Duckweed biofuel

Spirodela polyrhiza, living in pond, differs in their development from terrestrial plants in their morphology and physiology. They do mainly vegetative growth called fronds in spring and summer time, while they switch into a dormant phase represented by turions in autumn and winter due to nutrition starvation and freezing temperature. Interestingly, their dormant phase is characterized with high starch content compared to growth phase with low starch, and as such, represent a high-impact biofuel feedstock that is ripe for exploitation.
