Abstract
The invention relates to the new bacterial strain Corynebacterium sp. K2-17 and to a process for the microbial decontamination of materials polluted with compounds from the production of phenoxyalkanoic acid herbicides, such as 2,4-dichlorophenoxybutyric acid (DCPB), 4-chloro-2-methylphenoxybutyric acid (MCPB), 2,4-dichlorophenoxyacetic acid (2,4-D), 4-chloro-2-methylphenoxyacetic acid (MCPA), 2,4-dichlorophenol (DCP), and 4-chloro-2-methylphenol (MCP) in a pH range of from slightly acidic to strongly alkaline.

A biologically pure Aureobacterium sp. strain DSMZ 11288.
A process for the microbial decontamination of materials polluted with compounds from the production of phenoxyalkanoic acid herbicides, comprising the step of contacting the polluted materials with the biologically pure Aureobacterium sp. strain DSMZ 11288 in a range of from slightly acidic to alkaline at pH values between 6 and 12.5 under aerobic conditions at temperatures between 10 and 38° C.
