【摘要】 目的:研究乳酸菌对无机硒的吸收利用程度,以寻找对无机硒有机转化的生物载体。方法:采用紫外分光光度法,对加入不同量无机硒乳酸菌进行培养处理后测定其硒含量,计算对其吸收利用率。结果:乳酸菌的吸收利用率最高者为98.5%、最低者为72.7%,结论:乳酸菌对无机硒吸收程度较高,有一定研究和应用价值。更多还原

【Abstract】 Objective: To study the degree of lactobacillus absorbing and using selenium,in order to find the biology carrier to transform inorganic selenium into organic selenium.Methods: We cultured the lactobacillus,by adding the different amount of inorganic selenium,and measured the selenium content in the culture productions by ultraviolet spectroscopy to calculate the inorganic selenium absorbing-using ratio.Results: In the select lactobacillus,the highest absorbing-using ratio was 98.5% and the lowest was 72.7%.Conclusion: the select lactobacillus made greater inorganic selenium absorbing-using ratios,and deserve to be further study and use.更多还原
