In their study, published in February 2016 in Ecology Letters, the research team showed that acquired phototrophs can have a dramatic impact on the dynamics of marine microbial communities, causing a series of boom-and-bust cycles.
The phototrophs colonizing such substrates are mainly composed of filamentous cyanobacteria and cocoidal bacteria (Scheerer et al.

Coralline algae are the only carbonate-secreting phototrophs in this depositional system, and can sometimes produce carbonate banks up to a few metres in height.
The concentration of sources of reducing power used by phototrophs was progressively diminished.

The samples included phototrophs, which convert sunlight into usable energy, and mixotrophs, which can use sunlight or consume dead organic matter.
Life exists in two major forms: phototrophs and chemotrophs.
The phototrophs and chemotrophs (collectively called autotrophs) use energy sources that are inorganic (sunlight and chemical energy respectively), whereas heterotrophs acquire their energy by consuming organics (see Table 2).
If they get their energy from light through photosynthesis they are phototrophs.
They have been seen in denitrifyers, sulfate reducers, iron reducers, phototrophs, and methanogenic consortia (Beller and Edwards 2000; Beller et al.
