Transcription profiling by array of acidogenic chemostat cells of Clostridium acetobutylicum in response to n-butanol


ABSTRACT: Clostridium acetobutylicum is well-known for its butanol production. Butanol toxicity is a major drawback for the generation of high-butanol producing strains. Here, the transcriptional response a steady state, acidogenic (pH 6), phosphate-limited Clostridium acetobutylicum chemostat culture to different levels of n-butanol (0.25-1%) was investigated. For the butanol challenge experiments butanol (1-butanol) was added (a) to the supplying medium and (b) to the culture vessel to guarantee an immediate change in the butanol concentration. Addition of butanol to the culture was timed to match the supply of the new medium through the feedlines. The butanol concentration was increased stepwise in intervals of 66.6 h (5 volume changes) to moderate butanol concentrations of 0.25%, 0.5%, 0.75% and 1% (v/v).
