Apart from these 3 colors, all other surfaces revealed the presence of fungi and phototrophs (algae and, mainly, cyanobacteria).
This anoxygenic phototroph might even assist cyanobacteria by consuming sulfide after sunrise and thus relieving sulfide inhibition of oxygenic photosynthesis.

The incubation temperature was 15[degrees]C except for the specific vibrio enrichments, which were incubated at 37[degrees]C for 7 and 18 h, and the phototroph enrichments, which were incubated at room temperature.
With the algae's nuclei, phototrophs also acquire the instructions to do such things as make more chloroplasts, synthesize different pigments, and optimize chloroplasts' ability to perform at different light levels.
If they get their energy from light through photosynthesis they are phototrophs. If they get their energy from oxidizing organic and inorganic molecules they are chemotrophs.
