The invention discloses an efficient protease producing bacterium and protease producing conditions. The efficient protease producing bacterium is separated from a seabed surface sediment of the Bohai Sea, is classified and named as bacillus BH70049 (Bacillusaltitudinis) and is already preserved at the Center for General Microbiology of China Committee for Culture Collection of Microorganisms (hereinafter referred to as CCCCM, and the address is No.3 yard, beichen west road No.1, chaoyang district, Beijing), and the preservation number is CGMCC No.12490. The strain is high in growth speed, strong in protease producing capability and high in enzyme activity and capable of degrading casein, gelatin and elastin, is applied to sewage treatment, decomposes suspended particles in ocean, promotes degradation of marine organic nitrogen and maintains the nitrogen cycle balance of a marine ecosystem. Wide important sources of industrial protease preparations are provided, and the efficient protease producing bacterium has the good application prospect in the industries of foods, medicines, leather making, detergents, cosmetics, textiles, animal and plant proteins, waste treatment and the like.
