The photoheterotrophy is the capacity to use both organic substrates and light energy. The aerobic anoxygenic phototrophic bacteria (AAPB), the proteorhodopsin-containing bacteria (PRB) and the picocyanobacteria (Synechococcus) practice it. Increases in organic carbon exported by rivers and in expos...
