All seven oral Actinomycetaceae tested grew in broth containing 10 microgram/ml Cd. After 24 hours' growth A viscosus WVU 626 bound nearly 20 microgram Cd/mg dry wt. The amount of Cd bound varied during the growth cycle, being maximal (90 to 100 microgram/mg dry wt.) after 5 hours' growth. Addition of 50 microgram/ml chloramphenicol to actively growing cells inhibited further Cd binding. In contrast S mutans FA1 was greatly inhibited by 2.5 microgram/ml Cd and bound only 1.3 microgram Cd/mg after 24 hours' growth in broth containing 2.5 microgram/ml Cd.
所测试的全部七种口腔放线菌科细菌都能在含有10微克/毫升镉的肉汤中生长。生长24小时后，粘性放线菌WVU 626结合了近20微克镉/毫克干重。在生长周期中，镉的结合量有所变化，生长5小时后达到最大值（90至100微克/毫克干重）。向活跃生长的细胞中添加50微克/毫升氯霉素会抑制镉的进一步结合。相比之下，变形链球菌FA1在含有2.5微克/毫升镉的肉汤中生长24小时后，受到2.5微克/毫升镉的强烈抑制，仅结合1.3微克镉/毫克。
