Abstract

Introduction: Most species of Bacilli like BACILLUS CEREUS have the potential to produce antifungal compounds, which are placed in ITURIN group, and for this reason these bacteria are one of the most important bacteria which could be used in the BIOLOGICAL CONTROL of pathogenic plant fungi.Aim: Evaluation of antifungal activity of BACILLUS CEREUS against some pathogenic plant fungi and screening of their antifungal metabolites were the major aim of this research. Material and Methods: In this investigation, a few local and modified isolates of BACILLUS CEREUS bacterium were cultured in nutrient broth medium on 30°C and 100 rpm for 24 hours. Their antifungal activity against VERTICILLIUM DAHLIAE ATCC 29091 and PHYTOPHTHORA INFESTANS ATCC 16981 fungi were evaluated via Agar wells method. Growth and the production of these antifungal metabolites of the screened bacterium in same medium for the factors like carbon source(Glucose, Arabinose, Lactose and Saccharose) nitrogen source(Yeast extract, Peptone, Ammonium nitrate and sodium nitrate), pH (~4-6, 7, 8-10) and temperature (26-29°C, 29-32°C, 35-32°C) were optimized. The metabolites were extracted and evaluated in comparison of ITURIN A and Surfactin through the High Performance Liquid Chromatography (HPLC).Results: The results indicated that the fungi growth was inhibited. Antifungal peptides of ITURIN group, such as ITURIN A and Surfactin, were produced in nutrient broth medium with glucose and peptone at neutral pH and 32-35°C. Chromatograms of HPLC were revealed the active compounds by identical peaks with the similar retention time as antibiotic compounds belonging to the ITURIN group. Antifungal activity and synergistic effects of ITURIN A, Surfactin and antifungal metabolites of BACILLUS CEREUS were evaluated via Agar wells method. The average index of growth suppression of V.dahliae via Agar wells method in presence of 50ml of a suspension of BACILLUS CEREUS, it´s metabolites, ITURIN A (1mg/ml), Surfactin (1mg/ml) and the complex of ITURIN A and Surfactin were 20, 16, 10, 10, 14 mm, consequently and mixture of the last three treatments led to 24 mm. Conclusion: The results indicate that This bacterium and its components can be suitable candidate for BIOLOGICAL CONTROL of some plant pathogenic fungi.
