The invention relates to the microbial synthesis of polyhydroxyalkanoic acids &lsqb;PHA(B)&rsqb; from substrates which have potential environmental toxicity and must therefore be detoxified and which, if capable of being utilized as a source of carbon and energy by microorganisms for growth and propagation, exhibit the phenomenon of substrate inhibition. According to the invention, a process for the continuous microbiological production of PHB is provided, which process is characterized in that strains of microorganisms known to be PHB producers are propagated chemo-statically at maximum heat production on substrates exhibiting growth inhibition in case of excess substrate, the maximum heat production corresponding to a maximum PHB content in the biomass being adjusted by means of the substrate flow rate.

Method for the continuous microbiological production of polyhydroxy butyric acid

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.
