Ethanol fermentation in an immobilized cell reactor using Saccharomyces cerevisiae.
Fermentation of sugar by Saccharomyces cerevisiae, for production of ethanol in an immobilized cell reactor (ICR) was successfully carried out to improve the performance of the fermentation process. The fermentation set-up was comprised of a column packed with beads of immobilized cells. The immobilization of S. cerevisiae was simply performed by the enriched cells cultured media harvested at e...
متن کاملMethane from acetate.
The general features are known for the pathway by which most methane is produced in nature. All acetate-utilizing methanogenic microorganisms contain CODH which catalyzes the cleavage of acetyl-CoA; however, the pathway differs from all other acetate-utilizing anaerobes in that the methyl group is reduced to methane with electrons derived from oxidation of the carbonyl group of acetyl-CoA to CO...
متن کاملEffects of extracts derived from pistachio by-products on ruminal fermentation and methane production
The objective of this study was to evaluate the effects of different doses of pistachio by-product (PBP) extracts supplemented with alfalfa hay (AH) or barley grain (BG) on microbial fermentation in an in vitro fermentation system. The total extracted phenolic compounds were 36.96, 65.78, 67.02 and 8.85% and total extracted tannin contents were 37.11, 59.64, 56.87 and 7.55% when PBP was extract...
متن کاملSingle Step and Non-Catalytic Process for Formaldehyde Production from Methane using Microchannel Reactor: Theoretical Analysis
Conventionally, methane is reformed into syngas, and subsequently converted into C1-oxygenates (methanol and formaldehyde). A novel option is the catalyst-free single-step conversion of methane to C1-oxygenates. This study presents a comprehensive model of methane partial oxidation to formaldehyde as an intermediate chemical species in methane oxidation process using microreactor. The dependenc...
متن کاملInhibition of the fermentation of propionate to methane by hydrogen, acetate, and propionate.
Inhibition of the fermentation of propionate to methane and carbon dioxide by hydrogen, acetate, and propionate was analyzed with a mesophilic propionate-acclimatized sludge that consisted of numerous flocs (size, 150 to 300 mum). The acclimatized sludge could convert propionate to methane and carbon dioxide stoichiometrically without accumulating hydrogen and acetate in a propionate-minimal me...
