Isolation and partial characterization of a non-motile mutant ofClostridium acetobutylicum

Summary A non-motile mutant ofClostridium acetobutylicum, morphologically indistinguishable from the motile parent, was capable of solvent production, suggesting that motility is not a regulatory trigger for solventogenesis. However, solventogenesis was considerably weaker than that of the parent, providing evidence of a positive relationship between solvent production and motility.
