A. aceti WK, a strain producing acetic
acid, was screened and adapted for vinegar
production using corn wine as a substrate. The
complex medium used for vinegar production
consisted of (per 1 L of water): glucose, 5.0 g;
yeast extract, 2.5 g; and peptone, 1.0 g. The total
acidity concentration of the vinegar and alcohol
was controlled, with the concentration at start-up
being 7% that consisted of 3.5%(v/v) vinegar and
