Laccase is an oxidase enzyme, produced from newly isolated fungal strain Aspergillus foetidus. Maximum activity of laccase appeared on the 9th day of inoculation of spores of fungal strain in the liquid culture medium. The activity of laccase detected by UV/VIS spectrophotometer using guiacol as a substrate. The enzymatic characteristic like Km, pH and temperature optimum were reported for this enzyme. https://www.biotech-asia.org/vol7no2/production-of-laccase-from-newly-isolated-fungal-strain-aspergillus-foetidus-3397/ Aspergillus foetidus; Oxidative enzyme; laccase; enzyme unit; temperature optima; pH optima
