phototrophic bacteria การใช้

• Anaerobic phototrophic bacteria  among them " Chromatium okenii "  thrive between the two layers where they find the ideal conditions for their development.
• If sufficient sulfate is present to support sulfate reduction, the sulfide, produced in the sediments, diffuses upward into the anoxic bottom waters, where purple sulfur bacteria can form dense cell masses, called blooms, usually in association with green phototrophic bacteria.
• This enzyme catalyses the reduction of malonate semialdehyde to 3-hydroxypropionate, which is a key step in the 3-hydroxypropionate and the 3-hydroxypropionate / 4-hydroxybutyrate cycles, autotrophic CO 2 fixation pathways found in some green non-sulfur phototrophic bacteria and archaea, respectively.
• The precise relation of the " Thermotogae " to other phyla is debated ( " v . " bacterial phyla ) : several studies have found it to be deep-branching ( in Bergey's manual it appeared in fact in " Volume I : The Archaea and the deeply branching and phototrophic Bacteria " ), while other have found " Firmicutes " to be deep-branching with " Thermotogae " clustering away from the base.
