Marine Microorganisms and animals are gaining attention biotechnologically for the isolation of bioactive metabolites. An antagonistic marine microorganism was collected from Sundarban, mangrove forest of Bangladesh. The microorganism was identified on the basis of its morphological characteristics as Streptomyces species. It was grown in the yeast-extract glucose broth media at 37.5 C for 7 days for the production of bioactive metabolites. Antibacterial activity of ethyl acetate and chloroform extracts of the culture filtrate was performed against Bacillus subtilis and Escherichia coli....

The pathogenic microbes, with their determination to survive are gaining resistance by curious mechanisms and most of the effective antibiotics are becoming resistance due to in-discriminant use. As a result, microbial drug resistance is one of the most serious problems which the human-race is facing today. Beside this, new diseases like cancer and newer disease like AIDS are all around the world. So, medical scientists and researchers are searching for newer, safer and more effective and improved antibiotics to combat against drug resistance mutants as well as to combat newer diseases. The...
