Bacteria anoxygenic

Fractionation also occurs during processes in the oxidative part of the sulfur cycle. Sulfide oxidation, which is pervasive in marine enviromnents (for example, 90% or more of the sulfide produced during sulfate reduction in coastal sediments are reoxidized) includes various processes, which are all associated with inverse isotope fractionation effects. These processes include the phototrophic oxidation by a variety of anoxygenic bacteria (-2 to 0%o), the non-phototrophic oxydation (up to -18%o), and the already mentioned disproportionation of sulfur compounds with intermediate oxidation states as... [Pg.358]

Flowever, many photosynthetic bacteria, such as purple sulfur and green sulfur bacteria contain special bacteriochlorophyll compounds (not chlorophyll a) and carry out anoxygenic photosynthesis without producing oxygen ... [Pg.35]

Modem layered microbial communities provide a view into biochemical redox cycling. Oxidation of Fe(ll) through high O2 contents generated by cyanobacteria generally occurs in the top most (photic) portions of microbial mats. The upper, near-surface layers of microbial mats that are rich in cyanobacteria are commonly underlain by purple and green anoxygenic photosynthetic bacteria that thrive in the IR photic spectra (Stahl et al. 1985 Nicholson... [Pg.361]

By interesting coincidence, the old dogma that cytochromes are not present in anaerobes was demolished by discovery, at about the same time, of c-type cytochromes in Desulfovibrio and anoxygenic photosynthetic bacteria (Kamen and Vernon 1955). [Pg.5]
