Members of the cfb ( cytophaga - flexibacter - bacteroides ) were found to be rich in upper sediment of " warm pool " while they were not detected in sediment from " manganese nodule " area , which indicated that there were more organic substances in the " warm pool " area
除了紫細(xì)菌之外， cfb類群在“暖池”區(qū)沉積物中也是一類較重要的細(xì)菌，主要集中在表層沉積物；而在“結(jié)核”區(qū)沒(méi)有檢測(cè)到屬于cfb類群的細(xì)菌，表明“暖池”區(qū)表層存在較多的有機(jī)物。
In the sediment , bacteria belonging to the cfb ( cytophaga - flexibacter - bacterioides ) group and the - proteobacteria , - proteobacteria were the main groups . the 16s rdna diversity of 7th layer was different from that of other layers , including the analysis of rflp , gene type and the population of cfb group . and the population of - proteobacteria showed inverse ratio with that of cfb group
基于以上的試驗(yàn)，我們分析了企鵝糞便沉積物中微生物生態(tài)與環(huán)境變化和環(huán)境污染的關(guān)系并提出了沉積物中出現(xiàn)的異常在環(huán)境和氣候方面可能的解釋，初步建立了以分析企鵝糞便沉積物中微生物多樣性為手段的新的考察南極氣候變遷和環(huán)境污染的思路。
