【摘要】 从近江牡蛎(Jinjiang Ostrea vivularisGould)肠道中分离出21株菌,其中9株革兰氏阳性菌,12株革兰氏阴性菌。并检测其蛋白酶、脂肪酶、淀粉酶、纤维素酶的产酶能力。结果表明,13株菌(61.9%)能分泌蛋白酶,13株(61.9%)分泌淀粉酶;11株(52.4%)产脂肪酶;7株(33.3%)产纤维素酶。产4种酶的有5株,产3种酶的3株,产2种酶的5株,产1种酶的3株,不产酶的仅有5株。产酶菌株的比例高达76.2%(16/21),可见近江牡蛎肠道细菌对食饵消化有重要作用。更多还原

【Abstract】 21 strains bacteria were isolated from Jinjiang Ostrea vivularis Gould(JOV),among them 9 were Gram positive,and 12 were Gram negative.Their zymogenicities of protease,lipase,amylase,and cellulase were measured.The results showed that 13 strains(61.9%) were able to produce extra-cellular protease and amylase,11 strains(52.4 %) excrete lipase,7 strains(33.3%) cellulase.Among them 5 strains excrete four kinds of enzyme,3 strains three kinds of enzyme,5 strains two kinds of enzyme,and 3 strains one enzyme.And only 5 strains produce no enzyme.The rate of enzyme-producing strain is as high as 76.2%(16/21).Therefore,it is clear that bacteria in intestine of JOV play an important role in the digestion of food.更多还原
