Wood‐Based Bioelectronics: Lignosulfonate‐Based Conductive Biocomposites for Paper Organic Electrochemical Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
Biodegradable wood‐based bioelectronics are realized by integrating poly (2,3‐ethylenedioxythiopene:lignosulfonate (PEDOT:LigS) as a mixed ionicelectronic channel in organic electrochemical transistors fabricated on paper substrates. The biocomposite exhibits high conductivity, biocompatibility, and strong transistor performance, while devices built on

Enzymatic production of lactulose by fed-batch and repeated fed-batch reactor

Bioresource Technology, 2021
The effects of the most significant operational variables on reactor performance of fed-batch and repeated fed-batch were evaluated in the lactulose production by enzymatic transgalactosylation. Feed flowrate in the fed stage (F) and fructose to lactose molar ratio (Fr/L) were the variables that mostly affected the values ​​of lactulose yield (YLu ...

Control of fed-batch fermentations

Biotechnology Advances, 1999
Fed-batch fermentation is used to prevent or reduce substrate-associated growth inhibition by controlling nutrient supply. Here we review the advances in control of fed-batch fermentations. Simple exponential feeding and inferential methods are examined, as are newer methods based on fuzzy control and neural networks.

Fed-batch culture technology

Biotechnology Advances, 1986
The use of fed-batch procedures offers distinct advantages over other modes of operation of bioreactors, and is a widely researched technique. These advantages are discussed; some uses of fed-batch procedures and the associated methods of modelling and control are reviewed.

Fed-batch cultivation of Wautersia eutropha

Bioresource Technology, 2008
Batch kinetics of polyhydroxybutyrate (PHB) synthesis in a bioreactor under controlled conditions of pH and dissolved oxygen gave a biomass of 14 g l(-1) with a PHB concentration of 6.1 g l(-1) in 60 h. The data of the batch kinetics was used to develop a mathematical model, which was then extrapolated to fed-batch by incorporating the dilution due to ...
