title: Mutagenicity of glycerol chlorohydrines and of their esters with higher fatty acids present in protein hydrolysates.
abstract: 3-chloro-1,2-propanediol and 1,3-dichloro-2-propanol caused base substitutions in Salmonella typhimurium TA1535 both with and without metabolic activation. Metabolic activation seemed to act mainly by decreasing the toxicity of these compounds. A difference in the growth of the wild-type and repair-deficient strains of Escherichia coli was observed only for 1,3-dichloro-2-propanol with S9 mix. Esters of both chlorohydrines with fatty acids has smaller mutagenic effects than unesterified compounds.
