V. parahaemolyticus possessed an extracellular alkaline protease activity during the stationary growth phase. Various factors such as initial pH of medium, incubation temperature and shaking rate were investigated for optimizing the production of allcaline protease from V. parahaemolyticus ATCC 17802. Maximal activity of the protease was obtained when the bacteria were grown in 2% skim milk medium in 0.1 M tris/HCl buffer (pH 7.6). Maximal activity of the protease was obtained when the bacteria were grown at initial pH of 7.6, incubation temperature of 37℃ and shaking rate of 250 rpm.
