Fungi produce various types of extracellular enzymes, including the copper-containing oxidative enzyme laccase. This enzyme uses gaseous oxygen (O 2) as an electron acceptor to catalyze oxidation of phenolic compounds, and therefore it can act as a cathode biocatalyst in a microbial fuel cell (MFC). In this study, a new model of the air-cathode microbial fuel cell (AC-MFC) was constructed. For its design, the laccase-producing yeast Galactomyces reessii cultured in potato dextrose agar was grown in the cathode chamber, and an anaerobic microbial community was maintained in the anode chamber in order to carry out sulfate removal and, simultaneously, generate electricity. Results showed that the cathode with G. reessii outperformed the cathode with sterile gel (negative control), yielding the maximum open circuit voltage of 550.65±14.92 mV, the maximum power density of 0.35±0.01 mW/m 3 , the maximum current density of 225.69±17.25 mA/m 3 and sulfate removal of 73.29±1.31%. This study demonstrated the feasibility of using a yeast culture for continuous laccase production in the cathode chamber of the AC-MFC in order to improve their electricity generation and sulfate removal.

“…The solution was centrifuged at 5,000 rpm for 5 mins for the separation of microbial cells and sawdust from the enzyme. The supernatant was collected and used for laccase activity determination according to Lin et al [4]. Briefly, the 0.5 mL of the crude enzyme was mixed with 0.2 mL of 0.02 M ABTS (2, 2-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid)) and 2.3 mL sodium acetate buffer.…”

To solve this problem, some researchers used a bio-cathode with laccase [3][4].Laccase, also known as bezenediol: oxygen oxidoreductase (EC 1.10.3.2), is a blue multicopper oxidase found in plants, insects, fungi, and bacteria.

Electrical energy is critical in the area of healthy development. Conventional fossil fuel resources such as natural gas, petroleum, and coal have met this energy demand. Because of the global insufficiency of fossil fuels, renewable energy sources appear to be a better alternative [1]. Various renewable energy sources, such as solar, hydropower, wind, geothermal, and biomass, have been studied in terms of energy generation [2].A microbial fuel cell (MFC) is a green device that utilizes microbial metabolism to convert chemical energy in organic matter to electrical energy (Slate et al. 2019). However, due to the high cost of its components, such as a platinum-coated electrode, this innovation still has some limitations. To solve this problem, some researchers used a bio-cathode with laccase [3][4].Laccase, also known as bezenediol: oxygen oxidoreductase (EC 1.10.3.2), is a blue multicopper oxidase found in plants, insects, fungi, and bacteria. It has the ability to catalyze the oxidation of both phenolic and non-phenolic compounds [5][6]. The fungal laccase is well known among microbial laccases for a variety of field applications as well as fiber property improvement,

“…1a, b, 2a, b, Supplementary material). Lin et al (2018) added laccase from Ganoderma lucidum to the broth in the cathode chamber, favouring the redox reaction, and obtained 84% of COD removal in the anode chamber and a power density of 40 mW cm 2 , maintaining electricity energy for 45 days. Kacem et al (2017) immobilised commercial laccase in polymer inclusion ionic liquid membranes and applied it in single-chamber air-cathode MFC obtaining a COD removal rate of 70%, in fresh wastewater collected from a mineral oil manufacturing company.…”

Microbial fuel cell-induced production of fungal laccase to degrade the anthraquinone dye Remazol Brilliant Blue R

et al. 2019

The anthraquinone dye Remazol Brilliant Blue R is largely used in the textile industry. However, its removal from wastewaters is costly and complex. Many methods have been tested to solve this ecological problem, but there is still a need for efficient methods. We propose here an alternative use of a two-chambered microbial fuel cell (MFC), fuelled with domestic wastewater in the anodic chamber, to degrade a simulated textile dye effluent made of Remazol Brilliant Blue R inoculated with an immobilised fungal strain, Pleurotus ostreatus URM 4809, as a laccase producer, in the cathodic chamber. The MFC showed continuous synthesis of laccase in the cathodic chamber, which, in turn, promoted the rapid decolourisation, of more than 86% of the textile dye effluent. The yield was further increased by the addition of glycerol. Electrochemical monitoring also indicated an increase in power density and current density. After 20 days of MFC operation, 62.1% of organic matter was removed in the anodic compartment, thus leaving the effluent with a much lower toxicity.
