Abstract

Abstract

The diversities of genes specific for dissimilatory sulfite reductase(DSR) and methyl coenzyme Mreductase MCR in metagenomic DNA of deep sediment of the West Pacific warm pool were studied by PCR RFLP using primers specific for dsrAB and mcr A,respectively.The results showed that the dsrA B in the sample were come from 6 genus of δ-Proteobacteria,mainly Desulfovibrio and Desulf obacter.All of the mcrA in the sample were come from archaeal methanogens,mainly Met hanomicrobia.These genes were tend to clustered within independent clades on phylogenetic tree respectively.Fur thermore,many dsr AB and mcr A genes showed high similarity to those from unknown or new species.These results indicated that the microbial metabolisms,which may include some new metabolic pathway,were active in the Sand CH₄ cycles in deep sediment of "warm pool".
