  • Thirty-nine gram-positive bacteria isolated from the rhizosphere of broccoli, pepper, rosemary, and tomato were tested in vitro for their antagonistic activity by the dual culture method against the phytopathogenic fungi Botrytis cinerea, Fusarium oxysporum f.sp. lycopersici, Pythium ultimum, and Rhizoctonia solani. Sixteen strains that were able to inhibit the radial growth of fungal colonies were spore-forming bacteria. Identification of these bacteria was done with BIOLOG system and PCR-RFLP analysis. A fragment of 749 bp located in the region of the RAPD marker SG-850 (EMBL accession n. AF0361405) specific for Bacillus cereus group, was amplified by PCR and digested with AluI restriction endonuclease. Eleven strains were identified as Bacillus cereus and one as Bacillus mycoides by both identification techniques, while the remaining four strains were identified as Bacillus badius (two strains), B. pumilis and B. subtilis by BIOLOG system, while they were not amplified by PCR. Most of the strains that showed antagonistic activity against the phytopathogenic fungi were able to produce chitinases and diffusible antibiotics and to form biofilm in in vitro tests. No siderophore and volatile antibiotic production was detected. A greenhouse trial was made to determine the biocontrol activity of B. cereus strain M123 (highly effective in vitro) and other putative antagonists belonging to Enterobacter aerogenes, Pseudomonas aureofaciens and Pseudomonas fluorescens species. Antagonists were used as a single strain or as a mixture against Fusarium oxysporum f.sp. lycopersici and Rhizoctonia solani. The B. cereus strain was effective in reducing the incidence of infection by both pathogens. (literal)
