The pretreatment generally refers to thedisruption of the naturally resistant carbo-

hydrate-lignin shield that limits the accessibility

of enzymes to cellulose and hemicellulose (Yan

and Wyman, 2008).

The pretrreatmant can be performed (1)

physically e.g mechanical size reduction, ball

milling, compression milling, high temperatur,

high pressure, (2) chemically e.g using sulphuricacid, HCl, H2O2, ozone, l ime, NaOH, (3)

biologically e.g using white rot fungi, or (4)

combination among the three approaches.


23/25



However, the choice of pretreatmenttechnology is not trivial and must take into

account sugar-release patterns and solid

concentrations for each pretreatment in

conjunction with their compatibility with theoverall process, feedstock, enzymes, and

organisms to be applied.

Therefore, researches to find out the bestpretreatment for certain agro-industrial waste

biomass in Indonesia should be carried out

intensively


24/25


COCLUSIO

Since Indonesia has abundant and cheap agro-industrial wastebiomass, productions of the second generation bioethanol from

the biomass are essential in order to overcome our excessive

dependence on petroleum for liquid fuels and also to address the

build-up of greenhouse gases that cause global climate change.

Pretreatment step is the key cost element in the biological

conversion of agro-industrial waste biomass to bioethanol and

must be advanced and carefully integrated with the rest of the

process to realize the full potential of cellulosic ethanol or other

biologically derived products.

It is now time for far more aggressive and intensive to carry out

fundamental and applied researches on the pretreatment step

and its integration with the rest of the second generation

bioethanol process.
