Abstract

Six species of microorganisms, Escherichia coli, Bacillus cereus, Lactobacillus acidophilus, Staphylococcus aureus, Streptococcus faecalis and Actinomyces niger, were grown under suitable conditions in appropriate media. Cadmium chloride was added to provide 0, 5, 10, 20, 40, and 80 mug of Cd per ml. At 40 and 80 mug of Cd per ml, E. coli and B. cereus grew well and the other species were repressed. Cd uptake patterns differed significantly among the species tested. The significance of these data with respect to Cd in food chains is discussed.

摘要

六种微生物,即大肠杆菌、蜡样芽孢杆菌、嗜酸乳杆菌、金黄色葡萄球菌、粪肠球菌和黑曲霉,在合适的条件下于适宜的培养基中培养。添加氯化镉,使每毫升培养基中镉的含量分别为0、5、10、20、40和80微克。当每毫升镉含量为40和80微克时,大肠杆菌和蜡样芽孢杆菌生长良好,而其他菌种受到抑制。受试菌种对镉的吸收模式差异显著。文中讨论了这些数据对于食物链中镉的意义。
