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.

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 ...

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,

Integrated CO2 capture and enzymatic bioconversion in supported ionic liquid membranes

Separation and Purification Technology, 2012
Abstract This work proposes an innovative concept for the removal of CO2 from flue gas streams using supported liquid membranes with non-volatile ionic liquids (or solvents), comprising a thermoresistant enzyme that enhances the selective transport of CO2. Membrane stability, CO2 and N2 permeability and CO2/N2 ideal selectivity was determined in the

Enzymatic pretreatment to enhance anaerobic bioconversion of high strength wastewater to biogas: A review

Science of The Total Environment, 2020
Oil and grease, carbohydrate, protein, and lignin are the main constituents of high strength wastewaters such as dairy wastewater, cheese whey wastewater, distillery wastewater, pulp and paper mill wastewater, and slaughterhouse wastewaters. These constituents have contributed to various operational problems faced by the high-rate anaerobic bioreactor (

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
