ACurvularia sp. isolated from soil was found to contain laccase activity toward guaiacol as substrate. The organism produced an extracellular laccase in a medium containing yeast extract, peptone and dextrose. Initial medium pH 4.0 and cultivation temperature 30°C were found to be most suitable for maximum enzyme production. The optimum pH and temperature for laccase activity were found to be 5.2 and 50°C, respectively. Under optimum conditions, the enzyme had aKm (guaiacol) of 0.75 mmol/L and aV of 1.50 CU min−1 ml−1. Some divalent metal ions inhibited laccase activity at very low concentrations.
