APPLICATION IN PAPER INDUSTRY
ORGANISMS:PAPER-INDUSTRY,Wood-rotting fungi: a) sapstain ascomycete (Ophiostomaangusticollis) forming dark perithecia with long narrow necksreleasing the ascospores when growing on eucalypt (E. globulus)wood; and b) white-rot basidiomycete (Phlebia chrysocrea) formingyellow-colored effused basidioma on wood (Laurelia philipiana)
Schematic representation of the molecular structures ofenzymes of interest for pitch biocontrol: a Candida rugosa lipase-2(PDB entry 1GZ7) forming a multienzymatic complex (Mancheno etal. 2003); and b Trametes versicolor laccase (PDB entry 1GYC)showing the catalytic coppers as blue spheres (Piontek et al. 2002).Regions with different secondary structure corresponding to helices(red) and β-sheets (yellow) are indicated

Immobilized Enzyme SystemsEnzyme Immobilization:
To restrict enzyme mobility in a fixed space.
Immobilized Enzyme Systems
Entrapment - Matrix Entrapment - Membrane
Entrapment
(microencapsulation)
Surface immobilization
Physical Adsorption: Van der Waals Carriers: silica, carbon nanotube, cellulose, etc. Easily desorbed, simple and cheap, enzyme activity unaffected.
- Ionic Binding: ionic bonds Similar to physical adsorption. Carriers: polysaccharides and synthetic polymers having ion-exchange centers
Cross-linking
Immobilized Enzyme Reactors
Recycle packed column reactor: - allow the reactor to operate at high fluid velocities.
