Effects of temperature and hydrostatic pressure on bacteriolytic, autolytic and proteolytic activities were investigated at 10-40°C and at 1-1, 021 atm using a lytic enzyme-producing bacterium Bacillus sp. V 37 isolated from coastal regions of Japan. Lowering the temperature alone or in combination with increasing the hydrostatic pressure reduced the bacteriolytic, autolytic and proteolytic activities, but did not inhibit them completely. Significant levels of activity were still observed even at deep-sea pressures. The temperature characteristics of bacteriolytic activity calculated from the Arrhenius plot slightly decreased with increase in the hydrostatic pressure. Increased pressure had little effect on the autolytic activity, but it inhibited significantly both the lytic and proteolytic activities.
