Five textile azo dyes viz. C. I. acid violet 17, C. I. acid green 16,
C. I. acid red 85, C. I. acid red 114 and C. I. direct green 6, were t
ested for bacterial mutagenicity with Salmonella typhimurium TA98 and
TA100 strains using a plate incorporation assay. After testing over a
concentration range of 1 mug to 500 mug with and without metabolic act
ivation these dyes showed no mutagenicity or toxicity.
