Acetic acid formation in escherichia coli fermentation

Biotechnology and Bioengineering, 1992
AbstractAcetic acid formation in Escherichia coli fermentation has been studied in continuous cultures. Experimental results suggest that the limited capacity of the oxidative metabolism (perhaps the limited capacity of TCA cycle) may be responsible for acetic acid formation.

Hydrogen production by fermentation using acetic acid and lactic acid

Journal of Bioscience and Bioengineering, 2007
Microbial hydrogen production from sho-chu post-distillation slurry solution (slurry solution) containing large amounts of organic acids was investigated. The highest hydrogen producer, Clostridium diolis JPCC H-3, was isolated from natural environment and produced hydrogen at 6.03+/-0.15 ml from 5 ml slurry solution in 30 h.

Effect of Acetic Acid on Citric Acid Fermentation in an Integrated Citric Acid–Methane Fermentation Process

Applied Biochemistry and Biotechnology, 2014
An integrated citric acid-methane fermentation process was proposed to solve the problem of extraction wastewater in citric acid fermentation process. Extraction wastewater was treated by anaerobic digestion and then recycled for the next batch of citric acid fermentation to eliminate wastewater discharge and reduce water resource consumption.

Impact of acetic acid in methane production from glycerol/acetic acid co-fermentation

International Journal of Hydrogen Energy, 2019
Abstract Co-fermentation of glycerol and acetic acid in anaerobic digestion was set up to generate biogas in batch reactors under mesophilic condition, pH 7. The experiments were varied COD ratios of glycerol and acetic acid were varied with the total combined COD of 5,20 0 mg/L.

Fermentation of Xylose into Acetic Acid by Clostridium thermoaceticum

Applied Biochemistry and Biotechnology, 2001
For optimum fermentation, fermenting xylose into acetic acid by Clostridium thermoaceticum (ATCC 49707) requires adaptation of the strain to xylose medium. Exposed to a mixture of glucose and xylose, it preferentially consumes xylose over glucose. The initial concentration of xylose in the medium affects the final concentration and the yield of acetic ...

Genetic organization ofAcetobacter for acetic acid fermentation

Antonie van Leeuwenhoek, 1994
Plasmid vectors for the acetic acid-producing strains of Acetobacter and Gluconobacter were constructed from their cryptic plasmids and the efficient transformation conditions were established. The systems allowed to reveal the genetic background of the strains used in the acetic acid fermentation.

Proteome analysis of Acetobacter pasteurianus during acetic acid fermentation

Journal of Proteomics, 2012
Acetic acid bacteria (AAB) are Gram-negative, strictly aerobic microorganisms that show a unique resistance to ethanol (EtOH) and acetic acid (AcH). Members of the Acetobacter and Gluconacetobacter genera are capable of transforming EtOH into AcH via the alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) enzymes and are used for the ...

Inhibitory effect of acetic acid on dark-fermentative hydrogen production

Bioresource Technology, 2022
This study examined the working mechanisms of acetic acid inhibition on dark fermentative hydrogen production. It was found that undissociated acetic acid (UAA) concentration was the critical factor in acetic acid inhibition. Hydrogen production activity decreased by 50 % and 90 % when UAA concentrations was 76.3 mg/L (1.27 mmol/L) and 686.7 mg/L (11 ...
