Abstract
Microalgae is a promising organism as the feedstock of the next generation biofuels, as well as high value nature products, such as astaxanthin, normally under certain stress cultivation conditions. With the clear industrialization targets, there have been two waves of microalgae R&D from the last century and showed obvious energy-driven trends. The overall R&D came into a valley now, however, the promising is still there. So here, from the industrialization point of view, the patent evolution concerning the microalgae for biofuels in the second wave were reviewed and summarized. These technology information will help the scientists to join together with industry to drive the next boost.
Highlights
After the second wave of microalgae R&D, the patent evolution during the last 20 years were quickly reviewed for the reference to the boost of microalgae industrialization
The higher cost of microalgae cultivation and relative low oil price caused the cease of the first wave in 1995 (Sheehan et al, 1998)
The accumulation on strains and numerous technologies helps the form of the second wave while the crude oil price dramatically increased in the early of 21 century
