AB  - Laboratory studies using chemical concentrations comparable to those found in 
      nature have provided considerable knowledge of microbial transformations in 
      nature. Although the number of studies performed is increasing rapidly, the 
      effects of low substrate levels on growth, enzyme induction, enzyme activity, and 
      the use of mixtures of substrates have not yet been clarified. Likewise, studies 
      at low concentrations in seawater are lacking. This paper describes a study of 
      the rates of degradation of chlorophenols 4-chlor-2-methylphenol, 
      2,4-dichlorophenol (2,4-DCP), and 2,4,6-trichlorophenol at concentrations ranging 
      from 2 to 18 micrograms/liter. The compounds were tested separately, in a 
      mixture, and in waste water containing other organics. The obtained rates of 
      2,4-DCP in seawater were comparable to those found in fresh water. Also, the 
      rates were in general agreement with a kinetic model proposed for degradation of 
      chlorophenols. The rates of degradation of chlorophenols in the mixture were 
      comparable to those found when tested separately. In the waste, very low rates 
      were observed. It is suggested that this might be explained by a toxic effect, 
      caused by other substances in the waste water, on the microorganisms considered 
      to be active in degrading the chlorophenols at low concentrations.
