Tiny Marine Crustacean Assists In Developing Wood Based Biofuel

Scientists from the University of York, University of Portsmouth and the National Renewable Energy Laboratory have discovered an enzyme produced by gribbles, tiny marine wood borers, that can help turn wood based biomass into biofuel. Unlike termites that have microbes inside their guts to help process wood they digest, gribbles have a sterile gut which means that these tiny animals process the wood themselves through an enzyme.

Scientists have now isolated this enzyme and once its structure is studied and can be commercially reproduced, it can help create sustainable liquid biofuels.

Biofuels are sustainable, efficient, and renewable fuels that are processed from biological material called biomass. Biomass are organic material from living or recently living organisms. Biofuels are derived from biological carbon fixation which is the reduction of carbon dioxide or inorganic carbon to organic compounds by living organisms.

Biofuels can come from different sources such as agricultural crops, animal products, plant material or from living organisms like algae.
