【摘要】 本文用Ames鼠伤寒沙门氏菌微粒体系检测北京风化煤总腐植酸和黄腐植酸的诱变性。检测的菌株用的是TA98和TA100,并从大白鼠的肝脏制取S-9体系。我们用点样法和平板法检测这二种腐植酸均得到阴性反应,由此可知这二种腐植酸不是诱变剂。但是,它们在TA100菌平板上诱发回变菌落数略高于对照组,差异有非常显著性意义,故我们认为它们也存在着诱变的可能性,此问题有待以后深入研究。更多还原

【Abstract】 Beijing Humic Acid and Fulvic Acid were tested for mutagenicity with the Ames Salmonella/microsome system. The strains for testing were TA98 and TA100. The mic-rosomes were isolated from rat livers. The revertant colonies obtained from both spot test and plate test were obviously higher than the control, but still less than two times the control. By definition, we can not say that HA and FA are mutagenic material.更多还原
