Studies were carried out to isolate microorganisms from corn and silage screened for their ability to inhibit F. moniliforme growth (strain 113F) in association with fumonisin detoxification. Among 150 isolates four Gram-positive bacilli and one yeast with inhibitory activity were selected. The inhibition zone ranged from 50 to 72.5 mm using cultures, and from 25 to 52.5mm for crude alcoholic extract. The isolates S9, S10, S69 (sporulated bacilli) and SE3071 (yeast) degraded 43, 48, 83 and 57% of the initial FB1 concentration, respectively. The pH increased gradually in the medium during incubation for biodegradation process.
