On-line Monitoring and Control of Fed-batch Fermentations in Winemaking
CHIMIA, 2016 The fermentation of yeast in fed-batch mode shows great potential in winemaking because it allows the concentration of sugars to be kept low and constant throughout the process which, in turn, reduces cell stress and leads to a significant ...

Different process designs for bioethanol production [PDF]
Alfarama Journal of Basic & Applied Sciences, 2023 Improving the conversion of lignocellulosic residues into bioethanol in this study entails two trends: process design and substrate adding mode. Two methods of process design, separated hydrolysis and fermentation (SHF) and simultaneous saccharification ...

Levan Production in Shake Flask and Fermenter Influence of Feeding Strategy on Levan Yield and Molecular Weight Distribution [PDF]
E3S Web of Conferences, 2023 Effect of feeding strategy on levan production was studied in a shake flask and a 5 L lab scale fermenter. In a shake flask, levan specific substrate yield (YP/S) increased from 0.35 g levan/g sucrose to 0.48 g levan/g sucrose with repeated batch feeding.
