ClearBioremediation Performance of Marine Sponge Symbiont Bacteria against Nickel and Mercury Heavy Metal Pollutants
Researchers tested bacteria from marine sponges for their ability to remove heavy metal pollutants — specifically nickel and mercury — from water. The sponge-associated bacteria showed promising bioremediation activity, with removal efficiency varying by species and conditions. Marine symbiont bacteria could be developed as natural tools for cleaning up metal-contaminated water.
Effects of Dietary Gracilaria lichenoides and Bacillus amyloliquefaciens on Growth Performance, Antioxidant Capacity, and Intestinal Health of Penaeus monodon
Scientists tested whether adding the seaweed Gracilaria lichenoides and the beneficial bacterium Bacillus amyloliquefaciens to shrimp feed could improve growth and health in black tiger shrimp. Researchers found that the combination improved growth performance, boosted antioxidant defenses, and enhanced intestinal health compared to standard feed. The study suggests these natural dietary supplements could support healthier, more sustainable shrimp farming practices.
Over-Produced Extracellular Polymeric Substances and Activated Antioxidant Enzymes Attribute to Resistance of Pb(II) for Algal–Bacterial Granular Sludge in Municipal Wastewater Treatment
Researchers studied how lead contamination affects algal-bacterial granular sludge used in wastewater treatment. They found that while moderate lead concentrations were tolerable, higher levels disrupted the symbiotic relationship between algae and bacteria, reducing nitrogen and phosphorus removal performance. The study reveals that the sludge resists lead toxicity by overproducing extracellular polymeric substances and activating antioxidant enzymes.

Marine sponges as promising candidates for integrated aquaculture combining biomass increase and bioremediation: an updated review
This review examines the potential of marine sponges for integrated aquaculture, combining biomass production with bioremediation of polluted waters. Researchers found that sponge farming can filter particulate matter, bacteria, and contaminants from surrounding water, suggesting sponges may play a role in addressing marine pollution including microplastic particles.
From Waste to Resource: Algal–Bacterial Systems and Immobilization Techniques in Aquaculture Effluent Treatment
This review examines algal-bacterial symbiotic systems combined with microbial immobilization techniques as sustainable alternatives for treating aquaculture wastewater containing nitrogen, phosphorus, antibiotics, and heavy metals, with emphasis on simultaneous pollutant removal and biomass valorization.
Aquaculture Water Quality Improvement by Mixed Bacillus and Its Effects on Microbial Community Structure
This study tested two combinations of beneficial Bacillus bacteria in crucian carp aquaculture tanks, finding they improved water quality by reducing nitrogen and phosphorus compounds and shifted microbial community structure toward more beneficial species. Probiotic bacterial treatments offer a sustainable alternative to antibiotics for maintaining aquaculture water quality.
Individual and combined impact of microplastics and lead acetate on the freshwater shrimp (Caridina fossarum): Biochemical effects and physiological responses
Freshwater shrimp exposed to polyethylene microplastics combined with lead showed significantly worse toxic effects than when exposed to either pollutant alone, with microplastics increasing how much lead accumulated in the shrimp's tissues. This demonstrates that microplastics can act as carriers that amplify the toxicity of heavy metals in aquatic food chains, potentially increasing human exposure to dangerous metals through seafood.
Can Microplastics Influence the Accumulation of Pb in Tissues of Blue Crab?
This study assessed whether microplastics influence lead (Pb) accumulation in the tissues of blue crab, finding that microplastic co-exposure altered Pb uptake in some tissues, suggesting a potential vector effect that warrants further investigation.
Performance of Marine Sponge Symbiont Bacteria and Bacterial Isolates from Seawater in Pyrene Biodegradation
Researchers compared bacteria from marine sponge symbionts and open seawater for their ability to break down pyrene, a toxic polycyclic aromatic hydrocarbon. Marine sponge-associated bacteria showed strong pyrene degradation potential, suggesting their value for bioremediation of PAH-contaminated marine environments.
Resistance and removal mechanisms of deep-sea Bacillus sp. A260 in mitigating Mn2+ and microplastic pollution
Researchers isolated a manganese-resistant bacterium from deep-sea sediments that can simultaneously remove both manganese ions and microplastics from contaminated water. The bacterium achieved 97% manganese and 96% microplastic removal within 14 days by forming biofilms that adsorb the plastic particles. The study suggests this deep-sea organism could serve as a practical bioremediation tool for addressing combined metal and microplastic pollution.
Sea salt associated microplastics amplify pathogenic Vibrio and impair development in brine shrimp (Artemia franciscana)
Researchers found that microplastics present in harvested sea salt promoted biofilm formation by the pathogenic bacterium Vibrio harveyi and impaired the development of brine shrimp. The study suggests that microplastic contamination in sea salt could amplify pathogenic bacteria and increase infection risks in inland mariculture operations.
Biomineralization of Cd2+ and Pb2+ by sulfate-reducing bacteria Desulfovibrio desulfuricans and Desulfobulbus propionicus
Researchers used sulfate-reducing bacteria to immobilize cadmium and lead ions through biomineralization, finding that microplastics present in the system affected bacterial activity and metal precipitation efficiency, with implications for using biological approaches to treat heavy metal contamination in MP-polluted environments.
Polystyrene microplastics increase Pb bioaccumulation and health damage in the Chinese mitten crab Eriocheir sinensis
Researchers found that polystyrene microplastics significantly increased the accumulation of lead in the tissues of Chinese mitten crabs when both pollutants were present together. The combined exposure caused more severe oxidative stress, disrupted fat metabolism, and increased liver damage compared to lead exposure alone. The study suggests that microplastics can act as carriers for heavy metals in aquatic environments, amplifying their toxic effects on commercially important seafood species.
Co-Precipitation of CD, Cr, Pb, Zn, and Carbonates Using Vibrio harveyi Strain Isolated From Mediterranean Sea Sediment
Researchers isolated a Vibrio harveyi strain from Mediterranean Sea sediment and showed it can co-precipitate toxic heavy metals including cadmium, chromium, lead, and zinc with carbonates, offering a potential bioremediation strategy for metal-contaminated marine environments.
Early Detection of Heavy Metal Pollution with Biological Markers in Freshwater Clam (Corbicula javanica) in Maros River, Indonesia
Scientists found that freshwater clams can serve as early warning systems for dangerous heavy metals like lead and cadmium in rivers by producing special proteins called metallothioneins when exposed to these pollutants. The clams showed signs of metal poisoning within just one to five weeks, making them useful "canaries in the coal mine" for detecting water contamination before it reaches dangerous levels. This matters because heavy metals in water sources can eventually make their way into drinking water and food, potentially harming human health.
Synergistic effects of microplastic and lead trigger physiological and biochemical impairment in a mangrove crab
Researchers exposed mangrove fiddler crabs to microplastics and lead, both alone and in combination, to assess their joint toxic effects. They found that co-exposure synergistically increased lead bioaccumulation, oxygen consumption, and lipid peroxidation while suppressing antioxidant enzyme activity. The study suggests that microplastics can amplify the physiological harm of heavy metal contamination in sensitive mangrove ecosystems.
