Laccase Application in Medium Density Fibreboard to prepare a Bio-composite

Laccase efficacy as a biological tool for the removal of lignin in pulp industries is evident and has a scope for a wider application. In this research study, rubber wood (Hevea brasiliensis) fibres were treated with laccase enzyme to study its effect on the fibre surface and the enzyme hydrolysis...
