The bacterial diversity of the continental shelf sediment in the Yellow Sea was investigated by the cloning and sequencing of PCR-amplified 16S rRNA genes. The majority of the cloned sequences were distinct phylotypes that were novel at the species level. The richness estimator indicated that the sediment sample might harbor up to 32 phylum-level taxa. A large number of low-abundance, phylum-level taxa accounted for most of the observed phylogenetic diversity at our study site, suggesting that these low-abundance taxa might play crucial roles in the shelf sediment ecosystem.
通过对黄海大陆架沉积物中 PCR 扩增的 16S rRNA 基因进行克隆和测序，研究了该地区的细菌多样性。大多数克隆序列是在种水平上新颖的独特的系统发育类型。丰富度估计表明，该沉积物样本可能含有多达 32 个门水平的分类群。大量低丰度的门水平分类群占据了我们研究地点观察到的大部分系统发育多样性，这表明这些低丰度分类群可能在大陆架沉积物生态系统中发挥着关键作用。
