摘要：
Integrated carbon dioxide (CO2) sequestration, wastewater treatment (WWT) and biofuel generation place the microalgae as a promising feedstock at all levels. Though microalgae based biofuels are acknowledged as an alternative and renewable source of energy, mass cultivation and subsequent bioprocessing of microalgal species are the most challenging steps from a technological perspective. Hence, this article attempted to summarise the ecological and bioprocess principles involved in microalgal cultivation, with detailed discussion on various influencing factors for biofuel production. Further, it explored the real trait of microalgae through both thermochemical and biochemical conversion processes for the production of various biofuels such as biodiesel, bioethanol, biomethane, bio-oil, biohydrogen and other products. The integrated zero waste microalgal biorefinery concept was discussed briefly to promote sustainability on the commercial implementation of the microalgal biofuel technology. Future research challenges on microalgal biotechnology for commercial biofuel production were highlighted based on the existing limitations of bioprocess principles. © 2018 Elsevier Ltd
