Yeast & Protein Platform

Once biomass is fractionated into cellulose, xylose and lignin fractions utilizing the PureVision technology, what remains is black liquor. While in the past, cleanup of the black liquor has been a major problem and cost for the pulp & paper industry, PureVision is able to utilize its black liquor. Working with a synergistic biomass utilization technology, this black liquor becomes a biogrowth medium to grow non-genetically modified yeast at the biorefinery to be used for fermenting sugars into alcohol. The remainder of the yeast as well as the mature yeast from fermentation can be recovered and processed into high-protein animal food. The animal feed markets are well established and are virtually unlimited – especially with the collapse of wild fish stocks and the growing worldwide human appetite for higher quality protein.
