Microbiological and Mycotoxigenic Studies on Nigella sativa seeds exposed to gamma nidiation

Abstract

This• work was carried out to investigate the microbial contamination and mycotoxins occurrence on the N.. seeds collected from deferent governorates in Egypt. The effect of gamma radiation for elimination this contamination isolation and identification of the radioresistant microbes and the pathogenic organisms were dete1mined. The effect of the antimicrobial activity of the extracted oils on the isolated strains and aflatoxin •production was also studied. Effect of gamma radiation and extracted oils on the ultrastructure using electron microscope on certain selected organisms was also investigated in this work.
