Fuel ethanol production from L-arabinose: Constraints, challenges, current status and future trends
- National Center for Agricultural Utilization Research, Peoria, IL (United States)
Interest in fermentation of L-arabinose to ethanol has increased in recent years because corn fiber contains 11% L-arabinose and is available in sufficient quantities to serve as a low cost feedstock to produce fuel ethanol. Various L-arabinose utilizing yeasts were screened for cost feedstock to produce fuel ethanol of their ability to ferment L-arabinose to ethanol. Most yeasts produced L-arabitol instead ethanol. The optimal conditions for production of L-arabitol in high yield from L-arabinose alone, in mixed sugars and in corn fiber acid hydrolyzate by certain yeasts will be described. In addition, the fermentative performance of an ethanologenic recombinant organism on L-arabinose will be discussed. Current status of microbial fermentation of L-arabinose to ethanol, problems and prospects of ethanol production from L-arabinose by yeasts and future directions of research will be reviewed.
