Complete genome sequence of bacteriochlorophyll-synthesizing bacterium Porphyrobacter neustonensis DSM 9434

Abstract The genus Porphyrobacter belongs to aerobic anoxygenic phototrophic bacteria cluster. Porphyrobacter neustonensis DSM 9434 was isolated from a eutrophic freshwater pond in Australia, and is able to synthesize Bacteriochlorophyll a as well as grow under aerobic conditions. It is the type species of the genus Porphyrobacter. Here we describe the characteristics of the strain DSM 9434, including the genome sequence and annotation, synthesis of BChl a, and metabolic pathways of the organism. The genome of strain DSM 9434 comprises 3,090,363 bp and contains 2,902 protein-coding genes, 47 tRNA genes and 6 rRNA genes. Strain DSM 9434 encodes 46 genes which participate in BChl a synthesis and this investigation shed light on the evolution and functional implications regarding bacteriochlorophyll synthesis.
