Summary: This study fills the gap in feasibility studies of microalgae process chain through a techno-economic assessment of microalgae (Phaeodactylum tricornutum) production. The results show that artificial light is indispensable for microalgae production in Norway, while more favorable climatic conditions in southern Spain can improve productivity and reduce costs. Additionally, reducing the cost of equipment like photobioreactors and greenhouses, increasing efficiency, and expanding the temperature range of cultivation can further reduce costs.

Summary: The nutrient content of a commercial seawater culture medium for growing Isochrysis galbana was optimized using a genetic algorithm-based stochastic strategy, which significantly improved polyunsaturated fatty acids (PUFAs) productivity by 15% and increased carotenoids by 50% dry weight. The genetic algorithm approach also allowed for the reduction of nutrient requirements, such as N (25%), Mo (20%), Mn (60%), Co (60%), and Cu (60%).

Summary: Sustainable aviation fuels (SAFs) can reduce greenhouse gas emissions compared to conventional fuel. The resources for SAFs have shifted from oil crops to agricultural waste and now to microalgae. Microalgae are the best feedstock for jet biofuel production due to their productivity and carbon dioxide capturing capability. However, microalgae-based biofuel faces the limitation of a high freezing point. A recently developed jet biofuel derived from Euglena wax ester has attracted attention for its low freezing point. Challenges remain in improving production yields and conducting techno-economic analysis. Valorization of industrial byproducts, such as food wastes, will ensure economic viability of biofuel production.

Summary: The study presents techno-economic analyses of high-yield production of furans from mixed-sugar hydrolysates using a hybrid enzyme-chemo-catalytic process. Through a series of reactions and extractions, lignocellulosic mixed-sugar hydrolysates are converted to HMF and furfural, providing a promising price point for industrial production. Sensitivity analyses show that feedstock sugar cost and overall furan yield are key factors influencing the minimum furan selling price, with improvements in these parameters potentially making the price competitive for fuel and polymer precursor applications.

Summary: The objective of this study is to identify the techno-economic factors for the recent hydrogen production pathways and their relevant infrastructures so that the costs reported in the recent articles be easily identified for further analysis. The comparison of the levelised cost of hydrogen production (LCOH) from the steam reforming process and renewable electricity-based electrolysis processes has shown that process efficiency improvement, feedstock price, and requirement of scaling up of newer investments are the key areas of attention. Lower LCOH will encourage the end-users to adopt the newer technology for energy production, which will effectively manage the environmental sustainability targets.

Summary: Poly(3-hydroxybutyrate) (PHB) is a potential bioplastic compound with the ability to reduce production costs. This study explores the financial viability of producing 10,000 tonnes of PHB using open raceway ponds and solvent extraction. The results show a negative net present value and a minimum selling price of $18,339 USD per tonne. Various hypothetical scenarios were examined to increase economic feasibility, resulting in a minimum selling price of $7704 USD per tonne, still twice the current market value of PHB.

Summary: This study investigated the production of PBS from food waste and evaluated critical factors. The economic feasibility of the process was assessed, including the MSP of PBS and sensitivity analysis. The 1,4-butanediol price and solvent usage significantly affected economics. The MSP of PBS was 3.5 $/kg in this process. Monte Carlo simulation determined the uncertainty in the MSP. The plant's ROI, payback period, IRR, and NPV were 15.79%, 6.33 years, 16.48%, and 58,879,000 USD, respectively. Environmental impact factors were evaluated, showing lower GHG emissions compared to conventional PBS production.

Summary: This study investigates the effect of phosphorus limitation on Se accumulation and uptake efficiency in N. oceanica for the first time. Se accumulation increased up to 16-fold and Se uptake efficiency increased up to 3.6-fold under phosphorus growth-limiting concentrations. N. oceanica was then cultivated in a bioreactor with two phosphorus growth-limiting concentrations, analyzing the accumulation of Se in the microalgal biomass and its presence in the spent medium. This study is the first to explore the effect of phosphorus limitation on increasing Se accumulation in microalgae and preventing the release of Se in wastewater.

Summary: The urge for food security and sustainability has driven the development of microalgal biotechnology. Microalgae, as microorganisms, have the potential to be a valuable resource for food, feed, energy, and chemicals. With faster growth and higher productivity than plant crops, microalgae have the advantage of not requiring agricultural land and having efficient fertilizer uptake. They are also seen as a replacement for soy protein, fish oil, and palm oil, and can be utilized in industrial biotechnology for various purposes.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
