Autolytic Activity and Butanol Tolerance of Clostridium acetobutylicum

ABSTRACT

The effects of acetone and butanol on the growth of vegetative cells and the stability of swollen-phase bright-stationary-phase cells (clostridial forms) of Clostridium acetobutylicum P262 and an autolytic deficient mutant (lyt-1) were investigated. There was little difference in the sensitivity of strain P262 and the lyt-1 mutant vegetative cells and clostridial forms to acetone. The stability of the different morphological stages was unaffected by acetone concentrations far in excess of those encountered in factory fermentations. Butanol concentrations between 7 and 16 g/liter, which are within the range obtained in industrial fermentations, increased the degeneration of strain P262 clostridial forms but had no effect on the stability of lyt-1 clostridial forms which never underwent autolysis. Vegetative cells of the lyt-1 mutant were able to grow in higher concentrations of butanol than strain P262 vegetative cells. It was concluded that there is a relationship between butanol tolerance and autolytic activity.
