“…They have the capability to supply electricity to devices which requires low energy input. The advantages associated with bio-fuel cells are that the enzyme coat are cheap and economically feasible, replacement is easy and convenient (Nazaruk et al 2008), and the activity can be performed at room temperature, neutral pH (Fig. 4) (Kulys and Vidziunaite 2003).…”

Laccases belongs to multinuclear copper-containing oxidase and can act on a variety of aromatic and non-aromatic compounds. Due to their broad substrate specificity, they are considered as a promising candidate in various industrial and biotechnological sectors. They are regarded as a "Green Tool"/"Green Catalyst" in biotechnology. The present review focuses on structure, reaction mechanism, categories, applications, economic feasibility, limitations, and future prospects of fungal laccases. Thus, this review would help in understanding laccases along with the areas, which has not been focused and requires attention. Since past, immense work has been carried out on laccases: yet, new discoveries and application are ever increasing which includes bio-fuel, bio-sensor, fiber board synthesis, bioremediation, clinical, textile industry, food, cosmetics, and many more. Hence, it can be stated that fungal laccase is an enzyme which is "discovered but yet undiscovered".

“…Recently, we reported biocatalytic dioxygen reduction catalyzed by laccase with ABTS as mediator, both ABTS and laccase incorporated into liquid crystalline cubic phase. [16,17,20] ABTS exhibited reversible electrochemistry at a potential close to the formal potential of laccase and good mediating properties in the cubic phase. In the present work, the carbon nanotubes with adsorbed or covalently bound ABTS are used with the aim of enhancing the stability and improving the parameters of the laccase based biocathode.…”

Glassy carbon electrodes modified with films composed of a network of single-wall carbon nanotubes (SWCNTs) and liquid-crystalline cubic phase were used for dioxygen reduction catalyzed by laccase. In the presence of pristine SWCNTs, the overpotential of dioxygen reduction was decreased by 0.5 V (E 1/2 ¼ À 0.09 V). Adding laccase to the system shifted the potential of oxygen reduction to þ 0.52 V vs. Ag/AgCl reference electrode. Carbon nanotubes increased the electrode working area and improved the conductivity of the film. The current density of oxygen reduction was further enhanced by using a common mediator, 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonate) diammonium salt (ABTS). Two procedures for modifying carbon nanotubes with ABTS were compared: by adsorption and by covalent binding. Covalent binding of ABTS to the nanotubes is advantageous since it completely eliminates leaching of mediator to the solution and leads to a stable biocathode system.

“…glucose as the fuel and enzymes as the electrocatalysts, can be utilized at the electrode (Halámková et al, 2012;Zebda et al, 2009;Nazaruk et al, 2008;Togo et al, 2008). Various kinds of enzyme proteins, such as families of dehydrogenases, oxidases, peroxidases, etc., have been examined as the electrocatalysts both of the anode and the cathode, thus, the fuel cell reaction proceeds via a wide variety of the chemical reaction and the electron transfer process at the electrode in the field of BFCs (Rasmussen et al, 2012;Prakash et al, 2009;Drobov et al, 2008;Brunel et al, 2007;Kamitaka et al, 2007;Ikeda and Kano, 2003;Tsujimura et al, 2001;Katz et al, 1999;Gorton et al 1999;Palmore et al, 1998).…”
