Toxic Microcystis blooms are widespread in aquatic bodies, posing major threats to and human life. Recently, bioflocculants have attracted considerable attention as a promising biomaterial for management. In search of novel organism that can produce an efficient bioflocculant controlling harmful algae sustainably, the native gastropod Cipangopaludina chinensis was co-cultured continuously with toxic under different initial algal cell densities. The bioflocculation effect snail mucus on Microcystis, microcystin removal, toxin accumulation snails investigated. addition, properties adhesive were characterized using microscopic, X-ray diffraction, infrared spectroscopy, polysaccharide proteome analyses. cells captured flocculated by mucus; removal efficiencies up 89.9% 84.8% achieved microalgae microcystin-leucine arginine (MC-LR), respectively, when C. only one day. After nine-day exposure, less than 5.49 µg/kg DW microcystins accumulated snails, indicating safety consumption. contained 104.3 µg/mg protein 72.7 carbohydrate, which provide several functional groups beneficial bioflocculation. main monosaccharide subunits polysaccharides galactose, galactosamine, glucosamine, fucose, glucose, mannose. Most them key components many bioflocculants. Gene Ontology analysis indicated enrichment binding processes catalytic activity, may account via or enzymatic reactions. findings indicate secretes act from ambient water be effective eco-friendly tool suppression.

Biological treatment is currently a favorable option to treat wastewater due its environmentally friendly methods and minimal toxic by-products. The majority of biological uses bacteria as agents, which are known have excellent capabilities for removing various pollutants. Researchers extensively explored the use extracellular polymeric substances (EPSs) generated by in treatment. This review focuses on sources EPSs, factors influencing their production, role Bacterial species, nutrient availability, pH, temperatures, presence toxins were mentioned be EPS production Produced EPSs may promote aggregation, adsorption, decolorization, degradation highlights challenges discovering new potential bacterial species complex extraction methods, well importance mass larger-scale applications.

Aquaculture sector plays important role for the economic development in Malaysia, but environmental concerns are arising due to pollution caused by discharge of untreated wastewater.Coagulation-flocculation-sedimentation is currently best practice aquaculture wastewater treatment.This research aims compare performance chemical-based (alum) and bio-based (neem leaves) coagulants treating effluent while also studying feasibility.Alum showed higher removal efficiencies total suspended solid (99.7%), turbidity (98.8%), color (97.3%), neem coagulant a lower dosage needed achieve optimum performance.The cost included capital operational costs, benefit potential water reuse reclaimed valuable products from sludge.The net profit reveals negative values both scenarios, cost-benefit ratio 0 0.06 alum coagulants, respectively.These indicated that scenarios not feasible gain economical profit, utilization present sludge utilization.A deeper analysis using Social Return on Investment (SROI) method suggested include non-traditional calculation such as social scenarios.
