13. Pretreatment of Lignocelullose
Mosier et al. (2005)
Pretreatment:
• Mechanical
• Physical
• Chemical
• Biological
• Combination
Pretreatments have as a goal
to improve the digestibility of
the lignocellulosic biomass
(Hendriks and Zeeman, 2008).
14. Advantages and Disadvantages
Advantages Disadvantages
• No chemical added • Take more times
• Less energy used • Need more places
• More environmental
friendly
Biological pretreatment of EFB by white-rot fungi
compared with physical/chemical pretreatment
15. White-rot Fungi
Enzymes produced by
lignocellulytic fungi:
• Laccase
• Mangan Peroxidase (Mn P)
• Lignin Peroxidase (Li P)
White-rot fungi are the only known organisms
that, to any extent, mineralize lignin to CO2
and water in pure culture (Gold and Alic, 1993)
