Abstract
Biodevices in which biomolecules such as enzymes and antibodies are immobilized on the surface of electrode materials are capable of converting chemical energy into electrical energy, and are expected to contribute to solving energy problems and developing medical measurements especially as biobatteries and biosensors. Device performance depends on the interface formed between the biomolecule layer and electrode material, and the interface is required to simultaneously achieve a highly efficient enzymatic reaction and electron transfer. However, when enzymes were immobilized on a material surface, the enzymes undergoes a structural change due to the interaction between the enzyme and the electrode surface, making it difficult to maximize the function of the enzyme molecule on the material surface. In this study, we postulate that the structural change of the enzyme would be reduced and the electrochemical performance improved by making the contact area between the enzyme and the electrode extremely small and adsorbing it as a point. Therefore, we aimed to develop a high-power biodevice that retains enzyme structure and activity by interposing gold nanoparticles (AuNPs) between the enzyme and the electrode. The enzymatic and electrochemical properties of pyrroloquinoline quinone-dependent glucose dehydrogenase adsorbed on AuNPs of 5-40 nm diameter were investigated. We found that the characteristics differed among the particles, and the enzyme adsorbed on 20 nm AuNPs showed the best electrochemical characteristics.

Abstract
Enzymes from hyperthermophilic archaea are potential candidates for industrial use because of their superior pH, thermal, and long-term stability, and are expected to improve the long-term stability of biofuel cells (BFCs). However, the reported multicopper oxidase (MCO) from hyperthermophilic archaea has lower redox potential than MCOs from other organisms, which leads to a decrease in the cell voltage of BFCs. In this study, we attempted to positively shift the redox potential of the MCO from hyperthermophilic archaeon Pyrobaculum aerophilum (McoP). Mutations (M470L and M470F) were introduced into the axial ligand of the T1 copper atom of McoP, and the enzymatic chemistry and redox potentials were compared with that of the parent (M470). The redox potentials of M470L and M470F shifted positively by about 0.07 V compared with that of M470. In addition, the catalytic activity of the mutants towards 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) increased 1.2-1.3-fold. The thermal stability of the mutants and the electrocatalytic performance for O2 reduction of M470F was slightly reduced compared with that of M470. This research provides useful enzymes for application as biocathode catalysts for high-voltage BFCs.

Abstract
Ecological and efficient alternatives to industrial processes have sparked interest for using microorganisms and enzymes as biocatalysts. One of the difficulties is finding candidates capable of resisting the harsh conditions in which industrial processes usually take place. Extremophiles, microorganisms naturally found in "extreme" ecological niches, produce robust enzymes for bioprocesses and product development. Thermophiles like Geobacillus, Alyciclobacillus, Anoxybacillus, Pyrococcus and Thermoccocus are some of the extremophiles containing enzymes showing special promise for biocatalysis. Glutamate dehydrogenase used in food processes, laccases and xylanases in pulp and paper processes, nitrilases and transaminases for pharmaceutical drug synthesis and lipases present in detergents, are examples of the increasing use of enzymes for biocatalytic synthesis from thermophilic microorganisms. Some of these enzymes from thermophiles have been expressed as recombinant enzymes and are already in the market. Here we will review recent discoveries of thermophilic enzymes and their current and potential applications in industry.

Construction of a novel bioanode for amino acid powered fuel cells through an artificial enzyme cascade pathway. Biotechnol Lett 2019; 41:605-611.

Abstract
OBJECTIVE The construction of a novel bioanode based on L-proline oxidation using a cascade reaction pathway comprised of thermostable dehydrogenases. RESULTS A novel multi-enzymatic cascade pathway, containing four kinds of dehydrogenases from thermophiles (dye-linked L-proline dehydrogenase, nicotinamide adenine dinucleotide (NAD)-dependent Δ1-pyrroline-5-carboxylate dehydrogenase, NAD-dependent L-glutamate dehydrogenase and dye-linked NADH dehydrogenase), was designed for the generation of six-electrons from one molecule of L-proline. The current density of the four-dehydrogenase-immobilized electrode, with a voltage of + 450 mV (relative to that of Ag/AgCl), was 226.8 μA/cm2 in the presence of 10 mM L-proline and 0.5 mM ferrocene carboxylate at 50 °C. This value was 4.2-fold higher than that of a similar electrode containing a single dehydrogenase. In addition, about 54% of the initial current in the multi-enzyme cascade bioanode was maintained even after 15 days. CONCLUSIONS Efficient deep oxidation of L-proline by multiple-enzyme cascade reactions was achieved in our designed electrode. The multi-enzyme cascade bioanode, which was built using thermophilic dehydrogenases, showed high durability at room temperature. The long-term stability of the bioanode indicates that it shows great potential for applications as a long-lived enzymatic fuel cell.
