Whole-Genome Sequence of a Freshwater Aerobic Anoxygenic Phototroph, Porphyrobacter sp. Strain AAP82, Isolated from the Huguangyan Maar Lake in Southern China

Abstract
The Porphyrobacter genus (of the class Alphaproteobacteria ) contains aerobic anoxygenic phototrophic species. Here we report a draft genome sequence of a freshwater bacterium, Porphyrobacter sp. strain AAP82. It contains a 38-kb-long photosynthesis gene cluster, but carbon-fixation genes are absent. The presence of respiratory enzymes, tricarboxylic acid (TCA) cycle, and the Entner-Doudoroff pathway demonstrates its aerobic photoorganotrophic character.
