Elucidation of the 4-hydroxyacetophenone catabolic pathway in Pseudomonas fluorescens ACB [PDF]

, 2008
The catabolism of 4-hydroxyacetophenone in Pseudomonas fluorescens ACB is known to proceed through the intermediate formation of hydroquinone. Here we provide evidence that hydroquinone is further degraded through 4-hydroxymuconic semialdehyde and ...
