利用对珠江河口沉积物中细菌16S rRNA基因的变性梯度凝胶电泳分析来表征细菌群落组成。对切下条带的测序分析表明革兰氏阴性菌……
Bacterial community compositions were characterized using denaturing gradient gel electrophoresis analysis of bacterial 16S rRNA gene in the sediments of the Pearl River estuary. Sequencing analyses of the excised bands indicated that Gram-negative bacteria, especiallyGammaproteobacteria, were dominant in the Pearl River estuary. The diversity of polycyclic aromatic hydrocarbon ring-hydroxylating dioxygenase (PAH-RHD) gene in this estuary was then assessed by clone library analysis. The phylogenetic analyses showed that all PAH-RHD gene sequences of Gram-negative bacteria (PAH-RHD[GN]) were closely related to thenagAcgene described forRalstoniasp. U2 ornahAcgene forPseudomonassp. 9816–4, while the PAH-RHD gene sequences of Gram-positive bacteria (PAH-RHD[GP]) at sampling site A1 showed high sequence similarity to thenidAgene fromMycobacteriumspecies. Meanwhile, molecular diversity of the two functional genes was higher at the upstream of this region, while lower at the downstream. Redundancy analysis indicated that environmental factors, such as NH4-N, ∑PAHs, pH, SiO3-Si, and water depth, affected the distribution of the PAH-RHD[GN]gene in the Pearl River estuary.
