To produce functional and high nutritional chungkook-jang, an immuno-stimulating and rapid growing bacterium was isolated from one of Korean traditional food, chungkook-jang. The isolated bacterium was identified as Bacilpumilus and deposited in Korean Collection for Type Culture (KCTC 10461BP). The chungkook-jang fermented by JB-l has good taste and pleasant smell with high content of free amino acids, and the water extract of chungkook-jang showed 410% of immuno-stimulation activity at concentration of 2 mg/ml. The rapid fermentation in 16 h is achieved by inoculation of 20 ml culture broth of JB-l into 6 kg cooked soybean in commercial scale at
