Abstract

Prolonged adaptation of Ca-alginate immobilized cells of Pseudomonas acidovorans CA28 to a mixture of 3-chloroaniline (3-CA)1) and 2-CA and subsequently to 2-CA as sole substrate led to the isolation of another strain, termed CA50 with the additional capability of utilizing 2-CA as sole source of carbon, nitrogen, and energy. Batch-degradation of 190 mg/l of 2-CA at pH 6.1 by this newly isolated strain was achieved within 3 days, at higher concentrations up to 0.6 g/l increasing lag-phases and degradation periods were observed. Except chloride and ammonium no further metabolites were detectable in the medium. Mineralization of 2-CA proceeds via the modified ortho-cleavage pathway as demonstrated by the presence of catechol 1,2-dioxygenase (C120) activity, which is characterized by its substrate specificity and elution behaviour on DEAE-cellulose.
