TI  - Influence of environmental factors on 2,4-dichlorophenoxyacetic acid degradation 
      by Pseudomonas cepacia isolated from peat.
PG  - 317-22
AB  - A Pseudomonas cepacia, designated strain BRI6001, was isolated from peat by 
      enrichment culture using 2,4-dichlorophenoxyacetic acid (2,4-D) as the sole 
      carbon source. BRI6001 grew at up to 13 mM 2,4-D, and degraded 1 mM 2,4-D at an 
      average starting population density as low as 1.5 cells/ml. Degradation was 
      optimal at acidic pH, but could also be inhibited at low pH, associated with 
      chloride release from the substrate, and the limited buffering capacity of the 
      growth medium. The only metabolite detected during growth on 2,4-D was 
      2,4-dichlorophenol (2,4-DCP), and degradation of the aromatic nucleus was by 
      intradiol cleavage. Growth lag times prior to the on-set of degradation, and the 
      total time required for degradation, were linearly related to the starting 
      population density and the initial 2,4-D concentration. BRI6001, grown on 2,4-D, 
      oxidized a variety of structurally similar chlorinated aromatic compounds 
      accompanied by stoichiometric chloride release.
