Abstract Wastewater treatment poses a significant challenge to sustaining intensive aquaculture systems, as these systems generate substantial waste including nitrogen compounds (ammonia, nitrite and nitrates), total solids, phosphorus. The accumulation of products negatively impacts the fish production. Consequently, various wastewater methods (physical, chemical biological methods) have been implemented in aquaculture. Among, (bioremediation) are more efficient environmentally sustainable compared other methods. This review provides an overview latest technological options for use bacteria, microalgae, bacteria-algae symbiosis. These microorganisms based remediation activities represented constructed wetlands, ecological floating beds, recirculating system (RAS), biofloc system, aquaponics Integrated multitrophic (IMTA). It also explores potential integration among production on integrated microorganism’s roles water treatment, increasing sustainability practices.

Nitrate is the most prevalent inorganic pollutant in aquatic environments, posing a significant threat to human health and ecological environment, especially lakes groundwater, which are located high agricultural activity intensity areas. In order reveal sources of nitrogen pollution this study transformation mechanism interaction zone between groundwater has become an important foundation for prevention control. The coupling effect biogeochemical processes nitrate iron been pointed out be widely present various water environments recent years. However, impact minerals on reduction lake–groundwater high-salinity environment still remains uncertain. Based sediment chemistry characteristics Chagan Lake–groundwater northeastern China (groundwater TDS: 420~530 mg/L, Na+: 180~200 Cl−: 15~20 mg/L lake 470~500 210~240 71.40~87.09 mg/L), simulated relative oxidizing open system conditions reducing closed investigate hematite siderite effects microbial behavior. results indicated that both promoted system, whereas only system.

Linear anionic surfactants (LAS) pose significant stress to microbial denitrification in wastewater treatment. This study investigated the performance and adaptation mechanisms of heterotrophic nitrification-aerobic (HN-AD) consortia under LAS exposure after short-term (SCM, 2 months) long-term (LCM, 6 acclimation. Results showed a dose-dependent inhibition total nitrogen (TN) removal, with LCM achieving 97.40% TN removal 300 mg/L LAS, which was 16.89% higher than SCM. Biochemical assays indicated that exhibited lower reactive oxygen species (ROS) levels, ATP content, reduced LDH release, suggesting enhanced oxidative resistance membrane stability. EPS secretion also increased LCM, contributing environmental tolerance. Metagenomic analysis revealed acclimation enriched key genera including Pseudomonas, Aeromonas, Stutzerimonas, maintained expression (e.g., nosZ, nirS) ammonium assimilation genes (glnA, gltB). Although high concentrations overall community diversity led convergence between SCM structures, retained greater functional capacity resistance. These findings underscore importance sustaining surfactant pressure offer valuable insights for engineering robust complex environments.
