利用0.2和0.1 μ m孔径过滤器捕获的708个热液喷口原核生物克隆，共构建了11个16S rRNA基因文库，包括34个古细菌和72个细菌种型。古菌群和细菌群分别以绿古菌群和变形菌群为主。新的无亲缘关系的种型仅出现在0.1 μ m捕获种群中。
Eleven 16S rRNA gene clone libraries including 34 archaeal and 72 bacterial phylotypes were constructed from total 708 clones of hydrothermal vent prokaryotes trapped by 0.2- and 0.1-mu m-pore-size filters. Crenarchaeota and Proteobacteria phylotypes dominated the archaeal and bacterial populations, respectively. Novel unaffiliated phylotypes occurred only in the 0.1-mu m-trapped populations.
