Novozymes has launched Spirizyme® 2.0 T and Spirizyme Ultra T glucoamylase enzymes with trehalase for the European ethanol market. The products, which are part of the Spirizyme T Portfolio to deliver increased yield and sugar conversion, were introduced earlier this year for the U.S. market.
Trehalose, a type of sugar that is normally left unfermented in a standard ethanol plant, is targeted by the trehalase enzyme to produce glucose, which is then fermented to ethanol. Trehalose makes up a significant part of the ‘DP2 peak’, which is a measure of disaccharides and contributes to the overall residual sugar in an ethanol plant. The more DP2 an ethanol plant can convert, the more ethanol it will produce.
