The analysis of enzymes associated with metabolism of phenolics by Stenotrophomonas maltophilia LK-24 was conducted. To identify metabolites of phenol and phenol compound, we investigated enzymes of S. maltophilia LK-24 associated with degradation of phenolics. We found that phenol hydrolase, catechol-2.3-dioxygenase, 2-hydroxymuconic semialdehyde dehydrogenase, 2-hydroxymuconic semialdehyde hydroxylase and acetaldehyde dehydrogenase were activated. The results showed that phenolics were gone through the meta-pathway ring cleavage. The results will contribute greatly to understand metabolic pathways of phenol and it is possible to make some assessment of the feasibility of using S. maltophilia LK-24 for the treatments of phenolic-contaminated waste streams.
