Abstract

The full genome sequence of Ectothiorhodospira sp. strain BSL-9 is reported here. This purple sulfur bacterium encodes an arxA-type arsenite oxidase within the arxB2AB1CD gene island and is capable of carrying out "photoarsenotrophy" anoxygenic photosynthetic arsenite oxidation. Its genome is composed of 3.5 Mb and has approximately 63% G+C content.

摘要

本文报道了嗜硫外硫红螺菌(Ectothiorhodospira sp.)菌株BSL-9的全基因组序列。这种紫色硫细菌在arxB2AB1CD基因岛内编码一种arxA型亚砷酸盐氧化酶,能够进行“光砷营养”——无氧光合亚砷酸盐氧化。其基因组由350万个碱基对组成,G+C含量约为63%。
