Clostridium beijerinckii BA101 mutant fermentation time course. Clostridium beijerinckii BA101 mutant fermentation time course

The fermentation culture of Clostridium beijerinckii mutant BA101 was monitored from exponential growth to stationary phase. During this period the culture underwent a shift from acidogenesis to solventogenesis. Acetone and butanol production was initiated with the onset of the solventogenic phase. Using DNA microarray changes in gene expression were examined during the transitional period. Overall design: RNA samples were taken from Clostridium beijerinckii mutant BA101 fermentation culture at individual time points during the acidogenic phase and the solventogenic phase. The samples were used for microarray hybridization.
