6种微生物，大肠杆菌，蜡样芽孢杆菌，嗜酸乳杆菌，金黄色葡萄球菌，粪链球菌和尼日尔放线菌，生长在适当的培养基中的适当条件下。加入氯化镉以提供0、5、10、20、40和80 μ g Cd/ml。在40和80 μ g/ml镉浓度下，E. coli和B. cereus生长良好，其他物种受到抑制。镉吸收模式之间存在显着差异的物种测试。这些数据与镉在食物链中的意义进行了讨论。
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.
