In recent years the discovery of some most important antibiotic compounds obtained by fermenting environmental microbes has been reported, providing proof that isolation and fermentation of producer strains is a significant approach to decifer novel structural types of antibiotics. Whereas many microbial ...
Assertion (A): Antibiotics inhibit the growth of disease-causing bacteria. Reason (R): Antibiotics are obtained from different moulds. View Solution Antibiotics are mostly produced commercially from: View Solution Antibiotic flavicin is obtained from View Solution Antibiotics are obtained from View...
It was observed that results obtained with G-418 from Supplier A and Supplier B displayed wide variations on all measured parameters, including an inconsistency between the actual potency and the value reported on the supplied product literature. Discrepancies between re-tested potency values...
