Abstract
A low-cost, stable and non-precious metal catalyst for efficient degradation of tetracycline (TC), one of the most widely used antibiotics, has been developed. We report the facile fabrication of an electrolysis-assisted nano zerovalent iron system (E-NZVI) that achieved TC removal efficiency of 97.3% with the initial concentration of 30 mg L-1 at an applied voltage of 4 V, which was 6.3 times higher than the NZVI system without an applied voltage. The improvement caused by electrolysis was mainly attributed to the stimulation of corrosion of NZVI, which accelerated the release of Fe2+. And Fe3+ in the E-NZVI system could receive electrons to reduce to Fe2+, which facilitated the conversion of ineffective ions to effective ions with reducing ability. Moreover, electrolysis assisted to expand the pH range of the E-NZVI system for TC removal. The uniformly dispersed NZVI in the electrolyte facilitated the collection and secondary contamination could be prevented with the easy recycling and regeneration of the spent catalyst. In addition, scavenger experiments revealed that the reducing ability of NZVI was accelerated in the presence of electrolysis, rather than oxidation. TEM-EDS mapping, XRD and XPS analyses indicated that electrolytic effects could also delay the passivation of NZVI after a long run. This is mainly due to the increased electromigration, implying that the corrosion products of iron (iron hydroxides and oxides) are not formed mainly near or on the surface of NZVI. The electrolysis-assisted NZVI shows excellent removal efficiency of TC and is a potential water treatment method for the degradation of antibiotic contaminants.

Huang Y, Yang J. Kinetics and mechanisms for sulfamethoxazole transformation in the phenolic acid-laccase (Trametes versicolor) system.

Abstract
Oxidation of phenolic acids (PCs) by laccase could produce various kinds of reactive oxygen species (ROS), which is expected to have substantial impact on the transformation of antibiotics like sulfamethoxazole (SMX) in soil and aquatic environments. In this study, the formation of semiquinones radical (SQ●-), superoxide anion radical (O2●-), hydrogen peroxide (H2O2), hydroxyl radical (●OH), and singlet oxygen (1O2) in a laccase-gallic acid (GA) reaction system was confirmed. Meanwhile, GA would be transformed to its monomeric quinone and quinones of di- and tri-polymers. Transformation of SMX by laccase alone is negligible, while which was greatly enhanced in the presence of GA at the optimal pH of 5.5. The dissolved O2 was the requisite for transformation of SMX due to its fundamental role in the formation of SQ●-, the key species initializing the chain reactions for the generation of other ROS. The quenching experiments indicated O2●- and 1O2 were the main ROS responsible for SMX transformation. A total of thirteen products were proposed for the SMX transformation, with the pathways including the breaking of S-N bond, the cleavage of oxazole ring, electrophilic substitution, Michael addition, and condensation reactions. Moreover, the existence of electron-withdrawing substitution group on the benzene ring of PCs and less stability of SQ●- was believed to be favorable for the transformation of SMX. The results above expand our understanding on the role of oxidation of PCs by laccase in the SMX transformation in environments and are of significance in relation to use of laccase in dealing with SMX pollution.

Abstract
In this work we report the effect of incorporating conducting oligophenylenes and a cobaltocene-based redox mediator on photodriven electron transfer between thioglycolic acid (TGA) capped CdS nanorods (NR) and the native nitrogenase MoFe protein (MoFeP) by following the reduction of H+ to H2. First, we demonstrate that the addition of benzidine-a conductive diphenylene- to TGA-CdS and MoFeP increased catalytic activity by up to 3-fold as compared to CdS-MoFeP alone. In addition, in comparing the use of oligophenylenes composed of one (p-phenylenediamine), two (benzidine) or three (4,4''-diamino-p-terphenyl)phenylene groups, the largest gain in H2 was observed with the addition of benzidine and the lowest with phenylenediamine. As a comparison to the conductive oligophenylenes, a cobaltocene-based redox mediator was also tested with the TGA-CdS NRs and MoFeP. However, adding either cobaltocene diacid or diamine caused negligible gains in H2 production and at higher concentrations, caused a significant decrease. Agarose gel electrophoresis revealed little to no detectable interaction between benzidine and TGA-CdS but strong binding between cobaltocene and TGA-CdS. These results suggest that the tight binding of the cobaltocene mediator to CdS may hinder electron transfer between CdS and MoFe and cause the mediator to undergo continuous reduction/oxidation events at the surface of CdS.

Int J Biol Macromol 2021; 176:394-403. [PMID: 33548319 DOI: 10.1016/j.ijbiomac.2021.01.212] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Revised: 01/20/2021] [Accepted: 01/30/2021] [Indexed: 11/28/2022]
Abstract
This study reports an efficient and fast procedure for the purification of laccase (PaL) obtained from the resin of Pistacia atlantica Desf. It was purified by one-step affinity chromatography and showed the specific activity of 393 U/mg with 81.9-fold purification. The molecular weight of PaL was estimated to be approximately 60 kDa using gel electrophoresis SDS-PAGE. Moreover, it depicted diphenolase activity and high affinity towards 2,6-dimethoxy phenol (Km = 10.01 ± 0.5 mM) and syringaldazine (Km = 6.57 ± 0.2 mM) comparing with plant-origin polyphenol oxidases reported in the literature. It should be noted that PaL possessed optimal activity at pH 7.5 and 45 °C. It also remained stable under different conditions of pH (6.5-8.0), temperature (25-45 °C), and when it was exposed to several metal ions. The MTT and flow cytometry assays demonstrated that the enzyme treatment significantly affected growth of HeLa, HepG2, and MDA-MB-231 cells with LC50 values of 4.83 ± 0.02, 61 ± 0.31, and 26.83 ± 0.11 μM after 72 h, respectively. NOVELTY STATEMENT: This is the first attempt to isolate and characterize a new oxidoreductase from the resin of Pistacia atlantica Desf., native species of Iran, to recruit it in cytotoxicity researches. In the purification process by an efficient affinity column (SBA-NH2-GA), the enzyme was eluted promptly with a satisfied yield. The purified laccase exerted higher affinity to diphenolic compounds and pH-thermal stability compared to other plant-derived polyphenol oxidases. The purified enzyme was found to show anti-oxidant capacity and significantly inhibited the growth of cancerous cells in vitro. PaL showed more cytotoxic activity towards HeLa and MDA-MB-231 cells by induction of apoptosis. The cytotoxic activity of the laccase was measured by flow cytometry.

Abstract
Electrolysis was applied to enhance the efficiency of micron-size zero valent iron (mFe0) and thereby promote p-nitrophenol (PNP) removal. The rate of PNP removal by mFe0 with electrolysis was determined in cylindrical electrolysis reactor that employed annular aluminum plate cathode as a function of experimental factors, including initial pH, mFe0 dosage and current density. The rate constants of PNP removal by Ele-mFe0 were 1.72-144.50-fold greater than those by pristine mFe0 under various tested conditions. The electrolysis-induced improvement could be primarily ascribed to stimulated mFe0 corrosion, as evidenced by Fe2+ release. The application of electrolysis could extend the working pH range of mFe0 from 3.0 to 6.0 to 3.0-10.0 for PNP removal. Additionally, intermediates analysis and scavengers experiments unraveled the reduction capacity of mFe0 was accelerated in the presence of electrolysis instead of oxidation. Moreover, the electrolysis effect could also delay passivation of mFe0 under acidic condition, as evidenced by SEM-EDS, XRD, and XPS analysis after long-term operation. This is mainly due to increased electromigration meaning that iron corrosion products (iron hydroxides and oxides) are not primarily formed in the vicinity of the mFe0 or at its surface. In the presence of electrolysis, the effect of electric field significantly promoted the efficiency of electromigration, thereby enhanced mFe0 corrosion and eventually accelerated the PNP removal rates.

Abstract
A biocatalytic system based on laccase functionalized waste-derived iron oxide nanoparticles (LAC-DA-Fe2O3) was designed by a mechanochemical approach and employed in the electrocatalytic reduction of oxygen. Full characterization of the obtained bioconjugates revealed that the protein adopted a partially unfolded state. The mentioned configuration, together with the geometry coordination changes along the T1 center can be further related to a high bioelectrocatalytic response. A current density up to 2.9 mA cm-2 has been achieved, which is among the highest values reported in literature for laccase functionalized nanomaterials.

Abstract
Enzymatic fuel cells may become more accessible for applications powering portable electronic devices by broadening the range of potentially usable fuels and oxidizers. In this work we demonstrate the operation of an integrated, yet versatile multi-substrate biofuel cell utilizing either glucose, fructose, sucrose or combinations of thereof as biofuels, and molecular oxygen originating from solution phase and/or an internal chemical source, as the oxidizer. In order to achieve this goal we designed an enzymatic cascade-functionalized anode consisting of invertase (INV), mutarotase (MUT), glucose oxidase (GOX), and fructose dehydrogenase (FDH), deposited on top of a mesoporous carbon nanoparticle matrix, in which electron relay molecules had been entrapped. The anode was then conjugated to a compatible enzymatic cathode that employs a cascade of catalase (CAT) and bilirubin oxidase (BOD), allowing the cell to operate in an aerobic environment and/or to utilize, under anaerobic conditions for instance, hydrogen peroxide as a source for the oxygen oxidizer. While operated in the presence of the sugar mixture and hydrogen peroxide, the power output of the dually cascaded biofuel cell reaches a peak power density of 0.25 mW cm-2 and demonstrates an open circuit potential of 0.65 V. To our knowledge this is the first reported biofuel cell that discharges with both anodic and cathodic enzymatic cascade architectures and the first biofuel cell that is repeatedly switched between aerobic and anaerobic conditions without any significant decrease in the discharge performance.

Abstract
This paper reports the design and preparation of a biohybrid photoelectrochemical cell (PEC) that can drive the tandem enzymatic oxidation and aldol condensation of n-butanol (BuOH) to C8 2-ethylhexenal (2-EH). In this work, BuOH was first oxidized to n-butyraldehyde (BA) by the alcohol oxidase enzyme (AOx), concurrently generating hydrogen peroxide (H2O2). To preserve enzyme activity and increase kinetics nearly 2-fold, the H2O2 was removed by oxidation at a bismuth vanadate (BiVO4) photoanode. Organocatalyzed aldol condensation of C4 BA to C8 2-EH improved the overall BuOH conversion to 6.2 ± 0.1% in a biased PEC after 16 h. A purely light-driven, unbiased PEC showed 3.1 ± 0.1% BuOH conversion, or ~50% of that obtained from the biased system. Replacing AOx with the enzyme alcohol dehydrogenase (ADH), which requires the diffusional nicotinamide adenine dinucleotide cofactor (NAD+/NADH), resulted in only 0.2% BuOH conversion due to NAD+ dimerization at the photoanode. Lastly, the application of more positive biases with the biohybrid AOx PEC led to measurable production of H2 at the cathode, but at the cost of lower BA and 2-EH yields due to both product overoxidation and decreased enzyme activity.

Abstract
Simultaneously enhancing the catalytic bioactivity and stability of enzyme is still an intractable issue in the enzymatic study. Herein, a facile and effective approach was designed to immobilize and modify laccase on a Cu2+-adsorbed pyrene-terminated block copolymer [poly(acrylic acid)/poly(poly(ethylene glycol) acrylate)] (PAA/PPEGA), which was prepared via well-controlled reversible addition-fragmentation chain transfer polymerization. PAA provided the supporting matrix for firm immobilization of Cu2+, an enzyme bioactivity inducer, onto the microstructure of laccase, while avoiding any contamination of the heavy metal Cu2+ into the following application system. The water-soluble, biocompatible, and nontoxic PPEGA was used as an ideal modifier to improve the laccase stability. Accordingly, the modified laccase exhibited enhanced catalytic bioactivity and stability simultaneously to 447% and 237%, respectively. The modified laccase was immobilized on the highly oriented pyrolytic graphite surface and large-area graphene papers through π-π stacking interactions between the pyrene moiety of PAA/PPEGA and the π-conjugated graphenelike surface. The as-prepared portable solid-state electrochemical laccase biosensor showed lowest detection limit of 50 nM (S/N ≥ 3) and long-term stability for pyrocatechol detection. Besides, the laccase immobilization on graphene paper provided efficient pyrocatechol decontamination platform with convenience and recyclability, which could retain the laccase bioactivity of 176% after 8 consecutive operations.

Abstract
The oxygen reduction reaction is one of the most important chemical processes in energy converting systems and living organisms. Mediator-less, direct electro-catalytic reduction of oxygen to water was achieved on spectrographite electrodes modified by physical adsorption of bilirubin oxidases from Myrothecium verrucaria. The existence of an alternative resting form of the enzyme is validated. The effect on the catalytic cycle of temperature, pH and the presence of halogens in the buffer was investigated. Previous results on the electrochemistry of bilirubin oxidase and on the impact of the presence of halogens are reviewed and reinterpreted.

Abstract
Fully electroactive multilayer architectures combining the redox protein cytochrome c and the enzyme laccase by the use of silica nanoparticles as artificial matrix have been constructed on gold electrodes capable of direct dioxygen reduction. Laccase form Trametes versicolor and cytochrome c from horse heart were electrostatically coimmobilized by alternate deposition with interlayers of silica nanoparticles in a multilayer fashion. The layer formation has been monitored by quartz crystal microbalance. The electrochemical properties and performance of the nanobiomolecular entities were investigated by cyclic voltammetry, indicating, that a multistep electron transfer cascade, from the electrode via cytochrome c in the layered system toward the enzyme laccase, and here to molecular dioxygen was achieved. The response of the novel architecture is based on direct electron exchange between immobilized proteins and can be tuned by the assembly process.

Abstract
Enzymatic biofuel cells (EBFCs) are promising renewable and implantable power sources. However, their power output is often limited by inefficient electron transfer between the enzyme molecules and the electrodes, hindered mass transport, low conductivity, and small active surface area of the electrodes. To tackle these issues, we herein demonstrated a novel EBFC equipped with enzyme-functionalized 3D graphene-single walled carbon nanotubes (SWCNTs) hybrid electrodes using the naturally abundant glucose as the fuel and oxygen as the oxidizer. Such EBFCs, with high stability, can nearly attain the theoretical limit of open circuit voltage (∼1.2 V) and a high power density ever reported (2.27 ± 0.11 mW cm(-2)).
