Cathodes as electron donors for microbial metabolism: which extracellular electron transfer mechanisms are involved?
This review illuminates extracellular electron transfer mechanisms that may be involved in microbial bioelectrochemical systems with biocathodes. Microbially-catalyzed cathodes are evolving for new bioprocessing applications for waste(water) treatment, carbon dioxide fixation, chemical product formation, or bioremediation. Extracellular electron transfer processes in biological anodes, were the...
متن کاملReactions of Organoaluminium Compounds with Electron Donors
The application of organoaluminium compounds as components of organometallic or complex systems is connected with a knowledge of their reactions with electron donors. Reactions with nitriles, ketones, esters, ethers, alkyl chlorides, vinyl chloride, and acid chlorides as the electron donors were investigated. The first stage of the reaction of an organoaluminium compound with an electron donor ...
متن کاملRecent development of reactions with alpha-diazocarbonyl compounds as nucleophiles.
The nucleophilic addition reaction of diazo-compound derived anions or enolates with electrophilic C=O and C=N bonds have been summarized. The subsequent reactions of the addition products demonstrate diverse reactivities of the diazocarbonyl compounds bearing other functional groups and their potential in organic synthesis. Asymmetric catalysis is also possible with diazocarbonyl compounds as ...
متن کاملSources of Betaine as Methyl Group Donors in Broiler Diets
Betaine is donor of methyl groups and can partially replace methionine in diets for this purpose. The objective of this study was to evaluate three sources of betaine in partial substitution of methionine supplement in broiler diets. The Cobb-500 broiler chickens were allocated in a completely randomized experimental design with 5 treatments and 7 replicates of 49 birds each. The positive contr...
متن کاملPhysical Triplet Quenching by Electron Donors
Absolute radical yields, as determined by flash spectroscopy, are reported for the reaction of the thionine triplet 3TH+ and its protonated form 3TH2++ with a variety of electron donors in methanolic solution. The different yields, extrapolated to infinite donor concentrations, are due to partial physical quenching of the triplets in the electron transfer reaction. The results are indicative of...
