Abstract：Novel species， novel genes， novel structures， and novel mechanisms of marine microbes are expected to be achieved to raise the Chinese scientific research level of secondary metabolites from marine microorganisms. This comprehensive project is an interdisciplinary cooperation of frontier sciences. Marine microorganisms are the most advantageous and special marine biological resources. Research on marine microorganisms is linked with security of national marine living resources， innovative drugs， ecological safety and major scientific strategy of our country. Secondary metabolites of marine microorganisms are not only the foundation of innovative medicines and ecological restoration， but also the starting point for the combinatorial biosynthesis. Combinatorial biosynthesis technology will pave a new way of a healthy， rapid and harmonious development of marine microorganisms industry. Concentrating on the key scientific issue，" unique secondary metabolic process and biological significance of marine microorganisms"， microbial community from marine environment of China was selected. We focus on the diversity of species and heredity， unique characteristics of marine ecosystems， physiological and ecological effects on the novel secondary metabolites of marine microbiology， secondary metabolites related genes， and regulatory mechanism of biosynthesis pathways. Based on DNA recombinant technology， metabolic engineering， and biosynthesis theory， combinatorial biosynthesis technology was developed， and will help to lay a foundation for the development of innovative medicines and environmentally friendly products.
