Improving Acetic Acid Production by Over-Expressing PQQ-ADH in Acetobacter pasteurianus
Pyrroquinoline quinone-dependent alcohol dehydrogenase (PQQ-ADH) is a key enzyme in the ethanol oxidase respiratory chain of acetic acid bacteria (AAB). To investigate the effect of PQQ-ADH on acetic acid production by Acetobacter pasteurianus JST-S, subunits I (adhA) and II (adhB) of PQQ-ADH were over-expressed, the fermentation parameters and the metabolic flux analysis were compared in the e...
متن کاملAcetic acid fermentation of acetobacter pasteurianus: relationship between acetic acid resistance and pellicle polysaccharide formation.
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 stationary phases, but dispersed again in the secon...
متن کاملA novel high ethanol-thermo-tolerant Acetobacter pasteurianus KBMNS-IAUF-2 strain and the optimization of acetic acid production using the Taguchi statistical method
Because of the high energy consumption for fermentor cooling, the isolation of thermo-tolerant Acetobacter strains for vinegar production has a high priority. The aims of this study were the isolation and identification of a high ethanol-thermo-tolerant Acetobacter spp. from grapes as well as the optimization of conditions for increasing the acetic acid production. The grape e...

متن کاملRole of the glyoxylate pathway in acetic acid production by Acetobacter aceti.
Wild-type Acetobacter aceti NBRC 14818 possesses genes encoding isocitrate lyase (aceA) and malate synthase (glcB), which constitute the glyoxylate pathway. In contrast, several acetic acid bacteria that are utilized for vinegar production lack these genes. Here, an aceA-glcB knockout mutant of NBRC 14818 was constructed and used for investigating the role of the glyoxylate pathway in acetate p...
