Influence of iron and copper on the activity of laccases in Fusarium oxysporum f. sp. lycopersici

Hernández-Monjaraz, Wendy Susana; Caudillo-Pérez, César; Salazar-Sánchez, Pedro Ulises; Macías-Sánchez, Karla Lizbeth.
Braz. j. microbiol; 49 (supl.1), 2018
ABSTRACT Fusarium oxysporum f. sp. lycopersici is a phytopathogenic fungus that causes vascular wilt in tomato plants. In this work we analyze the influence of metal salts such as iron and copper sulphate, as well as that of bathophenanthrolinedisulfonic acid (iron chelator) and bathocuproinedisulfonic a...

Combined strategies for improving production of a thermo-alkali stable laccase in Pichia pastoris

Wang, Jiayi; Lu, Lei; Feng, Fujuan.
Electron. j. biotechnol; 28 (), 2017
Background: Laccases are copper-containing enzymes which have been used as green biocatalysts for many industrial processes. Although bacterial laccases have high stabilities which facilitate their application under harsh conditions, their activities and production yields are usually very low. In this wo...

Preliminary studies of new strains of Trametes sp. from Argentina for laccase production ability

Fonseca, María Isabel; Tejerina, Marcos Raúl; Sawostjanik-Afanasiuk, Silvana Soledad; Giorgio, Ernesto Martin; Barchuk, Mónica Lucrecia; Zapata, Pedro Darío; Villalba, Laura Lidia.
Braz. j. microbiol; 47 (2), 2016
Abstract Oxidative enzymes secreted by white rot fungi can be applied in several technological processes within the paper industry, biofuel production and bioremediation. The discovery of native strains from the biodiverse Misiones (Argentina) forest can provide useful enzymes for biotechnological purpos...

Influence of initial pH of the growing medium on the activity, production and genes expression profiles of laccase of Pleurotus ostreatus in submerged fermentation

Díaz, Rubén; Téllez-Téllez, Maura; Sánchez, Carmen; Bibbins-Martínez, Martha D; Díaz-Godínez, Gerardo; Soriano-Santos, Jorge.
Electron. j. biotechnol; 16 (4), 2013
Background: Enzymatic activity and laccase isoenzymes number of Pleurotus ostreatus grown in different pH values of the growing medium in submerged fermentation and incubated in buffer solutions of different initial pH values were determined. The expression profiles of five laccase genes (Lacc1, Lacc4, L...
