Outline of Final Research Achievements

Streptomyces sp. strain 05, which isolated from deep-sea sediment, is capable to produce antimicrobial agent. This agent exhibits antimicrobial activity for methicillin-resistant Staphylococcus aureus (MRSA), which is famous for the drug-resistant bacteria. We achieved to get the purified substance by some steps. By some analytical methods such as nuclear magnetic resonance method, IR spectroscopy and accurate mass analysis, this substance is a macrolide antibiotic, possesses polyol structure with acetyl-ester group, methoxy group and methyl group. Additionary, from analysis of antibacterial spectrum, this agent effects against the vancomycin resistant enterococcus. Therefore, it is hoped that this substance is developed to a novel antimicrobial agent against multiple-drug-resistant bacteria.
