Bioethanol

From yeast selection to onsite training Leaf offers conventional bioethanol producers a global fermentation approach to maximize the efficiency and profitability.

Cellulosic ethanol

Leaf was the first to supply a C5 yeast for full scale lignocellulosic ethanol production.

Advanced fermentation services

Capitalizing on our experience in renewable fuels and with the back up of Lesaffre’s fermentation and genetics expertise, Leaf develops economically viable fermentation solutions for deployment within the bio-economy.

Toll Manufacturing

Leaf also provides its expertise and technology to its industrial partners for the manufacturing of their own yeast strain.

Company Overview

Our Products

Cellux™
Cellux™ is Leaf’s selected yeast for lignocellulosic fuel ethanol production.
Ethanol Red®
#1 yeast among conventional fuel ethanol 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).
Safdistil C-70
A very robust yeast strain capable of fermenting various substrates (molasses, C-starch, grains) at different temperatures from 25C to 35C.
Safdistil Plus
Hybrid yeast selected for its superior fermentation kinetic, temperature resistance and alcohol tolerance. Recommended on both sugar (thick juices of various compositions) and starch substrates.
Propaide
Yeast nutrient complex based on the synergies between organic & mineral nitrogen and vitamins. Its formula was specifically developed to enhance yeast growth and secure alcoholic fermentations.
