Transcription profiling of P. putida KT2440 cultivated at 7 bar and at 7 bar with elevated dissolved oxygen tension

ABSTRACT: We investigated the changes of gene expression in PHA-producing Pseudomonas putida KT2440 cultivated under elevated pressure (7 bar) and under combined elevated pressure (7 bar) and elevated dissolved oxygen tension by means of DNA microarrays. RNA samples were isolated from cells cultivated in chemostat under very well defined growth conditions (growth rate, medium, temperature, pH,...)

BACKGROUND: Elevated pressure, elevated oxygen tension (DOT) and elevated carbon dioxide tension (DCT) are readily encountered at the bottom of large industrial bioreactors and during bioprocesses where pressure is applied for enhancing the oxygen transfer. Yet information about their effect on bacteria and on the gene expression thereof is scarce. To shed light on the cellular functions affected by these specific environmental conditions, the transcriptome of Pseudomonas putida KT2440, a bacter  ...[more]
