In the present study to identify potential bio-control agents against A. flavus and aflatoxin contamination we have screened eighty bacteria, 40 actinomycetes and 40 fungi which were isolated from rice straw compost prepared at ICRISAT.. All bacteria and actinomycetes were studied for their antagonism against A. flavus by double layer method on GCY medium. Among them eight bacteria (CDB 15, CDB 16, CDB 30, CDB 31, CDB 35, CDB 41, and CDB 48) and three actinomycetes (CDA 16, CDA 19 and CDA 26) species significantly inhibited A. flavus. Among them CDB 35 (50 mm) and actinomycete CDA 19 (35 mm) showed significant zone of inhibition when compared to the rest of the isolates. To further evaluate and characterize the properties of strains all eight bacteria and three actinomycetes were screened against A. flavus by dual culture method on PDA, KB and GCY media to have the precise percent inhibition....

Acknowledgement: First of all, I would like to thank my major adviser, Dr. Farid Waliyar, for his sincere commitment, keen direction, unstinting support and understanding always given with a generous smile. It is an honour to be his student; and I greatly appreciate the large measure of freedom he gave me during the course of this work, which became the driving force that enabled me to work hard. Moreover, his excellent performance as a successful scientist and team leader at one of the regional centers of ICRISAT was the model on which I based my own work. I also acknowledge sincerely and thank Prof. Gopal Reddy, Head, Department of Microbiology, Osmania University for his constant support and encouragement. Words are not enough to explain his help throughout my Ph.D. tenure.....
