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
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
You can obtain the advanced microorganisms from different suppliers to reduce
supply risk of your project.The microorganisms convert both the C6 and the
C5 sugars to ethanol.
C5+C6 mixed sugar fermentation is installed and has been operational since
mid-2013 at Kalundborg demonstration plant after an uncomplicated change to the
process setup. The necessary safety measures are already in place at our
Kalundborg plant and will be as well in your project.
