Inhibition of aflatoxin contamination in rice by Cladosporium fulvum.

Cultural and morphological studies indicated that a fungal isolate with characteristics typical of Cladosporium fulvum [Fulvia fulva] has inhibitory potential against Aspergillus parasiticus in rice dextrose agar and in rice grains. Antagonistic activity of F. fulva against A. parasiticus was temporary for the first few days of incubation. Inhibition of growth of A. parasiticus was observed with 5-d-old cultures of F. fulva and complete suppression of growth was seen with 7-d-old cultures. Pigment produced by F. fulva is believed to possess an inhibitory compound and its effect on A. parasiticus includes modifying the morphology and altering the germination capability of the organism. The pigment produced by F. fulva was fungistatic to A. parasiticus but non-toxic to chick embryos and mice.
