Aerobic anoxygenic photoheterotrophic bacteria (AAPB), also named aerobic anoxygenic photoheterotrophs (AAPs), is a group of bacteria that are primarily heterotrophic but can utilize light energy through bacterial chlorophyll a.〔Nianzhi Jiao, Gerhard J. Herndl, Dennis A. Hansell, Ronald Benner, Gerhard Kattner, Steven W. Wilhelm, David L. Kirchman, Markus G. Weinbauer, Tingwei Luo, Feng Chen, Farooq Azam (2010). "Microbial Production of Recalcitrant Dissolved Organic Matter: Long-term Carbon Storage in the Global Ocean". ''Nature Reviews Microbiology'' 8, 593-599. dio: 10. 1038/nrmicro2386〕 == Description == In contrast to other known anoxygenic phototrophs, these microbes are obligatory aerobes: They metabolize carbon and other organic substrates and use O2-dependent respiration, but they also contain bacteriochlorophyll a, carotenoids, as well as photosynthetic reaction centers and light-harvesting complexes. Although the amount of bacteriochlorophyll in these photoheterotrophs is lower than in other photosynthetic bacteria, they are capable of fixing CO2 during photosynthesis, and light enhances their growth. Their ancestors appear to be purple nonsulfur bacteria, and they have arisen independently several times during evolution. So far, they have not attracted much attention, although they are abundant in organic-rich sediments (on the surface of seaweeds) and in seawater.〔Tom Fenchel (2001). "Marine Bugs and Carbon Flow".
