How does Lesaffre develop alternatives to biofuels ?

Facing the global warming and the scarcity of fossils energies, Lesaffre invests in its research in biotechnologies to develop fermentations able to provide real alternatives to ethanol fuel. Hence R&D teams of Lesaffre contribute to the reduction of greenhouse gas emissions in order to meet industrials’ needs.

Biofuels or agrofuels : the alternative to ethanol

Bioethanol of first generation is the first alternative to fossil energies. The cellulose contained in sugar plants (beet and cane) associated with the starch contained in wheat, corn or potatoes generates sugar. When this sugar is coupled with yeast, the fermentation process begins. Then the mix is distilled to produce bioethanol.

However, this 1st generation biofuel is drawing on our food resources. In order to limit their use, searches have been focusing on vegetal wastes, straw and wood compost, to produce a 2nd generation alcohol.

The assets of Lesaffre R&D in favour of an ecological ethanol more respectful of the environment

To face up the challenge of fermenting compost, our R&D team already has a lot of undeniable assets: our long standing expertise in alcoholic fermentation, our skills in genetics and our industrialization process. Therefore our R&D department achieved to meet biofuel market demands by reuniting these 3 strengths.

A patented yeast in the production of 2nd generation biofuel

So our teams have built yeasts able to ferment able to ferment 5-carbon sugars. The fusion of one of these yeasts with a yeast resistant to toxics makes the random recombination of yeast genomes with different phenotypes possible. That’s how the R&D of Lesaffre developed CelluX 2, a yeast which can ferment 5-carbon sugars and us resistant to toxics and with a strain adapted to the industrialization of biofuels. 3 patents have been issued from this biotechnology innovation.
