Isolation of Agar Degrading Bacteria, Cytophaga sp. ACLJ-18 and Optimization of Enzyme Production
한천 분해균 Cytophage sp. ACLJ-18의 분리 및 효소 생산 조건 최적화
Abstract
The strain which produces agar degrading enzyme was isolated from chiton(Liolophura japonica). The strain was identified as Cytophaga sp. through its morphological, physiological, and biological characteristics. For the production of agar degrading enzyme, 0.3% nutrient broth, 0.2% yeast extract and 0.5% agar was used as nitrogen and carbon source, respectively. The optimal initial pH, NaCl and temperature for the agar degrading activity of Cytophaga sp. were 7.0, 2.0% and
군부에서 분리한 한천 분해 균주의 최적 효소 생산 조건은 질소원으로 nutrient broth, yeast extract를 각각 0.3%, 0.2%였고, 탄소원으로는 agar 0.5%가 가장 적절한 조건이었다. NaCI 농도는 2.0 % %, pH 7.0, 온도는
