A reaction mechanism involving two dominating surface species, an inactive ethanol dimeric species adsorbed on Brønsted sites inhibiting ester formation and a co-adsorbed complex of acetic acid and ethanol on the active site reacting to produce ethyl acetate, is shown to describe the reaction rate...
especially in vinegar production, due to their ability to partially oxidize alcohols to acetic acid. However, economic bioproduction using AAB is challenged by harsh environments during acetic acid fermentation, among which initial ethanol pressure, subsequent acetic acid pressure, and consistently high te...

Ap CGMCC 1.41 and CICC 20001 produced the highest concentration of acetic acid at 6% ethanol, with initial concentrations of 0.5% and 1% acetic acid, respectively. However, the high initial acid concentration would also inhibit the fermentation process. The lengths of the lag phase in Ap CICC ...

Mechanism of Toxicity Acetic acid is present throughout nature as a normal metabolite of both plants and animals. Acetic acid may also be released to the environment in a variety of waste effuents, in emissions from combustion processes, and in exhaust from gasoline and diesel engines. If rele...
Carbon flux into the tricarboxylic acid (TCA) cycle correlated positively with cultivation temperature. These results indicate that the increased demand for energy (in the form of ATP), most likely caused by multiple stressors, including heat, acetic acid, and ethanol, was matched by both the ...
