Abstract
SummaryFruit vinegar can be obtained biologically from the fermentation of fruit wine using species of the genera Acetobacter. However, the productivity of vinegar is generally low because of the inhibition by substrate ethanol and product acetic acid. In this research, the yield of acetic acid, as well as the cell growth, in hawthorn vinegar fermentation was enhanced using beer for seed preparation. The higher yield of acetic acid of AC2005 was because of the higher alcohol dehydrogenase and aldehyde dehydrogenase activities caused by using beer for seed preparation. Furthermore, Acetobacter pasteurianus AC2005 showed acid stability during the fed‐batch fermentation of hawthorn vinegar.
