Abstract :
Microalgal biofuel production is limited by high costs. This study shows that timed antioxidant supplementation 1 mM sodium ascorbate (SE) on day 3 significantly boosts lipid productivity in Phaeodactylum tricornutum. SE treatment increased biomass by 10 % and total lipids by 40 %, especially C16:0 and C16:1 fatty acids. Mechanistically, SE triggered chloroplast ROS accumulation and enhanced antioxidant defenses (higher VC levels and APX/CAT/SOD activities). This response reduced PUFAs but increased overall lipid yield. Transcriptomics revealed two key mechanisms: (1) upregulation of glycolysis genes supplying lipid precursors, and (2) transient nitrogen metabolism activation (6 h), followed by downregulation (24 h), redirecting carbon toward lipid biosynthesis. Notably, the nitrate transporter NRT showed dynamic regulation. These results highlight SE's dual role in oxidative stress modulation and metabolic reprogramming, providing a cost-effective strategy to enhance algal biofuel production.

Abstract :
Microalgae have emerged as multifunctional biofactories capable of simultaneously supporting carbon capture, renewable energy production, environmental remediation, and the synthesis of high value bioproducts. Despite this promise, large-scale deployment remains limited by techno-economic barriers, particularly the high costs of biomass harvesting and dewatering. Recent advances including bioflocculation, magnetic separation, and solarassisted drying are helping to reduce energy inputs and enhance feasibility. In parallel, breakthroughs in synthetic biology, such as CRISPR/Cas genome editing, are enabling the development of engineered strains with enhanced lipid, carbohydrate, and hydrogen productivity. Innovations in photobioreactor design have further improved light-use efficiency, reduced contamination risks, and supported high-density cultivation. Life cycle assessments indicate that integrating microalgal systems with flue gas utilization and wastewater treatment can substantially lower freshwater use and greenhouse gas emissions. To unlock the full potential of this technology, future efforts should prioritize modular biorefinery systems, intelligent process control, and supportive policy frameworks that incentivise negative-emission technologies. These integrated strategies can help position microalgae as a key enabler of a sustainable, circular bioeconomy.

Abstract :
As global energy demand increases and reliance on fossil fuels becomes unsustainable, hydrogen presents a promising clean energy alternative due to its high energy density and potential for significant CO2 emission reductions. However, current hydrogen production methods largely depend on fossil fuels, contributing to considerable CO2 emissions and underscoring the need to transition to renewable energy sources and improved production technologies. Life Cycle Analysis (LCA) is essential for evaluating and optimizing hydrogen production by assessing environmental impacts such as Global Warming Potential (GWP), energy consumption, toxicity, and water usage. The key findings indicate that energy sources and feedstocks heavily influence the environmental impacts of hydrogen production. Hydrogen production from renewable energy sources, particularly wind, solar, and hydropower, demonstrates significantly lower environmental impacts than grid electricity and fossil fuel-based methods. Conversely, hydrogen production from grid electricity primarily derived from fossil fuels shows a high GWP. Furthermore, challenges related to data accuracy, economic analysis integration, and measuring mixed gases are discussed. Future research should focus on improving data accuracy, assessing the impact of technological advancements, and exploring new hydrogen production methods. Harmonizing assessment methodologies across different production pathways and standardizing functional units, such as '1 kg of hydrogen produced, ' are critical for enabling transparent and consistent sustainability evaluations. Techniques such as stochastic modelling and Monte Carlo simulations can improve uncertainty management and enhance the reliability of LCA results. © 2025 The Authors

Abstract :
Retrograde signaling regulates plant senescence, but the role of vacuoles in this process remains unclear. Here, we demonstrate that rice vacuolar H+-ATPase subunit A (OsVHA-A) localizes to both the cytoplasm and nucleus. Sucrose treatment increased OsVHA-A expression and nuclear accumulation, while darkness reduced it. Methyl jasmonate (MeJA) initially promoted OsVHA-A nuclear translocation but decreased it upon prolonged exposure. Downregulation of OsVHA-A expression accelerated MeJA-induced rice leaf senescence but delayed darkness-induced senescence. MeJA treatment also significantly upregulated the expression of OsMYC2 and OsMAPK6 in OsVHA-A-RNAi plants compared to wild-type plants. Moreover, OsVHA-A downregulation notably increased the level of expression of genes associated with sugar signaling and transport under dark conditions. Immunoprecipitation-mass spectrometry and molecular docking analyses identified interactions between OsVHA-A and OsTPR1, OsMed14, sucrose transporters, and enzymes involved in sucrose metabolism. The binding of OsVHA-A with OsTPR1 and OsSUS1 was confirmed by BiFC. These findings highlight the multifunctional role of OsVHA-A in coordinating organelles and nuclear signaling, providing new insights and potential strategies for manipulating senescence to improve rice yield and quality.

Abstract :
pH treatment promotes single-cell lipid accumulation and significantly affects microalgae growth. This study investigates the correlation between lipid content and environmental pH using the model diatom Phaeodactylum tricornutum (P. tricornutum). We compared three distinct pH treatment strategies-continuous, intermittent, and a two-phase culture-in P. tricornutum. Rigorous analysis of chlorophyll content, cell density, and lipid content indicated that ongoing pH treatment at pH 9.5 (CHES) emerged as the most effective approach for lipid accumulation in P. tricornutum. The CHES buffer treatment significantly boosted total lipid yield and led to a reduction in protein content. Carbohydrate content experienced a slight decline under CHES buffer treatment, but changes were observed in the activities of key enzymes. Specifically, [acyl-carrier-protein] S-malonyltransferase (MAT) activity decreased after 3 days in the control treatment, while no significant change was noted under the CHES buffer treatment. In contrast, diacylglycerol O-acyltransferase (DGAT) activity showed upregulation 2 and 3 days post-CHES buffer treatment. Moreover, the study identified differentially expressed genes enriched in Gene Ontology (GO) terms associated with protein biosynthesis, photosynthesis, nucleoside metabolism, and transferase activity. These outcomes underscore the pivotal role of CHES buffer in orchestrating primary metabolism, potentially steering carbon flux towards lipogenesis. As a result, the potential of microalgae as a sustainable source of biofuels contributes significantly to the transition towards a more environmentally friendly energy landscape.
