The Gram-negative,bacterium TX-12 with high CMCase-producing activity has been screened and isolated from decaying plants of the sea.The strain is identified to be a kind of Cellulophaga sp.The results of CMCase producing research show that the optimal pH value is 8.0,and the optimal temperature is 25 ℃.Under this condition,the highest CMCase activity reached to 354.8 U/mL after shaking flask culture for 56 h.The primary study on enzymatic properties show that the optimal temperature and pH for the enzymati...
