1. Electrically enhanced ethanol fermentation by Clostridium thermocellum and Saccharomyces cerevisiae

Author:
Shin, H.S.; Zeikus, J.G.; Jain, M.K.

ethanol fermentation,   etc   ; Clostridium thermocellum; Saccharomyces cerevisiae; acetates; bioreactors; electric current; electrochemistry; ethanol production; metabolites;     Show all 9 Subjects
Abstract:
... Ethanol production by Clostridium thermocellum ATCC 35609 and Saccharomyces cerevisiae ATCC 26603 was improved in an electrochemical bioreactor system. It was increased by 61% with Cl. thermocellum and 12% with S. cerevisiae in the presence of -1.5 V of electric potential. These increases were attributed to high production rates due to regeneration and availability of increased reduced equivalents ...

Abstract:
... A Strain of host yeast YF207, which is a tryptophan auxotroph and shows strong flocculation ability, was obtained from Saccharomyces diastaticus ATCC60712 and S. cerevisiae W303-1B by tetrad analysis. The plasmid pGA11, which is a multicopy plasmid for cell-surface expression of the Rhyzopus oryzae glucoamylase/alpha-agglutinin fusion protein, was then introduced into this flocculent yeast strain ...

Abstract:
... A flocculent Saccharomyces cerevisiae strain secreting Aspergillus niger beta-galactosidase activity was constructed by transforming S. cerevisiae NCYC869-A3 strain with plasmid pVK1.1 harboring the A. niger beta-galactosidase gene, lacA, under the control of the ADH1 promoter and terminator. Compared to other recombinant S. cerevisiae strains, this recombinant yeast has higher levels of extracell ...

Abstract:
... Several bottlenecks in the alcoholic fermentation process must be overcome to reach a very high and competitive performance of bioethanol production by the yeast Saccharomyces cerevisiae. In this paper, a nutritional strategy is described that allowed S. cerevisiae to produce a final ethanol titre of 19% (v/v) ethanol in 45 h in a fed-batch culture at 30°C. This performance was achieved by impleme ...

fermentation,   etc   ; Saccharomyces cerevisiae; genes; glucose; glucose transporters; xylitol; xylose;     Show all 7 Subjects
Abstract:
... Zero trans-influx assays of glucose and xylose were performed using Saccharomyces cerevisiae to investigate transport characteristics under high and low glucose conditions. Under high glucose conditions, most glucose was transported by the low-affinity transporter. The high-affinity transporter was expressed under low glucose conditions, transporting over 50% glucose. Inhibition kinetics revealed ...
