bioethanol yeast strains
Vu sur ethanolproducer.com
however, there are some challenges in yeast fermentation which inhibit ethanol production such as high temperature, high ethanol concentration and the ability to ferment pentose sugars. various types of yeast strains have been used in fermentation for ethanol production including hybrid, recombinant and wildtype yeasts
