Wood waste made into bio-ethanol

Researchers at the Indian Institute of Technology (IIT), Guwahati, and the University of Lisbon, Portugal, have studied the efficacy of a specific bacterial enzyme in breaking down woody bio matter into simple sugars that can be fermented efficiently to produce bio-ethanol, a promising renewable fuel that can replace petroleum-based fuel systems.

The research has been published in the International Journal of Biological Macro-Molecules, PTI reports.

There is interest in developing methods to extract bio-ethanol for fuel from agricultural and forestry residues and crops that are rich in carbohydrate polymers (ligno-cellulose), the plant dry matter that constitutes the woody part of plants. The ligno-cellulose extracted from plants is deconstructed by using the biological catalysts (enzymes) called cellulases, and subsequently fermented.
