Transcriptome analysis of G. oxydans 621H in response to L-arabinose

DNA microarray analysis was performed to check whether the addition and/or oxidation of L-arabinose to the growth medium of G.oxydans 621H possibly affects short-term global gene expression. Addition of 1% (w/v) L-arabinose supplemented in the mid-exponential growth phase to G. oxydans 621H cells cultured in 4% (w/v) mannitol medium were compared to the respective control culture where water was added instead of L-arabinose.
