S. Korean researchers develop unique biorefinery system
Q. Korean researchers have developed a unique biorefinery system for creating _____ polymers from natural sources.- Published on 09 Mar 16a. Non—natural
b. Natural
c. Artificial
d. None of the above
ANSWER: Non—natural
The system works to create non natural polymers from natural sources, allowing the creation of plastics in an eco-friendly way. Team from Korea Advanced Institute of Science and Technology/KAIST developed metabolically engineered Escherichia coli strains to synthesise non-natural, biomedically important polymers including PLGA - previously considered impossible to obtain from bio-based materials. Renewable biomass that are non food can replace petrochemical raw materials. Biorefineries that transform non edible biomass into fuel, power, heat and chemicals have received considerable attention as sustainable alternative to fossil fuels.
