【摘要】 采用透射电子显微镜对我国南海细薄星芒海绵体内微生物的分布进行了观察研究,同时结合海绵的结构特点与摄取营养的方式对分布特点进行了分析讨论。研究证明:在细薄星芒海绵体内除骨骼外的细胞间中质层、细胞内、海绵内腔等部位均分布着形态多样的微生物,其中海绵中质层是共(寄)生微生物最为丰富的地方。海绵微生物的分布特点与海绵腔状多孔的结构以及依靠过滤海水获取营养的方式有关,这对于将来揭示微生物在海绵体内的聚集机制及其与环境的关系具有重要价值。更多还原

【Abstract】 In this paper,the distribution of sponge Stelletta tenui associated microorganisms was investigated by transmission electron microscope and the characteristics were discussed on the basis of sponge structure and nutrition ingestion. It was proved that there are abundant microorganisms in sponge mesohyl,sponge cells and the inner cavity except for the sponge bone,in which sponge mesohyl is the main site for symbiotic microorganisms.It was suggested that the microbial distribution characteristics are due to the cavity structure and the nutrition ingestion of sponge by water filtration to some extent, which is useful for us to understand the mechanism of microbial accumulation in sponge and the relationship between sponge associated microorganisms and the water environment in the future.更多还原
