日本語

本研究では、微細藻類Haematococcus pluvialisの培養において、バイオマス濃度に応じた重炭酸ナトリウムの給餌ポリシーを最適化し、炭素損失を最小化してバイオマス生産性と炭素回収効率を向上させる手法を提案した。2時間間隔の給餌戦略を基に、15分間隔の戦略へと改良し、炭素供給と細胞取り込みの同期を改善した。

English

This study proposes an optimized NaHCO3 feeding strategy for microalgal cultivation to enhance biomass productivity and carbon capture efficiency. By linking specific growth rate to biomass concentration, a daily carbon demand is determined and distributed into feeding intervals, minimizing carbon losses. The strategy was refined from 2-hour to 15-minute intervals, improving synchronization between carbon supply and cellular uptake.

📄 Abstract（原文）

These data illustrate the calculation framework employed to define a daily gradient-based 2-h NaHCO₃ feeding policy as a function of the dynamically evolving biomass concentration, and its subsequent refinement to a 15-min interval strategy, aiming to minimize carbon losses and maximize biomass productivity in Haematococcus pluvialis cultures grown in a 3 L photobioreactor. Specifically, the fed-batch policy at 2-h intervals was developed based on experimental data of biomass production and carbon sequestration under carbon-sufficient conditions (continuous 0.5 % and 1 % CO₂ supply during photosynthetic cycles). By linking the specific growth rate (μ) with total biomass concentration (TB) and the utilized carbon (UC) with produced biomass (PB), a biomass-dependent daily carbon demand was determined, which subsequently distributed into 2-h feeding intervals. The minimum carbon dosage was calculated considering the decrease in dissolved carbon concentration due to the dissociation of NaHCO₃ and the associated CO₂ release. Finally, based on biomass production and carbon sequestration under the 2-h feeding policy, a 15-min NaHCO₃ feeding strategy was developed, re-evaluating the carbon doses, resulting in improved synchronization between carbon supply and cellular uptake and reduced CO₂ losses.
