Yeast sulfate-reducing system. I. Reduction of sulfate to sulfite.
X35-APS-This substrate was synthesized from S%ulfur trioxide-pyridine complex and AMP by a method similar to that of Baddiley et al. (13) except for simplifications and modifications necessary for introduction of label. An alternat,ive method has been described by Reichard and Ringertz (14). Approximately 3.7 me of S35-HzS04 was dried at 80” in a reaction tube fitted with a ball joint and side ...
متن کاملCell-Free Sulfate-Reducing System from Chlorellal
A cell-free system from Chlorella pyrenoidosa Chick (Emerson strain 3) which produces acid-volatile radioactivity from 35SO42is described. A high speed supernatant from cells broken in the French Press at pH 7.0 shows maximal activity when fortified with ATP, an ATP-generating system (creatine phosphate and creatine phosphokinase), TPN, a TPNreducing system (glucose-6-phosphate and glucose-6-ph...
متن کاملDistinguishing iron-reducing from sulfate-reducing conditions.
Ground water systems dominated by iron- or sulfate-reducing conditions may be distinguished by observing concentrations of dissolved iron (Fe(2+)) and sulfide (sum of H(2)S, HS(-), and S(=) species and denoted here as "H(2)S"). This approach is based on the observation that concentrations of Fe(2+) and H(2)S in ground water systems tend to be inversely related according to a hyperbolic function...
متن کاملSimultaneous Electricity Generation and Sulfur Removal by Electrogenic Sulfate Reducing Bacteria in BES System
The modern BioElectrochemical technologies can convert the energy stored in the chemical bonds of biodegradable organic materials to renewable electrical energy through the catalytic reactions of microorganisms while treating the waste waters. The present research was conducted to evaluate the efficiency of a single-chamber Bioelectrochemical system with the carbon aerogel catalyst, as a simple...
متن کاملMetabolic Flexibility of Sulfate-Reducing Bacteria
Dissimilatory sulfate-reducing prokaryotes (SRB) are a very diverse group of anaerobic bacteria that are omnipresent in nature and play an imperative role in the global cycling of carbon and sulfur. In anoxic marine sediments sulfate reduction accounts for up to 50% of the entire organic mineralization in coastal and shelf ecosystems where sulfate diffuses several meters deep into the sediment....
