C5+C6 mixed sugar fermentation

​C5+C6 mixed sugar fermentation ferments both C5 and C6 sugars for 40-45% higher ethanol yield than C6 fermentation. C5+C6 mixed sugar fermentation is ready for licensing and this concept is operational at our demonstration plant in Kalundborg

 

 

Higher Ethanol yieldHigher Ethanol yield

​By fermenting both C6 and C5 sugars, you can expect cellulosic ethanol yield to increase up to 40-45% relative to only fermenting C6 sugars. C5+C6 mixed sugar fermentation is designed to achieve superior ethanol yields and is particularly attractive in markets with high ethanol demand. It can be sited alone as a greenfield refinery or co-located next to a producer’s existing first-generation plant. Either can make a successful cellulosic ethanol business.

C5+C6 mixed sugar fermentation achieves higher ethanol yields by adding specially developed microorganisms to the fermentation which also includes the C5 sugars.
