摘要
利用特异性培养基对采自宁波象山地区养殖虾池底泥样品进行富集、分离和纯化,得到了一株紫色非硫细菌(PNSB),依据形态特征观察、无机碳源利用、活细胞吸收光谱测定、pufM基因检测及16S rRNA基因序列分析等实验,初步鉴定其为comamonadaceae科中一新属.
A strand of purple non-sulfur bacteria(PNSB) is isolated from sediment of a shrimp pond in Xiangshan, Ningbo. Judging by several factors such as the cell morphologic structure, culture characteristics, inorganic carbon utilization, the absorb spectrum of living cells and PCR detection of pufM gene, the sample is identified as a strand of anoxygenic anaerobic phototrophic bacteria. Analysis of the 16S rRNA gene sequences reveal that the isolate identified in the experiment should be classified as a new genus of the family comamonadaceae.
