What is DP2?

Ethanol is produced by the fermentation of sugar by yeast. Commercial production of fuel ethanol involves breakdown of starch in corn or other feedstocks into simple sugars, fermentation of these sugars by yeast, and finally recovery of the ethanol and byproducts (e.g. animal feed).

Unfermented sugars go to waste, and ethanol producers are therefore interested in technologies that increase efficiency. After fermentation, ethanol plant managers will run High-Performance Liquid Chromatography (HPLC) tests to measure the amount of residual sugar. The test measures four types of sugars: DP1 (single sugar chains such as glucose), DP2 (two-sugar chains such as trehalose), DP3 (3-sugar chains) and DP4 (everything else).

Reducing these sugar “peaks” is key to maximize ethanol production. At a typical ethanol plant, approx. 70 percent of DP2 is unfermentable trehalose, so by converting trehalose to a fermentable sugar you can increase yield considerably. That is what the enzyme trehalase does.
