Interest in microalgae-derived products is growing, mostly due to their unique characteristics and range of industrial applications. To obtain different products, one must employ specific pretreatments that retain the properties of the biologically active compounds extracted from microalgae biomass; thus, new extraction techniques require frequent upgrades. Due to increased interest in economically viable and ecologically friendly processes, new extraction methods that can be incorporated into microalgae biorefinery systems have become the main focus of research. Therefore, this review aims to address the potential applications, future prospects, and economic scenario of the new physicochemical treatments used in the extraction of bioactive microalgae compounds.

This study investigated the efficacy of two microalgae treatment systems (Chlorella vulgaris monoculture and a Chlorella vulgaris-S395-2-Clonostachys rosea symbiotic system) in treating aquaculture wastewater, under varying concentrations of synthetic strigolactone analog (GR24). By exposing the systems to four GR24 doses (0, 10, 10, and 10 M), we examined the impact on biomass growth, photosynthesis, and wastewater treatment. Elevated GR24 concentrations bolstered metabolism and photosynthesis in the systems, fostering rapid symbiont growth and enhanced treatment efficiency.

Microalgae-bacteria symbiosis system is significant for sustainable and low-carbon wastewater treatment, with self-aggregation being key to its stable operation and effective pollutant removal. Cellular motility is the main driving force behind self-aggregation, crucial for symbiosis stability, but the characteristics and patterns involved still remain largely unexplored. Here, cellular movement dynamics into the microalgae-activated sludge model (ASM3) is incorporated, enabling synchronized simulation of metabolic activities and movement behaviors through physical and biochemical interactions in bioreactor systems.

This study explores the role of α-Fe₂O₃ in improving extracellular electron transfer (EET) and symbiotic interactions between electroactive Shewanella oneidensis MR-1, its gene-deficient mutants (ΔmtrC, ΔomcA, and ΔcymA), and microalgae (Chlorella vulgaris). The iron oxide facilitates the efficient transfer of electrons generated by MR-1 to microalgal photosystem via the pathway of CymA-MtrC-OmcA to α-Fe₂O₃. This process enhances the removals of TOC, TN, and NH₄⁺-N in the MR-1 bacterial-algal consortium by 9.

Nanoplastics (NPs) in marine ecosystems have garnered increasing attention for their interference with the physiological processes of aquatic organisms. An in-depth examination of the toxicological responses of Nannochloropsis oceanica, a species vital to marine ecosystems, is essential due to the crucial role of lipid metabolism in carbon sequestration and energy allocation in microalgae. This study analyzed the toxicological responses of N.
