FIG 3.

Batch fermentation profiles of the C. saccharoperbutylacetonicum mutants compared to the wild type in MP2 medium. (A) Cell growth; (B) glucose consumption; (C) pH profiles; (D) acetate production; (E) butyrate production; (F) lactate production; (G) acetone production; (H) ethanol production; (I) butanol production. N1-4, C. saccharoperbutylacetonicum N1-4; deltpta, C. saccharoperbutylacetonicum deltpta; deltbuk, C. saccharoperbutylacetonicum deltbuk; deltptabuk, C. saccharoperbutylacetonicum deltptabuk. Fermentation was carried out in replicates, and results from one batch are reported here as representative.
