Chromatin announces dual-purpose hybrid sorghum for sugar and bioenergy production

Chromatin Inc. announced its dual-purpose SweetFuel sorghum hybrids, which combine high yields of both fermentable sugar and biomass per acre. Chromatin’s SweetFuel hybrids are designed to capture the value of sugars produced in sorghum juice as well as the additional value of the energy stored in biomass or bagasse.

Chromatin’s Chief Technology Officer, David Jessen, presented data on SweetFuel hybrids at the International Bioenergy and Bioproducts Conference and BioPro Expo in Atlanta. Speaking in a session on Transformative Technologies, Jessen presented data from sorghum field trials and highlighted the opportunity for Chromatin’s dual-purpose sorghum hybrids to reduce the cost of renewable energy.

Replacing fossil fuels with an energy crop requires a systems approach. Our SweetFuel hybrids make it possible to increase bioenergy value by at least 2-fold over collecting sugar alone—offering sugars for chemical and fuel processes, and high energy biomass for thermochemical conversions.

Jessen also emphasized the potential for future sorghum improvements, including near-term advances from breeding, as well as next-generation designs that will deploy Chromatin’s proprietary gene stacking technology.

Chromatin, Inc. is a privately-held growth stage company that provides technology, seeds and biomass to cleantech and agriculture markets.



There is lots of sorghum grown in the central valley of California. Even if only half of the stalks could be turned into fuel it might provide the state with all the ethanol needed for E10 without imports.


Cellulosic ethanol make sense as long as good farm land is not used to grow feed stocks. Domestic, Industrial, agricultural and forest wastes should be used.


They can use half the sorghum stalks and still have plenty left for the land. They have central valley water from the Sierra snow pack melt to water them and the grain goes to animal feed just as it does now. They do not use more land nor more water, just half the stalks that would have rotted and given off methane in the fields.
