Comments "Photoheterotrophic microbes include the proteorhodopsin (PR)-based phototrophic (PRP) bacteria and the aerobic anoxygenic phototrophic (AAP) bacteria... Proteorhodopsin is carried by 15% to > 70% of all bacteria in surface waters, depending on the oceanic region and detection method (BNID 111293). AAP bacteria are also abundant, albeit not at the levels seen for PRP bacteria, contributing 1% to as much as 30% of all bacteria in the surface ocean (primary source)."
