海洋浮游植物是海洋食物网的初级生产者，是海洋有机质重要分泌者。海洋浮游植物光合作用产生的有机质,通过海洋细菌分泌的一系列胞外酶等将颗粒有机质POM（ParticleOrganicMatter,POM）进一步代谢为生物可利用的溶解有机质（BioavailableDissolvedOrganicMatter,BDOM）。在这一个过程中噬纤维菌-黄杆菌-拟杆菌(Cytophaga-Flavobacterium-Bacteroides,CFB)菌群起着重大的作用。这类细菌形态多样，一般具有较强的运动性和粘附性，能附着在大颗粒物质上生存，可以降解一般细菌难以利用的大分子有机质。从而削弱了基于浮游植物的沉...Marine phytoplankton, an important source of marine organic matter, is primary producers of the marine food web. Particle Organic Matter (POM), which is produced by marine phytoplankton photosynthesis, were further mineralized to bioavailable dissolved organic matter (BDOM) by marine bacteria through a series of secrete extracellular enzymes. In this process, Cytophaga - Flavobacterium - Bacteroid...学位：理学硕士院系专业：海洋与地球学院_海洋生物学学号：2232012115132
