Hydrolysis of Penicillin G by Penicillin G Acylase Immobilized on Chitosan Microbeads in Different Reactor Systems
(Wiley-VCH Verlag Gmbh, Weinheim, 2011)
The kinetic parameters for penicillin G hydrolysis in systems with penicillin G acylase from Escherichia coli (free and immobilized on activated chitosan microbeads produced by electrostatic extrusion) were determined. The ...
Ionization energies of K2X (X=F, Cl, Br, I) clusters
(Wiley, Hoboken, 2011)
The electronic structure and properties of dipotassiummonohalides are important for understanding the unique physical and chemical behavior of MnX systems. In the present study, K2X (here X=F, Cl, Br, I) clusters were ...
Compost of Aquatic Weed Myriophyllum spicatum as Low-Cost Biosorbent for Selected Heavy Metal Ions
(Springer International Publishing Ag, Cham, 2014)
Aquatic weed Myriophyllum spicatum L. is one of the most invasive water plants known. In many countries, it is usually harvested and landfilled, where aerobic and anaerobic decomposition takes place. In this research, the ...
Encapsulation of Lactobacillus rhamnosus in Polyvinyl Alcohol for the production of L-(+)-Lactic Acid
(Process Biochemistry, 2021)
Poly(vinyl alcohol) (PVA) was investigated as a carrier for Lactobacillus rhamnosus ATCC 7469 cells for application in L-(+)-lactic acid (LA) fermentation on low-cost food industry by-products. Brewer?s spent grain (BSG) ...
Positron lifetimes in pores of some low-silica zeolites: influence of water content, crystal size and structural type
(Springer, Dordrecht, 2013)
Positron annihilation lifetime spectroscopy has been used for observation of the free voids in low silica zeolites, of LTA and FAU structure and different crystal size, before and after their heating at different temperatures ...
The Electrochemical Investigation of Inclusion Complexes of Nifedipine and Amlodipine with beta-Cyclodextrin and (2-Hydroxypropyl)-beta-Cyclodextrin
(Electrochemical Science Group, Beograd, 2013)
The electrochemical behavior of inclusion complexes of nifedipine (Nif) and amlodipine (Aml), a long-acting calcium channel blockers dihydropyridine (DHP) class, with beta-cyclodextrin (beta CD) and (2-hydroxypropyl)-bet ...
Evaluation of antioxidative effects of twelve 3-substituted-5,5-diphenylhydantoins on human colon cancer cell line HCT-116
(Tubitak Scientific & Technical Research Council Turkey, Ankara, 2013)
Antioxidant effects of twelve 3-substituted-5,5-diphenylhydantoins in concentrations of 0.01, 0.1, 1, 10, and 100 mu M on human colon cancer cell line HCT-116 were determined 24 h after treatment. The concentrations of ...
New facile one-pot synthesis of S-alkyl thiolcarbamates from xanthogenate in water
(Springer Wien, Wien, 2013)
A simple and efficient one-pot synthesis was developed for the preparation of S-alkyl thiolcarbamates from xanthogenate without catalyst using water as a solvent. The water can be recycled after removal of the product. The ...
Reactivation of a thermostable lipase by solid phase unfolding/refolding Effect of cysteine residues on refolding efficiency
(Elsevier Science Inc, New York, 2011)
Lipase from Geobacillus thermocatenulatus (BTL2) was immobilized in two different matrixes. In one derivative, the enzyme was immobilized on agarose activated with cyanogen bromide (CNBr-BTL2) via its most reactive superficial ...
