degradation

Catalytic lignin degradation and transformation

A. Peroxidase – Lignin peroxidase (LiP, glycoprotein, high structural

similarity to Cytochrome C peroxidase), Manganese peroxidase (MnP,

structural similarity with LiP), various LiP or MnP mutants

B. Laccase (oxidizes the phenolic units in lignin to phenoxy radicals

leading to aryl-C cleavage)

C. Glyoxal Oxidase (copper radical oxidase, uses the substrates of

glycoaldehyde produced by the oxidation of β-O-4 model substructure

using lignin peroxidase, structural correlation with galactose oxidase)

D. FAD(Flavin Adenine Dinucleotide) Enzymes - Pyranose 2-oxidase, Aryl

alcohol oxidase, Cellobiose dehydrogenase

E. Auxiliary enzymes – methanol oxidase, 1,4-benzoquinone reductase,

methyltransferase, P450, L-phenylalanine ammonia lyase, 1,2,4-

superoxide dismutase, catalase

Chemical and semi-chemical pulping

Basic principles

• Principles of chemical pulping processes

– To achieve fiber separation by lignin removal

– To make lignin to become soluble in the cooking liquor

• Two basic principles

– Formation of hydrophilic groups in lignin • Sulfite process : HSO3

-

– Degradation of lignin to low molecular weight fragments• Soda and kraft processes

Kraft vs. Sulfite process

Recent pulping process

• Organosolv process

– Alcell process (Canada)

• Autohydrolysis of wood components in an ethanol and water solution

– Organocell process (Germany)

• Methanol-AQ process
