“…The effect of these factors at the level of laccase gene transcription has been demonstrated in many fungal species. In most of the reported examples, laccase expression is regulated by an array of factors, often acting in a synergistic way [153][154][155].…”

Laccases (benzenediol:oxygen oxidoreductases, EC 1.10.3.2) are blue multicopper oxidases that catalyze the oxidation of an array of aromatic substrates concomitantly with the reduction of molecular oxygen to water. In fungi, laccases carry out a variety of physiological roles during their life cycle. These enzymes are being increasingly evaluated for a variety of biotechnological applications due to their broad substrate range. In this review, the most recent studies on laccase structural features and catalytic mechanisms along with analyses of their expression are reported and examined with the aim of contributing to the discussion on their structure-function relationships. Attention has also been paid to the properties of enzymes endowed with unique characteristics and to fungal laccase multigene families and their organization.

“…Besides mediators, the use of inducer to enhance laccase production has been widely practiced in fungi especially in the white rots where metals, aromatic compounds, and phenolic compounds (Terrón et al 2004) have been used as inducers. Conversely, there are certain substances which can inhibit the production of laccase and are known as the inhibitors such as sodium azide and dithiothreitol DTT (Additional file 1: Table S2).…”

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".

“…Furthermore, it was observed induction of laccase in G. lucidum exposed to pyrogallol and 2,6-dimethoxyphenol. Terrón et al (2004) reported that aromatic compounds, particularly, p-coumaric acid and guaiacol, increased the production of laccase by Trametes sp. I-62.…”

-(Leaf extracts of Casearia sylvestris and Casearia decandra affect growth and production of ligninolytic enzymes in wood decay basidiomycetes). White-rot basidiomycetes are able to deteriorate wood products and be pathogenic to living trees, requiring, thus requiring control. The tropical flora is an important source of eco-friendly antifungal compounds; however, the knowledge on how leaf extracts affect the fungal physiology is limited. Therefore, in the present work we investigated the influence of ethanolic leaf extracts of Casearia sylvestris and C. decandra at 0.1 mg mL -1 on the production of ligninolytic enzymes by Trametes villosa, Ganoderma australe and Pycnoporus sanguineus. Overall, the extracts inhibited the mycelial growth and the production of biomass. Additionally, C. sylvestris extract reduced the production of manganese peroxidase and laccase; however, the exposure to C. decandra extract resulted in variable responses. Therefore, enzymes related to lignin degradation are potential targets to control wood decay fungi by plant bioactive compounds, as their ability to colonize the substrate may be impaired.

Basidiomicetos de podridão branca são capazes de deteriorar madeira e atuar como patógenos de árvores. A flora tropical é uma importante fonte de compostos antifúngicos ecologicamente seguros, entretanto, o conhecimento de como extratos vegetais afetam a fisiologia fúngica é limitado. Portanto, neste trabalho foi investigada a influência de extratos etanólicos de folhas de Casearia sylvestris e C. decandra, na concentração de 0,1 mg mL -1 , sobre a produção de enzimas ligninolíticas por Trametes villosa, Ganoderma australe e Pycnoporus sanguineus. De modo geral, os extratos inibiram o crescimento micelial e a produção de biomassa. Além disso, o extrato de C. sylvestris reduziu a produção de manganês peroxidase e lacase, porém as respostas ao extrato de C. decandra foram variáveis. Deste modo, enzimas envolvidas na degradação da lignina são alvos potenciais para o controle de fungos causadores de podridão em madeira por compostos vegetais bioativos, uma vez que a capacidade desses microrganismos para colonizar o substrato pode ser prejudicada.
