Roles and their interaction of each marine bacterial group in organic matter dynamics and aquatic ecosystem

为了更好地理解异养细菌在海洋环境中有机物动态中的作用，本文不仅讨论了整个细菌群落的能力，还讨论了群落中各细菌能力的多样性及其相互作用。细菌对有机物的多种降解能力及其共同作用可能是水生生态系统中有效转化和利用各种有机物的机制的基础。

To contribute to a better understanding of the roles of heterotrophic bacteria in organic matter dynamics in marine environments, not only the ability of whole bacterial community but also diversity of the ability of each bacteria in the community and their interaction were addressed. It was suggested that high variety of bacterial ability for organic matter degradation and their combined action might be a base of mechanisms to transform and utilize various organic matters efficiently in aquatic ecosystem.
