Laccase activity can be affected by pH and temperature. In this study, the determination of fractionated laccase activity was investigated in order to obtain higher laccase activity than crude extract activity. Determination of laccase activity was carried out using a spectrophotometer with a wavelength of 420 nm. The results the highest activity was obtained at pH 5,5 and a temperature of 60⁰C.enTrichodermaasperellumlaccasepH, temperatureArticle
