Anti-Fusarium moniliforme activity and fumonisin biodegradation by corn and silage microflora

Studies were carried out to isolate microorganisms from corn and silage scr eened for their ability to inhibit F. moniliforme growth (strain 113F) in a ssociation with fumonisin detoxification. Among 150 isolates four Gramposit ive bacilli and one yeast with inhibitory activity were selected. The inhib ition zone ranged from 50 to 72.5 mm using cultures, and from 25 to 52.5 mm for crude alcoholic extract. The isolates S9, S10, S69 (sporulated bacilli ) and SE3071 (yeast) degraded 43, 48, 83 and 57% of the initial FBI concent ration, respectively. The pH increased gradually in the medium during incub ation for biodegradation process.
