Chlorinated organic pollutants constitute a significant category of persistent due to their widespread presence in the environment, which is primarily attributed expansion agricultural and industrial activities. These are characterized by persistence, potent toxicity, capability for long-range dispersion, emphasizing importance eradication mitigate environmental pollution. While conventional methods removing chlorinated encompass advanced oxidation, catalytic bioremediation, utilization biochar has emerged as prominent green efficacious method recent years. Here we review biochar's role remediating typical organics, including polychlorinated biphenyls (PCBs), triclosan (TCS), trichloroethene (TCE), tetrachloroethylene (PCE), organochlorine pesticides (OCPs), chlorobenzenes (CBs). We focus on impact material properties adsorption mechanisms organics. This highlights use sustainable eco-friendly pollutants, especially when combined with biological or chemical strategies. Biochar facilitates electron transfer efficiency between microorganisms, promoting growth dechlorinating bacteria mitigating toxicity organics through adsorption. Furthermore, can activate processes such oxidation nano zero-valent iron, generating free radicals decompose compounds. observe broader application bioprocesses treating soil, reducing impacts. Conversely, water-based integrating proved more effective, leading superior purification results. contributes theoretical practical pollutants.

Published: Jan. 30, 2025

The efficient and cost-effective harvesting of food-grade Euglena gracilis remains a critical challenge in microalgal food production. This study presents an innovative, food-safe approach integrating pH preconditioning, chitosan biopolymer flocculation, green light irradiation to leverage E. gracilis’ natural phototactic behavior. Response surface methodology optimized the parameters (pH 6.49, 46.10 mg·L−1 chitosan, 60 min light), achieving 93.07% biomass recovery, closely matching predicted 92.21%. synergistic effects pH-modified flocculation phototaxis significantly enhanced efficiency compared conventional methods. Notably, harvested cells maintained substantial photosynthetic capability, as evidenced by chlorophyll fluorescence analysis, ensuring preservation nutritional quality. Economic analysis revealed exceptional cost-effectiveness at 2.35 USD per kg dry weight harvested. method’s use non-invasive stimulation ensures product safety while minimizing environmental impact. sustainable economical offers promising solution for industrial-scale production demonstrating potential applicability other microalgae species.
