Abstract
Incubation of histidine-requiring auxotrophs of the bacterium Salmonella typhimurium with cyclohexane-, saline-, and serum-soluble surface components of respirable fly ash particles produced an increased number of revertants in two frameshift tester strains. The results are consistent with the hypothesis that both organic and inorganic mutagens are present in coal fly ash.
摘要
将鼠伤寒沙门氏菌的组氨酸营养缺陷型菌株与可吸入飞灰颗粒的环己烷可溶性、盐水可溶性和血清可溶性表面成分一起培养，在两种移码测试菌株中产生了数量增加的回复突变体。结果与煤飞灰中同时存在有机诱变剂和无机诱变剂的假设一致。
