Aktivitas Enzim Ligninolitik Jamur dari Tandan Kosong Kelapa Sawit (Elaeis guineensis Jacq.)

Abstract

Lignin is a natural polymer and an important compound of plant cell wall constituent. A study about degradation of lignin in environmental has been received considerable attention because it has more complex structure and difficult to be degraded compared to degradation of others plant cell wall constituent. A study to determine the activity of ligninolytic enzyme (Lignin Peroxidase, Manganese Peroxidase and Laccase) of fungi isolated from oil palm empty fruit bunch had been done with screening of ligninolytic activity using potato dextrose agar added with tannin acid (0,1%), showed that two out of five fungal isolates have ligninolytic activity. The highest activity of Lignin Peroxidase produced by SN 2 isolate (9,677U/ml), whereas the highest activity of Manganese Peroxidase and Laccase produced by SN 3 isolate by the value of 1,942 U/ml and 1,846 U/ml respectively.
