The wastewater bioremediation is an emerging research area to meet the existing/increasing water crisis challenges. Heavy metals persist in bodies, which can bioaccumulate food chain and cause serious health environmental problems. deteriorating effects of heavy both on human environment have drawn great attention become a major study. Phycoremediation one most promising areas being explored currently. conventional methods such as chemical precipitation, ion exchange, membrane filtration, floatation, coagulation-flocculation electrochemical inherit limitations bringing down cost treatment, increasing efficiency formation toxic sludge secondary pollution. phycoremediation serves be green technology. This review highlights current advances using different species microalgae treat various industrial effluents mechanism removal from them. A comprehensive look into microalgae-based systems (MBSs) has been covered assess through extracellular intracellular mechanisms biosorption, bioaccumulation detoxification metals. It brings focus all technologies times that utilised urban systems. In addition, challenges, bottlenecks future prospects are also discussed with achieving circular bioeconomy management.

Effective Microbial Strategies to Remediate Contaminated Agricultural Soils and Conserve Functions

Agronomy, Год журнала: 2024, Номер 14(11), С. 2637 - 2637

Опубликована: Ноя. 8, 2024

The growing global emphasis on sustainable agriculture has brought increased attention to the health and productivity of soils, especially through lens soil microbiology. Microbial communities in are essential for nutrient cycling, organic matter decomposition, maintaining overall health. However, agricultural practices, including synthetic fertilizers intensive farming, have led short time impacts these microbial ecosystems, potentially threatening fertility environmental quality. Agricultural expansion food production generate waste chemical inputs, such as heavy metals, pesticides, herbicides, leading significant contamination. This scenario requires implementation remediation strategies that both energy efficient. In this context, microbiological processes present a much promising approach mitigating pollution. Techniques bioremediation, which harness natural metabolic capabilities microorganisms, bioaugmentation, involves introduction specific strains increase degradation processes, being explored. These approaches vital restoring health, contributing conservation biodiversity, improving promoting long-term productivity.
