The research on diversity is the key point for exploring and exploiting marine microbial resources. Giving attention to species diversity and genetic diversity of marine microbes, discovering novel metabolites with multiple functions, revealing key secondary metabolic process and the main regulation mechanisms in marine microbes, and developing a new technology of biosynthesis, are the important foundation for discovering innovative drugs and developing functional products with characteristics. The present paper has reviewed the recent advances in the four research areas of marine microbial species diversity, genetic diversity, chemical diversity and metabolic diversity in China.展开更多

From the methodological point of view, there were analyzed the different aspects that causes the present crisis in this territorial contest and that, contextually, at the same time, prevent its recovery. The procedural pathway followed these steps： analysis, synthesis, comparison, deduction and induction. The results showed that there are technical, social, environmental, political and infra-structural aspects that cause this stated economical emergency for the compartment. A ＂new rural paradigm＂, in particular, the multi-functionality of the farm seems to be the road to the progress of mountain regions.
