Bacillus stearothermophilus에 의한 Xylanase 생산
Production of Xylanase by Bacillus stearothermophilus
초록
토양으로부터 세포외 xylanase를 다량 생산하는 균주를 분리하고 분리균의 형태적 내지는 생화학적인 특성을 조사하여 Bacillus stearothermophilus No.236로 동정하였다. 본 분리균은 초기 pH가 pH 6.5 인 0.75% xylan, 0.35% yeast extract, 1.06%
A bacterial strain capable of producing high level of extracellular xylanase was isolated from soil. The characteristics of the isolated strain No.236 were identified to be Bacillus stearothermophilus. The maximal xylanase production was observed in the medium containing 0.75% xylan, 0.35% yeast extract, 1.06%
