Abstract

Two genes, aldA, and mnoA, encoding an NAD-dependent aliphatic dehydrogenase and N,N'-dimethyl-4-nitrosoaniline-dependent methanol dehydrogenase, respectively, are strongly expressed when Rhodococcus erythropolis N9T-4 is grown under oligotrophic conditions. In this study, we found a transcriptional regulator required for the transcription of both aldA and mnoA. The transcriptional regulator was also found to be essential for the oligotrophic growth of N9T-4.

Keywords: Rhodococcus erythropolis; aldehyde dehydrogenase; methanol dehydrogenase; oligotrophy; transcriptional regulator.
