Enzyme for Ethanol Producers Reduces Chemicals, Saves Costs

Novozymes has launched a new enzyme for ethanol producers who want to reduce their use of chemicals without sacrificing yield.

Liquozyme LpH is an alpha-amylase effective at low pH that thins the mash by breaking down starch into shorter dextrin chains. A more fluid mash ensures more efficient operational performance for ethanol producers running their production at low pH.

Plant trials have shown improved viscosity levels and liquefaction, enabling customers to reduce their use of chemicals for pH adjustment, Novozymes says.

Peter Halling, vice president for biofuels at Novozymes, says the trials show “ethanol producers can reduce dosing of both ammonia and sulphuric acid during the cook process. This saves costs and ensures a safer working environment.”

Halling says the company will further expand its range of enzyme products for the ethanol industry by the end of the year.
