Utilizing techniques of bioactive substances from tropical marine organisms (in 2007 the national scientific and technological progress second prize).

　　The project has used tropical marine living resources, isolated and identified 119 novel compounds including 72 bioactive compounds. The Pearl aminoglycoside preparation technology of specific range of molecule weigh, deodorization and detoxification of sea food using combination of column and membrane，preparation of chitin oligosaccharides specific range of molecule weigh, and usage of marine bioactive substance have been researched and developed.
