豆豉对小鼠吸收镉的影响及相关机制的初步探究

Effect of Douchi on the absorption of cadmium in mice and tentative study of related mechanisms

摘要: 为评价豆豉对小鼠吸收镉的影响,本文进行了豆豉在体外吸附重金属和动物实验。结果表明,从豆豉中分离得到6株细菌和2株真菌,这些微生物及其代谢产物可能导致豆豉在体外对镉的吸附率达到78.67%。豆豉组小鼠粪便中镉的含量显著低于对照组,这表明豆豉促进了小鼠对镉的吸收,从而增加了镉在肝脏中的积累。本研究为豆豉的合理食用提供科学的依据。

Abstract: To evaluate the effect of Douchi on the absorption of cadmium in mice,the adsorption of Douchi for heavy metal in vitro and animal experiments were carried out. The results showed that six strains of bacteria and two strains fungus were isolated from Douchi. Microbes and metabolites may cause Douchi to have good adsorption efficiency of 78.67% for cadmium in vitro. The content of cadmium in the feces of mice treated with Douchi was significantly lower than that in the control group. It indicated that Douchi promoted the absorption of cadmium in mice and aggravated the accumulation of cadmium in liver.It provided scientific basis for the reasonable edible of Douchi.
