NOVEL BACILLUS AMYLOLIQUEFACIENS BY04 HAVING HIGH PROTEASE PRODUCING ACTIVITY AND PROCESS FOR PRODUCING PROTEASE USING THE SAME

摘要

PURPOSE: Novel Bacillus amyloliquefaciens by04 with improved protease productivity is provided to produce protease in a proper culture medium at a proper culture temperature for a predetermined time. CONSTITUTION: Bacillus amyloliquefaciens BY04(deposit: KCTC18219P) has improved protease productivity. The strain is isolated from doenjang(fermented soybean paste) or cheonggukjang(fermented soybeans). A method for producing protease comprises: a step of culturing the Bacillus amyloliquefaciens BY04 strain at 23-44 deg. C for 24-48 hours; and a step of collecting protease from the culture medium.
