From: Direct conversion of cellulose to l-lactic acid by a novel thermophilic Caldicellulosiruptor strain
Lactic acid, acetic acid and ethanol production by Caldicellulosiruptor DIB 104C wild-type strain and evolved strain clone 45. Wild-type strain (A, B) and evolved clone 45 (C, D) were grown in fermenters on microcrystalline cellulose at 70 °C with pH stabilized at 6.4. Lactic acid, acetic acid and ethanol concentrations (g/l) (A, C) and products ratio (wt%) (B, D) in formed fermentation products (lactate + acetate + ethanol) are presented
