Enzymes catalyzing the scavenging of reactive oxygenic
species (ROS) play an important role in tissue salt tolerance (Roy et al.
There are two pigment-protein complexes that orchestrate the primary reactions of light in oxygenic
photosynthesis: photosystem I and photosystem II.
Other less obvious roles make carotenoids essential components in oxygenic
In the Photosynthesis exhibit, visitors can contemplate several cultures of oxygenic
phototrophic bacteria in plastic Petri dishes.
Hypoxia may increase aspects of sulfide cycling, especially by decreasing the importance of oxygenic
decomposition reactions while increasing the importance of anaerobic reactions such as sulfate reduction and sulfide production.
The complex architecture of oxygenic
Cyanobacteria are the oxygenic
photosynthetic prokaryotes that occur worldwide in a range of terrestrial, fresh water and marine environment .
1999, 2-methyl hopanoids as biomarkers for cyanobacterial oxygenic
photosynthesis: Nature, v.
The enormous rise in atmospheric oxygen concentration about 2500 million years ago, presumably due to oxygenic
photosynthesis, led to a decline of anaerobes, which survived by occupying residual niches with a low concentration of oxygen (Kasting, 2001; Anbar and Knoll, 2002; Catling et al, 2005; Kerr, 2005).
Most composting methods rely on the bio-chemical processes of aerobic or oxygenic
bacteria and fungi (there is also a method that relies on anaerobic or non-oxygenic
organisms that thrive in decaying organic materials).
The algae refer to a large and diverse assemblage of eucaryotic organisms that contain chlorophyll and carry out oxygenic
Some yin-promoters have been shown to facilitate myocardial metabolism, enhance hypoxia tolerating capacity, decrease oxygen consumption, increase artery-vein blood oxygenic
pressure difference and coronary blood flow, and maintain ATP as well as glucagon content in hypoxia myocardium at a comparably high level.
