Abstract
Corn (Zea mays) is a commodity of food crops that are important after rice in Indonesia. Corn plantation produces waste in the form of corncob. Corncob is lignocellulosic biomass that can converted to cellulose, even sugar or another chemical like ethanol. The first step for utilization of corncob is delignification. The purpose of this study was to isolate and purify the enzyme laccase from white rot fungus Cerrena sp.B.Md.T.A.1 that inoculation in GDP media used for biodelignification of corncobs. Enzymatic biodelignification conduct with the variation of substrate was 5%, 10%, and 15% (w/v), while the time variation were 6 hours and 24 hours. The percentage of lignin concentration before pretreatment reached is 37.25%. The highest reduction of lignin content was achieved in 15% substrate for 24 hours incubation time around 42.71%.
