Abstract
Microalgae have emerged as promising candidates for third- and fourth-generation biofuels due to their ability to efficiently fix CO₂, accumulate high lipid content, and adapt to extreme environments with minimal resource input. This review critically examines recent advances across the entire microalgae biofuel production chain. It highlights key species with high lipid productivity and strong environmental tolerance, including those capable of thriving in wastewater, saline, and acidic conditions. The review further synthesizes current strategies for enhancing lipid accumulation, encompassing both genetic interventions and environmental manipulations. Innovations in post-harvest processing—such as integrated fermentation, thermochemical conversion, and anaerobic digestion—have also demonstrated improvements in overall biofuel yield and energy recovery. Despite these advancements, challenges related to scalability, cost-effectiveness, and industrial CO₂ integration remain significant barriers to commercialization. This review underscores the importance of continued efforts in strain engineering, direct CO₂ utilization from industrial emissions, and life cycle sustainability assessments, while also highlighting emerging opportunities through systems biology, AI-driven modeling, smart biorefineries, and circular bioeconomy integration to enhance the overall viability and environmental performance of microalgae biofuels in meeting future global energy demands.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
