Welcome to Terranol 

Terranol A/S develops yeasts to be applied in 2. generation bioethanol production.

First generation bioethanol is produced from agricultural feedstock, such as sugar cane, sugar beet, and corn, whereas 2. generation bioethanol is produced from agricultural wastes, such as wheat straw, sugar cane bagasse, corn stover and wood chips.

The manufacturing process for bioethanol involves pretreatment of biomass, enzymatic hydrolysis, fermentation, and distillation. Biomass contains the so-called C6 sugars, primarily from cellulose, and C5 sugars from the hemicellulose part of the plant material. After enzymatic hydrolysis yeasts ferment C6 sugars to ethanol whereas C5 sugars are not fermented to ethanol by any natural microorganism in sufficiently high concentrations.

Yeast is a traditional ethanol producing microorganism. By applying proprietary technologies, Terranol has developed industrial yeasts that can efficiently convert all C6 sugars and also the C5 sugar xylose in biomass into ethanol, at a rate that is among the best obtained today. The development work is performed in consideration of the thermochemical treatment of biomass and enzymatic hydrolysis. Therefore, Terranol has engaged with leading players in these fields.

A yeast strain capable of efficient conversion of the various sugars in residual biomass from agriculture facilitates further modification of the strain for production of other compounds, that can substitute for oil based chemicals used in the industry today.
