Glossary

Biomass

Plant matter of recent (nongeologic) origin.

Cellulase

One or more enzymes that catalyze the reaction of water with cellulose to release shorter glucose oligomers and ultimately monomeric glucose sugar.

Cellulose

A glucose polymer composed of up to about 15,000 glucose molecules covalently joined by β 1–4 linkages in long, straight chains that can hydrogen bond with parallel cellulose chains to form crystalline regions. About 35–50% of the structural portion of plants is cellulose.

Cellulosic biomass

Also known as lignocellulosic biomass, the structural part of plants that is not edible by humans and contains cellulose, hemicellulose, pectin, and lignin. Examples include grass, wood, and agricultural and forestry residues.

Cellulosic ethanol

Ethanol made from lignocellulosic biomass by biological, chemical, or chemo-biological processes.

Enzymes

Proteins produced by living cells or organisms that are able to catalyze chemical reactions in organic substances.

Ethanol
