Sustainable Microalgae Cultivation: A Comprehensive Review of Open and Enclosed Systems for Biofuel and High Value Compound Production
Open accessAbstract
Microalgae have emerged as a promising feedstock for biofuels and high-value compounds, o ff ering potential solutions to global energy and resource challenges. This comprehensive review examines the latest advancements in microalgae cultivation technologies, focusing on both open systems and enclosed photobioreactors (PBRs). We analyze various configurations including open raceway ponds, tubular PBRs, flat panel PBRs, and novel designs such as the Light Exchange Bubble-column (LEB). The review encompasses key performance indicators such as biomass productivity, energy e ffi ciency, and water usage, as well as life cycle assessment (LCA) results for di ff erent cultivation systems. We also discuss the challenges and opportunities in scaling up microalgae production, the potential for integrating wastewater treatment and CO 2 mitigation, and the prospects of biorefinery approaches. By synthesizing recent research findings and identifying knowledge gaps, this review aims to provide a comprehensive understanding of the current state and future directions in sustainable microalgae cultivation for researchers, engineers, and policymakers in the field of renewable energy and biotechnology.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
