海洋微細藻類を用いたバイオ燃料・バイオ製品生産の全経路（種選定・培養・脂質抽出・燃料変換・持続性評価）を2020〜2025年の査読論文で統合的にレビューした研究。Nannochloropsis等の海洋属や開放池・フォトバイオリアクター等の培養戦略を比較し、収穫・脱水・下流処理がエネルギー消費とコストの主要因となり大規模商業化を制約すると結論づける。技術・経済・環境性能を改善するための研究優先課題を提示する。
English
This review integrates 2020–2025 peer-reviewed work across the full marine microalgal biorefinery pathway, from species selection and cultivation to lipid extraction, bioenergy conversion, and sustainability assessment. Comparing genera such as Nannochloropsis and cultivation systems including open ponds and photobioreactors, it finds harvesting, dewatering, and downstream processing dominate energy use and cost, limiting commercialization. It identifies research priorities to improve technical, economic, and environmental performance.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではバイオ燃料の国産供給・エネルギー安全保障やGX推進の文脈で微細藻類研究が注目されるが、本稿は技術レビューでありSSBJ・有報開示や政策制度との直接接続は薄い。日本の藻類バイオ燃料関係者にとっては、収穫・下流コストという商業化の律速点を整理する基礎資料として有用。
In the global GX context
For global GX scholarship, this adds a systems-level synthesis of where marine algal biofuels lose economic and carbon viability — mainly downstream dewatering and processing — which matters for transition-finance and LCA-based accounting of advanced biofuels under frameworks like CSRD and ISSB. It offers little on disclosure infrastructure itself but informs the evidence base for biofuel sustainability claims.

📄 Abstract（原文）
Abstract: Marine microalgae are being investigated as feedstocks for biofuel and bioproduct production because many marine taxa can accumulate lipids while being cultivated in seawater or saline media, reducing dependence on freshwater resources. However, the economic and environmental performance of marine microalgal biorefineries depends strongly on biomass productivity, lipid content, cultivation conditions, harvesting requirements, downstream energy demand, and co-product recovery. Although recent studies have examined cultivation, lipid recovery, and fuel conversion, they often discuss these advances separately, making it difficult to assess the marine microalgal biorefinery as an integrated system. This review examines peer-reviewed studies published between 2020 and 2025 that cover the full production pathway, from species selection and cultivation to lipid extraction, bioenergy conversion, and sustainability assessment. The review focuses on marine genera such as Nannochloropsis, Tetraselmis, and Phaeodactylum tricornutum, as well as cultivation strategies including open ponds, photobioreactors, hybrid systems, low-cost media, and two-phase protocols that enhance lipid accumulation under abiotic stress while maintaining satisfactory biomass productivity. The review also compares open raceway ponds and closed photobioreactors, summarizes recent developments in harvesting and lipid extraction technologies, and evaluates findings from techno-economic analyses and life-cycle assessments. Across the published literature, harvesting, dewatering, and downstream processing are major contributors to energy consumption and production costs, limiting large-scale commercialization. By integrating evidence from upstream cultivation and downstream processing, this review identifies current knowledge gaps and highlights research priorities that could improve the technical, economic, and environmental performance of marine microalgal biofuel production.
