Abstract
SOS Chromotest and Ames test were carried out to evaluate the mutagenicity of three chloropropanols. In the SOS Chromotest, 3-monochloro-l,2-propanediol (3-MCPD) and 2,3-dichloro-1-propanol (2,3-DCP) except for 1,3-dichloro-2-propanol (1,3-DCP) induced SOS response in Escherichia coli PQ37 with dose-response relationship and 2,3-DCP was far more genotoxic than 3-MCPD. The genotoxic activities of both compounds, however, were very lower in E. coli PQ35 (PQ37
3-Chloro-1,2-propanediol (3-MCPD), 1,3-dichloro-2-propanol (1,3-DCP), 2,3-dichloro-1-propanol (2,3-DCP)과 같은 chloropropanol들이 일부 식품에서 검출됨으로서 위해성 논란이 제기되었기에 본 연구에서는 Ames test와 SOS Chromotest를 이용하여 미생물 시험계에서의 chloropropanol류의 유전독성 및 변이원성을 검토하였다. E. coli PQ37에서는 1,3-DCP를 제외한 3-MCPD와 2,3-DCP는 뚜렷한 용량반응 관계를 보이며 SOS반응 유도활성을 나타내어 유전독성이 있는 것으로 판단되었고 3-MCPD보다는 2,3-DCP가 강한 유도활성을 나타내었다. 또한 E. coli PQ35 (PQ37
