Bioethanol
Renewable Environmental friendly Not compete with food and feed Unblended bioethanol fuel or Blended with gasoline
C2H5OH + 3 O2 2 + 3 H2O + heat

First Generation Bioethanol
Ethanol from sugar (sugarcane, etc) and amylum (starch, casava, corn, etc).

Pretreatment

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).

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
-
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)
