Polyaniline nanofiber coated monolith reactor for enzymatic bioconversion

Journal of Molecular Catalysis B: Enzymatic, 2010
Abstract The monolith reactor has many advantages over other reactors including good mass transfer, low-pressure drop and high enzyme stability. In this study, an enzyme-coated monolith with high enzyme stability and activity was developed. The monolith surface was coated with polyaniline nanofibers containing glucose oxidase immobilized on its ...

Bioconversion of food and lignocellulosic wastes employing sugar platform: A review of enzymatic hydrolysis and kinetics

Bioresource Technology, 2022
Bioenergy and biochemicals can be sustainably produced through fermentation and anaerobic digestion (AD). However, this bioconversion processes could be more economical if the hydrolysis rates of substrates in bioreactors can be accelerated. In this review, the feasibilities of including enzymatic hydrolysis (EH) in various bioconversion systems were ...

Three different examples of enzymatic bioconversion in liquid membrane reactors

Enzyme and Microbial Technology, 1987
Abstract Three different examples of enzyme emulsions are presented. The enzymes are immobilized in liquid surfactant membranes. The effect of the organic membrane phase is discussed as well as the influence of the membrane composition on the transport of substrates and products through the membrane. An enzyme emulsion system for the production of l

Bioconversion of cellulose-containing raw material. Enzymatic hydrolysis of cellulose (review)

Proceedings of the Komi Science Centre of the Ural Division of the Russian Academy of Sciences, 2022
Lignocellulose is the most abundant biopolymer on earth. The hydrolysis of lignocellulose to fermentable sugars is a prerequisite for its successful use as a substrate for the large-scale production of value-added industrial products. Enzymatic hydrolysis of lignocellulose is carried out by cellulases, hemicellulases, and ligninases in synergy or ...

Novel Split Intein-Mediated Enzymatic Channeling Accelerates the Multimeric Bioconversion Pathway of Ginsenoside

ACS Synthetic Biology, 2022
Cascade reaction systems, such as protein fusion and synthetic protein scaffold systems, can both spatially control the metabolic flux and boost the productivity of multistep enzymatic reactions. Despite many efforts to generate fusion proteins, this task remains challenging due to the limited expression of complex enzymes.

High-efficiency bioconversion of kitchen garbage to biobutanol using an enzymatic cocktail procedure

Bioresource Technology, 2017
Research on methods to produce biobutanol production from kitchen garbage (KG) as a potential substrate is thus far lacking. Here, the effect of various enzymatic hydrolysis procedures (EHP) was first tested using different enzyme cocktails, on the decomposition of KG. The efficiency of Clostridium acetobutylicum-mediated biobutanol production was then

Extractive bioconversions in aqueous two‐phase systems: Enzymatic hydrolysis of casein proteins

Biotechnology and Bioengineering, 1992
AbstractPartition coefficients in poly(ethylene glycol)/dextran aqueous two‐phase systems are reported for mixed‐casein and its components, α, β and κ casein. Rates of casein proteolysis by α‐chymotrypsin and by trypsin are reported in single‐phase and aqueous two‐phase reactor systems. The advantages resulting from selective partitioning of substrates,
