A global fermentation approach


Yeast is a key ingredient in bioethanol manufacturing directly influencing the plant productivity. The correct strain of yeast must be used in the right presentation, quantity, physiological condition and stage in the process. The bioethanol industry requires continuous innovation and demands yeast strains with higher sugar and ethanol tolerance levels, higher resistance to temperature and lower congeners production. Fermentation products must also be able to resist to the specific stresses of the substrates used for the production of conventional ethanol and ferment sugars with the highest efficiency. Our yeast and yeast products for conventional bioethanol production were selected to meet those expectations.

At Leaf our team of fermentation specialists offer custom made recommendations adapted to the specificities of the process, the needs and the economics of bioethanol producers around the world. From the selection of the yeast strain to the definition of its format up to onsite training of your staff, Leaf offers bioethanol producers a global fermentation approach to maximize their plant’s efficiency and profitability.

Ethanol Red®

#1 yeast among conventional bioethanol producers, Ethanol Red® tolerates high ethanol levels and is ideal for the production of industrial ethanol from starch substrates with a final ethanol concentration of up to 18% (v/v). Displaying a higher yield in ethanol than other yeasts, even at high temperatures Ethanol Red® is also suitable for Very High Gravity (VHG) (up to 36% dry matter) and Simultaneous Saccharification and Fermentation (SSF) processes.

Gen One Plus

Alcohol Yeast for the production of ethanol from traditional starch based raw materials. Gen One + is a specially selected strain of Saccharomyces cerevisiae that has been developed for the Fuel Ethanol Industry using Lesaffre’s patented hybridization techniques. Gen One + is rapid fermenting, temperature tolerant dry yeast that has increased ethanol tolerance, decreased glycerol and displays higher alcohol yields and maintains higher cell viability during fermentation as compared with similar yeast strains in the market. Designed for producing alcohol at elevated temperatures, Gen One + is capable of maximizing alcohol yields under a wide range of temperatures.
