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.
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.
