牛血Cu/Zn-SOD的热稳定性      SOD  稳定性  热变性  SOD活性  比活力       2007/8/5
摘要:研究了不同的Cu2+和Zn2+浓度配比对SOD热稳定性的影响,并测定了SOD活性及利用考马斯亮蓝G-250法测定蛋白质含量.结果表明在Cu2+、Zn2+分别为5.4mmol/L和3.6 mmol/L时SOD的活性最高,达到了92.6%;在75℃时大部分杂蛋白变性沉淀,SOD的比活力最高.最后确定在加入5.4 mmol/L Cu2+,3.6 mmol/L Zn2+条件下, 75℃下热变性,可以...
Copper-bearing montmorillonite (Cu-MMT) was produced by Cu2+ cation exchange reaction. X-ray diffraction analysis showed that that the (001) basal spacing of the MMT crystal lattice increased from 1.5...
Two hundred forty 1-d-old Arbor Acres broiler chicks were used to investigate the effects of Cu (II)-exchanged montmorillonite (CEM) or montmorillonite on the growth performance, intestinal microflora...
In vivo antagonistic effect of Lactobacillus helveticus CU 631 and Lactobacillus spp. against typical enteritis causing pathogen Salmonella enteritidis KU 101 have been determined, which showed an inc...
Tilapia zilli were exposed to the same concentration (1 mg/L) of essential (Cu, Zn) and non-essential (Cd, Pb) metals for 10 days so that these metals would accumulate in the liver, gill, brain and mu...
