mutagenic effect of diethylamine in candida intermedia and C pelliculosa

ABSTRACT

The effect of diethylamine on C. intermedia survivals was severe at the concentration of 0. 5 ml/100 ml liquid minimal medium. Stimulation in survivals was obtained at the concentration of 0.7 ml DEA/100 ml LMM, while complete lethality was obtained at the concentration of 1 ml DEA. No mutants could be obtained, fore the species, by any of the different DEA concentrations used. The effect of DEA on C. pelliculosa survivals was gradual and mild until the concentration of 0.5 ml DEA/100 ml LMM and severe at the concentration of 0.7 ml DEA. Complete lethality was obtained at the concentration of 1 ml. No mutants were obtained from any of the different DEA concertrations used with C. pelliculosa, i.e., C. pelliculosa is similar to C. mutation by DEA in respect of mutation induction by DEA
