A Review of Process-Design Challenges for Industrial Fermentation of Butanol from Crude Glycerol by Non-Biphasic Clostridium pasteurianum
Butanol, produced via traditional acetone-butanol-ethanol (ABE) fermentation, suffers from low yield and productivity. In this article, a non-ABE butanol production process is reviewed. Clostridium pasteurianum has a non-biphasic metabolism, alternatively producing 1,3-propanediol (PDO)-butanol-ethanol, referred to as PBE fermentation. This review discusses the advantages of PBE fermentation wi...
متن کاملBUTANOL PRODUCTION FROM GLYCEROL BY Clostridium pasteurianum IN DEFINED CULTURE MEDIA- A PHENOTYPIC APPROACH
Title of Document: BUTANOL PRODUCTION FROM GLYCEROL BY Clostridium pasteurianum IN DEFINED CULTURE MEDIAA PHENOTYPIC APPROACH. David Leonardo Ramos Sanchez, Master of Science, 2009 Directed By: Associate Professor Nam Sun Wang Department of Chemical and Biomolecular Engineering ABSTRACT The fluctuations in oil prices have stimulated the production of renewable biofuels, in particular the produc...
متن کاملChanges in Membrane Plasmalogens of Clostridium pasteurianum during Butanol Fermentation as Determined by Lipidomic Analysis
Changes in membrane lipid composition of Clostridium pasteurianum NRRL B-598 were studied during butanol fermentation by lipidomic analysis, performed by high resolution electrospray ionization tandem mass spectrometry. The highest content of plasmalogen phospholipids correlated with the highest butanol productivity, which indicated a probable role of these compounds in the complex responses of...
متن کاملBio-butanol production from glycerol with Clostridium pasteurianum CH4: the effects of butyrate addition and in situ butanol removal via membrane distillation
BACKGROUND Clostridium pasteurianum CH4 was used to produce butanol from glycerol. The performance of butanol fermentation was improved by adding butyrate as the precursor to trigger the metabolic pathway toward butanol production, and by combining this with in situ butanol removal via vacuum membrane distillation (VMD) to avoid the product inhibition arising from a high butanol concentration. ...
متن کاملWhole-genome sequence of an evolved Clostridium pasteurianum strain reveals Spo0A deficiency responsible for increased butanol production and superior growth
BACKGROUND Biodiesel production results in crude glycerol waste from the transesterification of fatty acids (10 % w/w). The solventogenic Clostridium pasteurianum, an anaerobic Firmicute, can produce butanol from glycerol as the sole carbon source. Coupling butanol fermentation with biodiesel production can improve the overall economic viability of biofuels. However, crude glycerol contains gro...
