Diatom-diazotrophic cyanobacteria association as a major
photoautotrophPhotic volume in photobioreactors supporting ultrahigh population densities of the
photoautotroph Spirulina platensis.
That previously reported by (Ilyash, 2007) on widely used approach for the determination of efficient photosynthetic light reactions and the estimation of fluorescent parameters of
photoautotroph of marine micro algae.
But Desulfovibrio is not a
photoautotroph; it's a chemoautotroph.
prisca is thought to be derived from a marine
photoautotroph. The modern mat-forming cyanobacterium Entophysalis [21] (kingdom Monera) appears to be the morphologically nearest living organism to G.
CONTINUED EVALUATION OF THE EFFECTS OF WATER QUALITY IN THE SULPHUR FORK CREEK WATERSHED ON PERIPHYTON PRODUCTION AND
PHOTOAUTOTROPH PHOTOCHEMISTRY.
For example photosynthetic activities of aquatic organisms (
photoautotroph) in rice fields (anaerobic condition) are reduced by rice canopy.
"But no one really appreciated how this process could also be done by
photoautotrophs, such as these types of organisms that fix their own carbon and use light to make energy.
Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called
photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies all of the organic compounds and most of the energy necessary for life on Earth.
We assembled three experimental cultures (replicates), each containing a final volume of 525 mL: 500 mL of DOM (20.907 mg.[L.sup.-1] of organic carbon and 2.003 mg.[L.sup.-1] of dissolved organic nitrogen) and 25 mL of bacterial inoculum (4.8% of the final volume), which were maintained in the dark at 23 [+ or -] 1 [degrees]C to avoid the development of prokaryotic
photoautotrophs, and mixed twice a day to avoid anoxia.
They possess both chemoautotrophs and
photoautotrophs properties, allowing themselves to either utilizing light source or through oxidizing nutrient rich compound from their environment for their energy needs.
However, Cyanobacteria, which are key species in microbialite fabric formation (where they act as the main
photoautotrophs and diazotrophs), are the only lineage that did not show a phylogenetic structure, suggesting that different cyanobacterial lineages can contribute to microbialite formation and growth.
