New enzyme for ethanol producers reduces use of chemicals and saves costs

The Danish biotech company Novozymes has announced the launch of 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.

Peter Halling, vice president for biofuels at Novozymes says that by using the new enzyme, ethanol producers can reduce dosing of both ammonia and sulphuric acid during the cook process, which saves costs and ensures a safer working environment.
