SPORL Patent: Ethanol Produced as By-product, or from Waste, or from Cellulosic Material Substrate, or Substrate that Contains Cellulosic Material

The present invention relates to a method using sulfite pretreatment to overcome recalcitrance of lignocellulose (SPORL). More specifically, it relates to a sulfite-based chemical process for pretreating biomass in solutions to reduce access barriers of enzymes to the lignocellulose, resulting in efficient conversion through enzymatic saccharification.
