Sacarificação e isomerização simultâneas de dextrina na produção de xarope de frutose por ação sinérgica de CLEAs magnéticos de amiloglicosidase e Sweetzyme®
(Universidade Federal de São Carlos, 2019-07-25)
High fructose syrup is a sweetener widely used as a substitute for sucrose by the food and beverage industry. It has many advantages such as relative sweetness superior to sucrose, high solubility, crystallization resistance ...
Estudo da produção de etanol a partir de xilose e xilooligômeros usando xilanases, xilose isomerase e levedura co-imobilizadas
(Universidade Federal de São Carlos, 2019-04-24)
The production of ethanol from xylose with the yeast Saccharomyces cerevisiae was initiated in the group with the SIF process (simultaneous isomerization and fermentation). This process allows total conversion of xylose, ...
