ANTIBACTERIAL ACTIVITIES OF MYCOTOXINS FROM NEWLY ISOLATED FILAMENTOUS FUNGI
Praveena YSN1 and Padmini Palem PC2*
Five different mycotoxins viz., Aflatoxin, Malformin, Penitrem, Patulin and Deoxynivalenone (DON) were extracted from indigenous strains of Aspergillus niger, Aspergillus flavus, Pencillium expansum and Fusarium graminearum. Crude mycotoxins were further purified by column chromatography and characterized through TLC with reference to standards. Further antibacterial activities of crude as well as purified mycotoxins were evaluated against selected bacteria. Purified forms were highly inhibitory when compared to crude ones, which were evident through the increased zones of inhibition. The outcome of the present study demonstrates susceptibility of all the bacteria tested with isolated mycotoxins and out of all DON scored maximum inhibitory efficiency.
