BACTERIUM SPECIES COMAMONAS ACIDOVORANS P4a AND PROCESS FOR THE MICROBIAL DECONTAMINATION OF MATERIALS POLLUTED WITH PHENOXYACETIC ACID HERBICIDES

摘要

The invention relates to a novel bacterium species comamonas acidovorans P4a (DSM 10574) and a process for the microbial decontamination of materials, water or soils contaminated by herbicides, especially 2,4-dichloro and/or 4-chloro-2-methylphenoxy acetic acid (2,4-D and/or MCPA) or their salts. The bacterial species of the invention is stable and metabolically active up to pH values of 12.5 and tolerates heavy pollution with the toxic compounds 2,4-D and MCPA.
