Abstract
The study aimed to detect both fungal contamination and fumonisin B1 (FB1) concentration in local Barley. The ability of five isolates from Fusarium moniliforme to produce FB1 were tested. The effect of some materials to detoxify FB1 were also studied. Genera of filamentous fungi were isolated from barley grains were Aspergillus, Penicillium, Alternaria, Mucor, Fusarium, Rhizopus Cladosprium, Helmenthosporium, Stemphylium and Ulocladium. Most of the barley samples collected through out the investigation were free from FB1 and four samples had traces concentration; two samples from Karkuk region contained 0.01 mg/g and two samples from Mousel region contained 0.01, 0.02 mg/g. Five isolates of F. moniliforme were ranged tested for production of FB1 on barley and the concentrations were between 6.4-10.2 Mg/g. Using Calcium hydroxide, Charcol and Fructose at two concentrations (1 and 2%) were resulted in detoxifying FB1 by 80.7, 84.7%, 54.7, 58.2% and 21.5, 24.9% respectively.
