Heavy metal wastewater often contains multiple ions, and competition among them reduces the adsorption efficiency of microalgae. Enhancing this is crucial for improving heavy removal. This study optimized lysine addition to facilitating formation a ternary complex between microalgae, lysine, metals, thereby enhancing in both single- mixed-metal systems. In single-metal system at 64 mg/L, improved removal rates copper, zinc, cadmium by 13.96%, 41.21%, 33.26%, respectively. binary systems (Cu-Zn, Cu-Cd, Cu-Pb) 32 increased copper 11.81%, 15.71%, 25.25%, while cadmium, lead 15.41%, 12.51%, 3.93%, Competitive analysis revealed that most strongly inhibited adsorption, significantly suppressed zinc adsorption. Mechanistic investigations using 3D-EEM, FTIR, XPS demonstrated humic substances extracellular polymeric (EPSs) microalgae play key role binding. interaction increases number carboxyl functional groups on cell surface, microalgae’s capacity adsorb metals.

Besides biomass production, some microalgae have been used to treat wastewater contamination. However, in general, high concentrations of heavy metals significantly inhibit algal growth. We thus need find ways promote the resistance metals, increase their growth rate under stress, and achieve coupling metal removal production simultaneously. In this review, mechanisms for by are proposed. Effects exogenous chemical additives (dissolved organic matters, formaldehyde, sulphate, phosphate, nitric oxide donors, etc.) on biosorption summarized. Genetic manipulation microalgal strain selection strategies also introduced, especially acid-tolerant strains with efficiencies Cr(VI) Cd2+ at low pH conditions. Recent advances (semi)continuous heavy-metal-bioremediation biomass-production coupled system immobilized microalgae, as well challenges solutions commercialization industrialization were discussed.

Osteosarcoma (OS) is one of the most common malignant tumors in children and young adults. As chemotherapy other therapies are limited by low therapeutic efficiency, severe side effects single function, it high value to develop innovative for precise efficient treatment OS. Herein, natural photosynthetic microalgae (C. vulgaris, CV) were utilized as carriers chemotherapeutic agent doxorubicin (DOX) create a multifunctional platform (CV@DOX) photo-modulation tumor microenvironment (TME) synergistic chemo-photodynamic therapy osteosarcoma. CV@DOX exhibited rapid drug release behavior acidic TME, improving efficiency against reducing on normal tissues. Under 650 nm laser irradiation, demonstrated ability effectively generate oxygen alleviate hypoxia utilize photosensitizing properties chlorophyll CV produce an increased amount reactive species (ROS), thereby enhancing photodynamic (PDT). CV@DOX-mediated efficacy halting progression orthotopic osteosarcoma mouse model promoting cell apoptosis, inhibiting proliferation angiogenesis. Moreover, chlorophyll-assisted fluorescence imaging enabled monitoring distribution after administration. Finally, did not cause significant hematological tissue toxicity, prevented DOX-induced cardiotoxicity, showing good vivo biocompatibility. Overall, this work presents novel TME-responsive TME-modulating imaging-guided multimodal treatment.
