Monoculture-based microalgae cultivation systems to treat wastewater are well-reported. Despite that, this method has some limitations in terms of nutrient removal potential, environment adaptation, and low biomass productivity. Conversely, microalgae co-cultivation and a two-stage sequential cultivation system (TSSCS) recently emerged as a promising approach to improve the treatment process and biomass productivity through better adaptation to the environment.

The cultivation was performed inside a specifically designed low-cost photobioreactor (PBR) system. A microalgal consortium 2:1 was developed using Tetraselmis indica (TS) and Picochlorum sp.

- Advances in carbon dioxide sequestering tech are crucial for addressing climate change, and converting CO into useful products or renewable fuels can help mitigate its negative effects.
- Microalgae stand out as a viable option due to their efficient photosynthesis and ability to generate biomass for valuable products, though high cultivation costs and lower CO sequestration rates are current challenges.
- The manuscript discusses optimizing microalgal CO sequestration while generating valuable products, exploring novel methods like genetic manipulation and AI, and reviewing the potential benefits and hurdles of these technologies for achieving net-zero CO emissions.
Article Synopsis
- * Optimized conditions included a 12-hour day-night cycle, pH around 7.0 with aeration, which maximized biomass production and nutrient removal efficiency from the wastewater.
- * Results suggested that this method could effectively use municipal wastewater to produce biofuels and other valuable products while improving environmental sustainability.
Article Synopsis
- The study focuses on improving biomass productivity in the microalgal strain sp. BDUG 100241 by testing different growth conditions: photoautotrophic, mixotrophic, and heterotrophic.
- The best growth was observed in mixotrophic conditions with glucose, where the use of sodium acetate as a carbon source resulted in the highest biomass production and biomolecule accumulation.
- Specifically, a sodium acetate concentration of 7.5 g/L yielded the highest biomass (2.40 g/L) and lipid content (53.50%), indicating it as the most effective organic carbon source for this strain.
Article Synopsis
- * Traditional wastewater treatment methods are not very effective, making microalgae like Tetraselmis sp. a promising solution for removing contaminants and heavy metals while producing valuable biomass.
- * The review emphasizes the potential of using bioreactor systems to enhance the efficiency of Tetraselmis sp. in wastewater treatment and discusses future research directions and applications for its biomass.
Microalgae is a renewable bioresource with the potential to replace the conventional fossil-based industrial production of organic chemicals and pharmaceuticals. Moreover, the microalgal biomass contains carotenoids, vitamins, and other biomolecules that are widely used as food supplements. However, the microalgal biomass production, their composition variations, energy-intensive harvesting methods, optimized bio-refinery routes, and lack of techno-economic analysis are the major bottleneck for the life-sized commercialization of this nascent bio-industry.

Therefore, enormous efforts have been considered to move-out from fossil fuels to renewable energy sources based industrial process developments. Recently, biohydrogen (bio-H) has been recognised as a clean source of fuel with high-energy efficiency, which can be produced via different routes.
