From: Production of 1,3-PDO and butanol by a mutant strain of Clostridium pasteurianum with increased tolerance towards crude glycerol

  Technical grade glycerol(Jensen et al.[2012]) Stored crude glycerol + activated stone carbon (Jensen et al.[2012]) Stored crude glycerol + activated stone carbon
Wild type Wild type MNO6

Maximum 1,3-PDO rate 0.64 g/l/h 0.91 g/l/h 1.21 g/l/h
Maximum Butanol rate 1.21 g/l/h* 1.30 g/l/h 1.80 g/l/h
