Time course of a cell growth and total amount of active cells (CDW multiplied by reciprocal value of inactive cells from chart c), b metabolite formation c pH and percentage of inactive cells, d distribution of different sub-populations according to their LS and fluorescence staining patterns for the sporulating phenotype and ABE fermentation carried out on TYA medium with external addition of 5 g/L butanol prior to fermentation. Error bars represent standard deviations of three independent biological replicates, and calculated values are presented without error bars
