Abstract：Marine microorganisms，are emerging as ideal resources for discovering new taxa and new secondary metabolites. Encouraging from our solid research data accumulated previously， we aim in this project to continuously isolate and identify new metabolites and to demonstrate their functions， such as antimicrobial， anti-fouling and anti-tumor， etc. In addition， we aim to elucidate the biosynthetic gene clusters so as to reveal their biosynthetic mechanisms and pathways， to enhance their structural diversity via combinatorial biosynthesis. The ultimate goal of this project is to provide a basis for discovering lead compounds with pharmaceutical potential.

Key Words：Marine microbiology； Secondary metabolites； Diversity； Functional studies
