Vanillin catabolism in Rhodococcus jostii RHA1

Hao-Ping Chen et al. Appl Environ Microbiol. 2012 Jan.

Abstract

Genes encoding vanillin dehydrogenase (vdh) and vanillate O-demethylase (vanAB) were identified in Rhodococcus jostii RHA1 using gene disruption and enzyme activities. During growth on vanillin or vanillate, vanA was highly upregulated while vdh was not. This study contributes to our understanding of lignin degradation by RHA1 and other actinomycetes.
