【摘要】 研究不同浓度(2、4、6、8、10 mg/m L)乳铁蛋白对大肠杆菌生长促进或抑制的情况。结果表明,浓度≥6 mg/m L时,乳铁蛋白在初期发挥抑菌作用,其后表现出良好的营养促进剂的作用,大肠杆菌的生长比对照组更加旺盛;浓度≤4 mg/m L时,乳铁蛋白并不抑制大肠杆菌的生长,表现出明显的营养作用。更多还原

【Abstract】 In this experiment, the proliferation or inhibition effect of Lf on the growth of Escherichia coli under different conditions(2, 4, 6, 8, 10 mg/m L) were discussed. The results showed that when concentration was ≥6mg/m L, Lf played bacteriostasis function during the early stage of incubation and then had a significant effect on multiplication of E. coli as a nutritional enhancer; when concentration was ≤4 mg/m L, Lf show not incubation,but nutrition.更多还原
