Nitrate Reduction and Assimilation in Chlorella
1. Nitrate reduction and assimilation have been studied in Chlorella pyrenoidosa under growth conditions by observing effects on the CO(2)/O(2) gas exchange quotient. 2. During assimilation of glucose in the dark, nitrate reduction is noted as an increase in the R.Q. to about 1.6 caused by an increased rate of carbon dioxide production. 3. During photosynthesis at low light intensity nitrate re...
متن کاملRole of molybdenum in nitrate reduction by chlorella.
Molybdenum is absolutely required for the nitrate-reducing activity of the nicotinamide adenine dinucleotide nitrate reductase complex isolated from Chlorella fusca. The whole enzyme nicotinamide adenine dinucleotide nitrate reductase is formed by cells grown in the absence of added molybdate, but only its first activity (nicotinamide adenine dinucleotide diaphorase) is functional. The second a...
متن کاملNitrate Storage and Dissimilatory Nitrate Reduction by Eukaryotic Microbes
The microbial nitrogen cycle is one of the most complex and environmentally important element cycles on Earth and has long been thought to be mediated exclusively by prokaryotic microbes. Rather recently, it was discovered that certain eukaryotic microbes are able to store nitrate intracellularly and use it for dissimilatory nitrate reduction in the absence of oxygen. The paradigm shift that th...
متن کاملDissimilatory nitrate reduction by Propionibacterium acnes.
Propionibacterium acnes P13 was isolated from human feces. The bacterium produced a particulate nitrate reductase and a soluble nitrite reductase when grown with nitrate or nitrite. Reduced viologen dyes were the preferred electron donors for both enzymes. Nitrous oxide reductase was never detected. Specific growth rates were increased by nitrate during growth in batch culture. Culture pH stron...
متن کاملFucosterol Reduction to Clionasterol in vivo by Chlorella ellipsoidea.
In the past few years, rapid strides have been made in our knowledge of the origin of the extra methyl and ethyl groups in the side chain of plant sterols. It now appears that desmosterol (3) (fig 1) or another A24 sterol is the recipient of a methyl group from S-adcenosyl methionine resulting in the formation of 24-methylene cholesterol (III) which is the receptor of another methyl group to fo...
