BIOCONTROL OF ALTERNARIA TENUIS DAMPING-OFF OF TOMATO AND PEPPER WITH BACILLUS SPP. STRAINS

Bacillus spp. strains have been identified as producers of different kinds of inhibitory compounds for filamentous fungi. The previous experiments done in the Genetic Engineering Laboratory of the Faculty of Biotechnology, Bucharest, have shown that the Bacillus subtilis strains B2, mB2.9, tB2.2 and B. licheniformis B40, mB40.5, tB40.2 have antifungal potential and plant growth promotion activity. Our study refers to different mechanisms involved in those activities of Bacillus spp. strains (lipopeptide, indole acetic acid and HCN production).
