Mutagenesis of the obligate anaerobe Clostridium acetobutylicum was best accomplished using agents (e.g. ethyl methane sulphonate or N-methyl-N'-nitro-N-nitrosoguanidine) which are believed to act by a direct mutagenic mechanism. Other agents (e.g. u.v. radiation) whose effectiveness relies on misrepair of damaged DNA via an error-prone pathway, were poor mutagens of this organism. Procedures are described which readily yielded a variety of auxotrophic and other useful mutant strains of Cl. acetobutylicum and related saccharolytic clostridia.
