【摘要】 研究了单一稀土氯化亚铈(CeCl3)对谷氨酸棒杆菌的生长及谷氨酸脱氢酶(GDH)和乳酸脱氢酶(LDH)酶活的影响.结果表明:稀土元素在低剂量下能促进谷氨酸棒杆菌的生长;达到一定剂量会抑制菌体的生长;对酶活性的影响也是在低剂量下激活,在高剂量下抑制.更多还原

【Abstract】 In order to observe the biological effect of rare earth (RE) on Corynebacterium glutamicum S(9114), the effects of single compound CeCl(3) on the growth of Corynebacterium glutamicum S(9114) and the enzymatic activities of glutamate dehydrogenase ( GDH )and lactate dehydrogenase ( LDH ) were studied. The results showed that CeCl(3) accelerated the growth of Corynebacterium glutamicum S(9114) at low dosage range, but inhibited the growth when the dosage increased to certain content. The same effect was also observed for the enzymatic activities of GDH and LDH.更多还原
