[Screening of Clostridium strains through ribosome engineering for improved butanol production].

Abstract excerpt

We used ribosome engineering technology, with which antibiotic-resistant strains are resulted from mutations on microbial ribosome, to screen a high butanol-producing Clostridium strain. A novel mutant strain S3 with high butanol production and tolerance was obtained from the original Clostridium acetobutylicum L7 with the presence of mutagen of streptomycin. Butanol of 12.48 g/L and ethanol of 1.70 g/L were...
