Abstract
A new method of producing butyrylcholinesterase (BChE) preparations, stable in storage and use, has been proposed. The BChE preparation is the enzyme co-immobilized with 0.2 M 5-5′-dithiobis (2-nitrobenzoic acid) in starch or gelatin gel. All experimental preparations retain enzyme activity for at least 300 d. The preparations based on gelatin gel show higher activity but lower sensitivity to the toxicants tested in this study compared to the starch gel-based preparations. A method has been proposed for integrated detection of anti-cholinesterase substances in aqueous solutions using the experimental preparation with immobilized BChE. After the additional incubation of the preparation with the immobilized enzyme in the solution of the analyte, the detection limits of malathion and pirimiphos-methyl determined using the IC20 values were below their maximum allowable concentrations—0.005 µM and 0.03 µM, respectively.

Abstract
The present study demonstrates a simple approach to enhancing thermal stability of butyrylcholinesterase (BChE) by using natural polymers. Analysis of thermal inactivation of the tetrameric BChE in starch and gelatin gels at 50–64 °C showed that thermal inactivation followed second-order kinetics and involved two alternating processes of BChE inactivation, which occurred at different rates (fast and slow processes). The activation enthalpy ΔH# and the activation entropy ΔS# for BChE in starch and gelatin gels were evaluated. The values of ΔH# for the fast and the slow thermal inactivation of BChE in starch gel were 61 ± 3, and 22 ± 2 kcal/mol, respectively, and the values of ΔS# were 136 ± 12 and −2.03 ± 0.05 cal∙K−1∙mol−1, respectively. Likewise, the values of ΔH# for BChE in gelatin gel were 58 ± 6 and 109 ± 11 kcal/mol, and the values of ΔS# were 149 ± 16 and 262 ± 21 cal∙K−1∙mol−1, respectively. The values of the activation parameters obtained in this study suggest that starch gel produced a stronger stabilizing effect on BChE exposed to elevated temperatures over long periods compared with gelatin gel.

Abstract
The aim of this research was to design a method of immobilization of high-purity human butyrylcholinesterase on the surface of gold nanoparticles preserving the activity of the enzyme. In order to achieve this aim, the method of fractionation and purification of human butyrylcholinesterase from plasma was modified. The synthesis of 15-nm gold nanoparticles was carried out by citrated method. A method of conjugation of the high-purity butyrylcholinesterase with gold nanoparticles was developed. It was found that the Immobilization of butyrylcholinesterase on the surface of gold nanoparticles resulted in a significant (to 23%) increase in the specific activity of the enzyme.

Abstract
This study shows the development of dry, highly stable immunoassays for the detection of bio warfare agents in complex matrices. Thermal stability was achieved by the lyophilization of the complete, homogeneous, bead-based immunoassay in a special stabilizing buffer, resulting in a ready-to-use, simple assay, which exhibited long shelf and high-temperature endurance (up to 1 week at 100 °C). The developed methodology was successfully implemented for the preservation of time-resolved fluorescence, Alexa-fluorophores, and horse radish peroxidase-based bead assays, enabling multiplexed detection. The multiplexed assay was successfully implemented for the detection of Bacillus anthracis, botulinum B, and tularemia in complex matrices.

Abstract
Increasing attention has been given to nanobiocatalysis for commercial applications. In this study, laccase was immobilized on polyacrylonitrile (PAN) nanofibrous membranes through ethanol/HCl method of amidination reaction and successfully applied for removal of 2,4,6-trichlorophenol (TCP) from water. PAN membranes with fiber diameters from 200 nm to 300 nm were fabricated via electrospinning and provided a large surface area for enzyme immobilization and catalytic reactions. Images of scanning electron microscope demonstrated the enzyme molecules were aggregated on the nanofiber surface. The immobilized laccase exhibited 72% of the free enzyme activity and kept 60% of its initial activity after 10 operation cycles. Moreover, the storage stability of the immobilized laccase was considered excellent because they maintained more than 92% of the initial activity after 18 days of storage, whereas the free laccase retained only 20%. The laccase-PAN nanofibrous membranes exhibited high removal efficiency of TCP under the combined actions of biodegradation and adsorption. More than 85% of the TCP was removed under optimum conditions. Effects of various factors on TCP removal efficiency of the immobilized laccase were analyzed. Results suggest that laccase-PAN nanofibrous membranes can be used in removing TCP from aqueous sources and have potential for use in other commercial applications.

Abstract
Horseradish peroxidase (HRP) from roots of horseradish (Amoracia rusticana) was successfully immobilized on novel enzyme carriers, poly(methyl methacrylate-co-ethyl acrylate) (PMMA CEA) microfibrous membranes, and used for removal of bisphenol A from water. PMMA CEA fibrous membranes (PFM) with fiber diameters of 300-500 nm, were fabricated by electrospinning. HRP was covalently immobilized on the surface of microfibers previously activated by polyethylenimine and glutaraldehyde. HRP loading reached 285 mg/g, and enzyme activity was 70% of free HRP after immobilization. Both stabilities and reusability of HRP were greatly improved after immobilization. After six repeated runs, immobilized HRP retained about 50% of its initial activity. Immobilized HRP exhibited significantly higher removal efficiency for bisphenol A (BPA) in 3h (93%) compared with free HRP (61%) and PFM alone (42%). The high BPA removal can be resulted by improvement of catalytic activity of immobilized HPR with adsorption on modified PMMA CEA support.

Abstract
The kinetics and thermodynamics of the thermal inactivation of polyphenol oxidase (PPO) in an aqueous extract from mushroom Agaricus bisporus (J.E. Lange) Imbach was studied, using pyrocatechol as a substrate. Optimal conditions for enzymatic studies were determined to be pH 7.0 and 35-40 °C. The kinetics of PPO-catalyzed oxidation of pyrocatechol followed the Haldane model with an optimum substrate concentration of 20 mM. Thermal inactivation of PPO was examined in more detail between 50 and 73 °C and in relation to exposure time. Obtained monophasic kinetics were adequately described by a first-order model, with significant inactivation occurring with increasing temperature (less than 10% preserved activity after 6 min at 65 °C). Arrhenius plot determination and calculated thermodynamic parameters suggest that the PPO in aqueous extract from Agaricus bisporus mushroom is a structurally robust yet temperature-sensitive biocatalyst whose inactivation process is mainly entropy-driven.

Abstract
Optimization of thermal processes relies on adequate degradation kinetic models to warrant food safety and quality. The knowledge on thermal inactivation kinetics of antimicrobial peptides is necessary to allow for their adequate use as natural biopreservatives in the food industry. In this work, thermal inactivation of the previously characterized bacteriocin-like inhibitory substance (BLIS) P34 was kinetically investigated within the temperature range of 90-120 degrees C. Listeria monocytogenes ATCC 7644 was used as the indicator microorganism for antimicrobial activity. Applicability of various inactivation models available in the literature was critically evaluated. The first-order model provided the best description of the kinetics of inactivation over the selected temperatures, with k values between 0.059 and 0.010 min(-1). D and k values decreased and increased, respectively, with increasing temperature, indicating a faster inactivation at higher temperatures. Results suggest that BLIS P34 is thermostable, with a z value of 37.74 degrees C and E(a) of 72 kJ mol(-1).
