Mussel Periostracum from Deep-Sea Redox Communities as a Microbial Habitat: 3. Secondary Inhabitants     

James E.  Hook Stjepko  Golubic 《Marine Ecology》1992,13(2):119-131

Abstract. Vacated microborings in periostracum of live mussels of the Florida Escarpment redox community (depth of 3266 m) become a habitat for a prolific secondary microbiota consisting of a variety of prokaryotic and a few eukaryotic organisms. Periostracum surface is also colonized by diverse microorganisms, dominated by presumed chemolithotrophic bacteria with stacks of intracellular lamellae. Unlike sheltered microflora within borings, the surface community is heavily grazed upon by numerous archaeogastropods and ciliates.  相似文献

微生物自养固碳是维持干旱区土壤微生物群落结构及异养活动的重要过程,并影响地表生物结皮的演替及生态功能。近年来,土壤微生物组学的广泛应用,拓展了蓝细菌及真核藻类土壤自养微生物功能群研究,揭示了非蓝细菌类原核微生物向土壤输入有机质的可能。基于此,本文综述了干旱区土壤蓝细菌及藻类的分布及功能特征,并总结了环境因子的调控作用,重点总结了近几年对非蓝细菌自养微生物功能群及其生态功能的探索,最后对干旱区土壤自养微生物功能群研究的发展进行了总结与展望,以期为深入理解干旱区土壤微生物群落的形成及发展机理提供理论基础,并为良好生物结皮的构建提供科学依据。  相似文献
