摘要
从南海南部陆坡表层沉积物中扩增了细菌和古菌16S rDNA序列,并对克隆子文库进行系统发育分析。细菌序列以变形杆菌(Proteobacteria)居多,其次是浮霉菌(Planctomycete)、酸杆菌(Acidobacteria)和candidate division OP10,另外还有少量铁还原杆菌(Deferrobacteres)、candidate di-vision OP3、OP11、OP8、TM6、疣微菌(Verrucomicrobia)和螺旋体(Spirochaetes)。古菌序列分别来自泉古生菌(Crenarchaeota)和广古生菌(Euryarchaeota),以Marine Benthic Group B(MBGB)、Marine Crenarchaeotic GroupⅠ(MGⅠ)、Marine Benthic Group D(MBGD)和South African Gold Mine Eu-ryarchaeotic Group(SAGMEG)为主。少量序列为C3、甲烷杆菌(Methanobacteriales)和Novel Eu-ryarchaeotic Group(NEG)。结果表明海底表层沉积物中有丰富多样的微生物群落。
