Ptimization of Co-immobilization of Cellulase and β-glucosidase

IOP Conference Series: Earth and Environmental Science, 2020
Abstract Cellulase can hydrolyze cellulose to produce reducing sugars such as cellobiose and cellotriose. β-glucosidas can further hydrolyze cellobiose and cellobiose produced by cellulase to produce glucose. According to the hydrolysis mechanisms of cellulase and β-glucosidas, we selected two enzyems, cellulase and β-glucosidase to ...

Assessment of in situ immobilization of Lead (Pb) and Arsenic (As) in contaminated soils with phosphate and iron: solubility and bioaccessibility [PDF]

, 2010
The effect of in situ immobilization of lead (Pb) and arsenic (As) in soil with respectively phosphate and iron is well recognized. However, studies on combined Pb and As-contaminated soil are fewer, and assessment of the effectiveness of the ...

Simultaneous immobilization of lead, cadmium and arsenic in soil by iron-manganese modified biochar

Frontiers in Environmental Science, 2023
Cationic lead/cadmium and anionic arsenic exhibit opposite geochemical behaviors in soils, which makes the synchronous remediation of As, Cd, and Pb challenging. In this study, we developed an iron-manganese modified biochar (BC-Fe-Mn) that prepared from

Co-immobilized carrier-free enzymes for lactose upgrading

Current Opinion in Green and Sustainable Chemistry, 2022
Abstract The enzymatic production of lactofructose syrup from lactose coming from surplus whey represents a sound example of circular economy. The production process requires the sequential action of two enzymes, namely β-galactosidase and glucose (xylose) isomerase, which can act independently in different reactors or in a one-pot system. The latter

Simultaneous co-immobilization of glucose oxidase and catalase in their substrates

Applied Biochemistry and Microbiology, 2007
Glucose oxidase (GOD) and catalase (CAT) were simultaneously co-immobilized onto magnesium silicate (florisil) by covalent coupling. Glucose was added in immobilization mixture and hydrogen peroxide which is the substrate of CAT was produced in coupling mixture during immobilization time.

Aroma Release in Wine Using Co-Immobilized Enzyme Aggregates [PDF]

Molecules, 2016
Aroma is a remarkable factor of quality and consumer preference in wine, representing a distinctive feature of the product. Most aromatic compounds in varietals are in the form of glycosidic precursors, which are constituted by a volatile aglycone moiety linked to a glucose residue by an O-glycosidic bond; glucose is often linked to another sugar ...

Recent advances in enzyme immobilization technology

Xi'an Gongcheng Daxue xuebao
As an efficient and safe biocatalyst, enzymes have been widely used in many fields such as food, medicine and environmental governance, but it is difficult to realize further industrial application due to the poor environmental stability of free enzymes.
