In this study, yeast and acetic acid bacteria strains were adopted to enhance the ethanol-type fermentation resulting to a volatile fatty acids yield of 30.22 g/L, and improve acetic acid production to 25.88 g/L, with food wastes as substrate. In contrast, only 12.81 g/L acetic acid can be obtained in the absence of strains.

Initial acetic acid can improve the ethanol oxidation rate of acetic acid bacteria for acetic acid fermentation. In this work, Acetobacter pasteurianus was cultured in ethanol-free medium, and energy production was found to increase by 150% through glucose consumption induced by initial acetic acid.

Acetobacter pasteurianus strains IFO3283, SKU1108, and MSU10 were grown under acetic acid fermentation conditions, and their growth behavior was examined together with their capacity for acetic acid resistance and pellicle formation. In the fermentation process, the cells became aggregated and covered by amorphous materials in the late-log and ...

Production of acetic acid in packed bed fermenters
Biotechnology Letters, 1988Production of acetic acid from ethanol byAcetobacter aceti attached to a variety of support materials has been examined in fixed-film packed bed fermenters. Overall batch acid productivities with triangular ceramic particles and nylon mesh were respectively 56% and 30% greater than that for woodshavings, with comparable high acid yields.

Acetic acid bacteria (AAB) are obligate aerobes that belong to the α-Proteobacteria and are used for industrial vinegar production because of their remarkable ability to oxidize ethanol by alcohol dehydrogenase, aldehyde dehydrogenase, and terminal oxidase of respiratory chain members on the cell membrane.

Simultaneous Saccharification and Fermentation of Cellulosic Biomass to Acetic Acid
Applied Biochemistry and Biotechnology, 2000A strain of Clostridium thermoaceticum (ATCC 49707) was evaluated for its homoacetate potential. This thermophilic anaerobe best produces acetate from glucose at pH 6.0 and 59 degrees C with a yield of 83% of theoretical. Enzyme hydrolysis of two substrates, a-cellulose and a pulp mill sludge, yielded 68% and 70% digestion, respectively.

Mathematical model for liquid-gas equilibrium in acetic acid fermentations
Biotechnology and Bioengineering, 1998An experimental study was conducted to propose an adequate mathematical model for liquid-gas equilibrium in acetic acid fermentations. Three operation scales (laboratory, pilot plant, and industrial plant) were employed to obtain the sets of experimental data. The proposed model, based in the UNIFAC method for the estimation of activity coefficients of

Anaerobic thermophilic fermentation for acetic acid production from milk permeate
Journal of Biotechnology, 2000Fermentation of milk permeate to produce acetic acid under anaerobic thermophilic conditions (approximately 60 degrees C) was studied. Although none of the known thermophilic acetogenic bacteria can ferment lactose, it has been found that one strain can use galactose and two strains can use lactate.

Improving fermentation performance of recombinant zymomonas in acetic acid-containing media
Applied Biochemistry and Biotechnology, 1998In the production of ethanol from lignocellulosic biomass, the hydrolysis of the acetylated pentosans in hemicellulose during pretreatment produces acetic acid in the prehydrolysate. The National Renewable Energy Laboratory (NREL) is currently investigating a simultaneous saccharification and cofermentation (SSCF) process that uses a proprietary ...
