ABSTRACT:
The Clostridium acetobutylicum mutant IFP 904 (ATCC 39058) is obtained by spreading a culture of a strain of Clostridium acetobutylicum at the surface of a solid culture medium containing n-butanol at a specified concentration, growing the strain in the presence of a mutagenic agent and recovering a strain of increased resistance to n-butanol. The resultant mutant can be used to produce a mixture of butanol and acetone of increased concentration.
