cleaning. However, there are other technological obstructions to overcome such as
bacterial contamination and co-fermentation of C5 and C6 sugars (Brethauer and
Wyman 2010 ).
Inspite of several challenges, we can see commercial plants coming up for
biofuel production such as IneosBio, Iogen, Kior, Inbicon Coskata, Clariant, Beta-
Renewable, and Dupont. Among these, Beta Renewables and Dupont are based on
cellulosic ethanol production and can be suitably used in our Indian scenario as are
based on multiple feedstocks.

7 Conclusion

Biofuels are no more a fantasy like in last decade but are real at present time.
Lignocellulosic biomass is the only foreseeable source of raw materials for
renewable energy source. After bioconversion of lignocellulosic biomass into its
precursor molecules, glucose can be exploited for other value-added products also
which is all possible theoretically, though some technological gaps persist. Avail-
able feedstock from agriculture and other sources are about 180 million tons per
year, so literally no dearth of such biomass. Second-generation biofuels have the all
potential to meet the need of transport sector. Commercial plants coming up
globally for cellulosic ethanol production as well as other biofuel are an indication
of successful research toward developing such technology; however, we need to
wait for a while to see the economic feasibility and sustainability.
