Open the CIPO recordAbstract From the Canadian patent
This invention provides novel mutant strains of microorganisms (e.g. Pseudomonas putida Biotype A) which are capable of converting substrates such as toluene p-xylene, catechol and 4-methylcatechol to 2-hydroxymuconic semialdehyde or substituted analog of 2-hydroxymuconic semialdehyde quantitatively by the meta (catechol 2,3-oxygenase) pathway. No active 2-hydroxymuconic semialdehyde-metabolizing enzymes are induced in the microorganism thereby permitting, a 2-hydroxymuconic semialdehyde type metabolite to be produced and accumulated in a bioconversion medium containing the microorganism.
