Over the past three decades, organic reactions catalyzed by lipase have been extensively studied. To overcome drawbacks of free enzymes and develop new sustainable biocatalysts, various insoluble forms lipases were examined. Especially interesting are immobilized on silica nanoparticles (SiNPs) due to their promising unique advantageous physicochemical properties. Therefore, present paper presents an overview different functionalization methods SiNP surfaces create a more favorable...
Two anthraquinonic dyes, C.I. Acid Blue 225 and Violet 109, were used as models to explore the feasibility of using horseradish peroxidase enzyme (HRP) in practical decolorization dyes wastewater. The influence process parameters such concentration, hydrogen peroxide temperature, dye pH was examined. temperature activity profiles similar for both dyes. Under optimal conditions, 94.7% 109 from aqueous solution decolorized (treatment time 15 min, concentration 0.15 IU/mL, 0.4 mM, 30 mg/L, 4,...
The quest for sustainable biomaterials with excellent biocompatibility and tailorable properties has put polyhydroxyalkanoates (PHAs) into the research spotlight. However, high production costs lack of bioactivity limit their market penetration. To address this, poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) was combined a bacterial pigment strong anticancer activity, prodigiosin (PG), to obtain functionally enhanced PHBV-based biomaterials. samples were produced in form films...
Lipase-catalyzed organic reactions have been widely practiced in the past three decades. Especially interesting are insoluble/immobilized forms due to providing a possibility of facile use and recyclability, thus reducing process costs, making procedure more environmentally friendly. Carbon-based supports extensively exploited for this purpose, because neutral biodegradable nature thermal chemical stability. Their high specific surface area, characteristic morphology lower mass transfer...
Abstract BACKGROUND In this work, fumed nano‐silica ( FNS ) was chemically modified to amino AFNS and subsequently cyanuric chloride CCAFNS silica tested for the immobilization of lipase from Candida rugosa CRL ). The effects initial enzyme concentration, time buffer ionic strength on were investigated in order optimize utilization support determine mechanism immobilization. most active preparations used examine thermal operational stability. RESULTS amount immobilized increased with...
Amino modified nonporous fumed nano-silica particles was used for the development of efficient nanobiocatalysts application in biosynthesis bioactive galactosides, galacto-oligosaccharides (GOS).
Horseradish roots ( Armoracia rusticana ) fresh extract was the source of unpurified horseradish peroxidase (HRP) which used for immobilization in a form cross‐linked enzyme aggregates (CLEAs). Among three precipitants used, acetone appeared to be best choice precipitation. Acetone with 2% glutaraldehyde gave recovery 30.3% initial activity. immobilized (HRP–CLEAs) showed remarkable efficiency Acid Violet 109 (AV 109) oxidation. Under optimal conditions (pH 4, dye concentration 30 mg L −1 ,...
BACKGROUND In this study, in order to obtain the best support for immobilization of lipase from Candida rugosa (CRL), procedure chemical modification fumed silica nanoparticles (FNS) with (3-Glycidyloxypropyl)trimethoxysilane (GOPTMS) was optimized by varying amount GOPTMS used and duration modification. To evaluate prospects FNS surface on process, activity thermal stability immobilized GFNS compared cyanuric chloride functionalized amino (CCAFNS). RESULTS The epoxy (GFNS) 400–500 µmol...
The problem of environmental pollution day by becomes more worrisome, primarily due to the large amounts wastewater contaminated with various harmful organic compounds, discharged into environment untreated or partially clean. Feasibility use horseradish peroxidase (Amoracia rusticana) in synthetic dyes decolorization was approved many researchers. Among a number supports used for immobilization, it found that natural clay, kaolin has excellent features which are precondition obtaining...
The increasing pollution from the textile industry, particularly organic azo dyes, presents a significant environmental challenge, necessitating development of effective and sustainable treatment methods. This study investigates adsorption potential hazelnut shells (raw—RHSs; modified—MHSs) for removal dyes aqueous solutions. As biomass, are biodegradable represent alternative to synthetic adsorbents, thereby reducing ecological footprint. Through series batch experiments, influence various...
Conformational stability of various 5-substituted orotic acid derivatives was studied by applying linear free energy relationships (LFER) to the 13C NMR chemical shifts. The correlation analysis for substituent-induced shifts (SCS) with inductive (σI), and resonance (σR) parameters were carried out through Single Substituent Parameter (SSP) Dual (DSP) methods, multiple regression analysis. Good Hammett correlations all carbons obtained, while electrophilic substituent constants better fitted...
The substituent and solvent effect on intramolecular charge transfer (ICT) in 5-arylidene-3-methyl-2,4-thiazolidinediones (series 1) 5-arylidene-3-phenyl-2,4-thiazolidinediones 2) was studied by using experimental theoretical methodology. of specific non-specific solvent–solute interactions the UV–vis absorption maxima shifts evaluated Kamlet-Taft Catalán parameter sets. Linear free energy relationships (LFERs) have been applied to 13C NMR data SSP (single parameter) DSP (dual parameters)....
