文摘
- •
An innovative high cell density bioprocess for Scheffersomyces stipitis was developed.
- •
Feasible cell reusability was possible at elevated flocculent biomass concentration.
- •
Acid treatment was an effective and safe action for flocculation disruption.
- •
The decrease in temperature was related to upper xylose consumption and EtOH productivity.
- •
A short-term adaptation was achieved, reflected by increased aldo-keto reductase activity.
