Uncovering the ecological role of photoheterotrophic bacteria in the ocean is one of the main accomplishments of marine microbiology of the past decade. Marine photoheterotrophs include two main groups: Aerobic anoxygenic phototrophic (AAP) bacteria and proteorhodopsin (PR)-containing bacteria. These organisms make up large fractions of the microbial communities inhabiting the euphotic zone of world`s oceans. In spite of similar metabolisms, AAP and PR-containing bacteria differ in their photochemistry, physiology, and ecology. The ability to use light energy appears to allow more economical utilization of dissolved organic matter, which implies that photoheterotrophic bacteria may play a unique role in the microbial carbon pump
