Functional properties and potential application of ethanol tolerant β-glucosidases from and yeasts.

β-Glucosidases have been extensively investigated to integrate the enzyme complex for cellulose fiber saccharification and for improving the aroma of wine. To produce these enzymes, greater attention has been given to filamentous fungi and bacteria, and few investigations have targeted the potential applications of enzymes secreted by yeasts. Addressing this issue, in this study, β-glucosidases were produced by the and yeasts, via solid state fermentation with wheat bran as a substrate.
