This study examines the bioremediation potential of three indigenous bacterial strains Aeromonas caviae KQ_21, Aeromonas hydrophila AUoR_24, and Shewanella putrefaciens SUoR_24 evaluated both individually and in consortia for their capacity to remove heavy metals. Tolerance assessments demonstrated that the coculture of these strains exhibited superior resistance to copper (Cu), zinc (Zn), and nickel (Ni), with optimal growth observed up to 6 mM for Cu, 9 mM for Zn, and 5 mM for Ni, outperforming the monocultures. The co-culture system also achieved higher metal reduction efficiencies, with reductions of 47.02% for Cu, 61.49% for Ni, and 61.93% for Zn, in contrast to lower reductions observed in individual strains. The study further explored the impact of environmental conditions on bioremediation efficiency. Optimal temperature for both monoculture and coculture setups was found to be 30 °C. pH and salt concentration variations significantly affected bacterial growth and metal reduction, highlighting the necessity of tailored conditions for enhanced bioremediation. In terms of metal removal mechanisms, the results demonstrated that nickel (Ni) removal occurred primarily through bioaccumulation, while copper (Cu) removal involved both biosorption and bioaccumulation. Zinc (Zn) removal was facilitated through biosorption, bioaccumulation, and biotransformation. These findings underscore the effectiveness of bacterial consortia, particularly indigenous strains, in improving heavy metal tolerance and reduction through synergistic interactions and cooperative metabolic processes. This research offers valuable insights into optimizing bacterial consortia for environmental cleanup and advances the application of indigenous bacteria in bioremediation strategies. Future investigations should focus on exploring additional microbial species and further elucidating the molecular mechanisms that contribute to enhanced bioremediation efficacy.</p>","PeriodicalId":11759,"journal":{"name":"Environmental Geochemistry and Health","volume":"47 3","pages":"79"},"PeriodicalIF":3.2,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143448585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the spatial distribution and origins of heavy metals within this zone is crucial for studying riverine ecosystems. In this research, we assessed the occurrence forms and spatial patterns of heavy metals in the riparian zone of the Shaying River Basin in Zhoukou City. Environmental risks were preliminarily evaluated using indices such as I_geo, RI, and PLI, and the sources of heavy metals were identified through PMF. The results revealed that the overall ecological risk associated with eight analyzed heavy metals (Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn) in this region was low. However, Cd is marked enriched and represents a significant factor contributing to the potential ecological risk within the riparian zone of the basin. The high bioavailability of Cd and Mn in the soils of nine more contaminated sites showed moderate to very high ecological risk. The PMF model identified four pollution primary sources in this region: agricultural and industrial activities (29.4%), upstream water pollution (21.1%), natural sources (26.5%), and transport-related source (23.1%).

An Oxisol sample was contaminated in the laboratory using a dosage of 6.5% fluorescent lamp powder relative to the mass of soil. The mobility of metals was assessed through a sequential extraction protocol of the Community Bureau of Reference. To assess potential risks, a mathematical model of Human Health Risk Assessment was employed, based on human exposure on metal-contaminated groundwater from soil contamination. Evaluation of metal mobility showed that 6% of Ni and 30% of Cu in contaminated soil were in the potentially bioavailable fraction. The slightly acidic pH of the contaminated soil seems to influence the mobility of Ni and Cu. Zn and Pb were mainly found in the residual fraction, suggesting low geochemical availability. However, over time, metals may be leached, highlighting the importance of monitoring disposal areas. When these results are compared to the mobility profile found in extractions applied to pure fluorescent lamps waste, the data suggest that soil properties tend to reduce metal mobility.

Once in the food chain, HMs can cause mild to life-threatening side effects thereby negatively affecting the environment and human health. To remedy this situation, cost-effective and environmentally friendly remediation approaches are needed to ensure food safety. Phytoremediation is a remediation technique that meets these criteria; however, it is still unclear whether co-cultivation of food crops during phytoremediation can produce crops that meet the required safety standards. In this study, we investigate the effectiveness of phytoremediation and food crop co-cultivation to produce \"HM-free\" crops from farmland soils in Sidi village in Xingping Town of Guangxi Zhuang Autonomous Region in China, contaminated by HMs from a lead-zinc mine. Our results show that (1) After 19 months of phytoremediation, the redistribution of HMs (cadmium, lead, and arsenic) from acidic to slightly acidic, neutral, and mostly weakly alkaline soils was promoted. This resulted in a reduction in HMs availability and consequently the amount absorbed by food crops. (2) The concentrations of important nutrients including nitrogen, phosphorus, and potassium were significantly increased during phytoremediation. This translated to increased plant biomass in Celosia Argentea L. (26.09%), Sedum erythrostictum Migo (18.52%), and Amaranthus cruentus L. (21.67, 33.33, and 66.67%, for consecutive harvests). (3) Co-cultivation of maize crops with low HM accumulator plants in slightly and moderately polluted sites or a rotation of rapeseed-sunflower plants with hyperaccumulator plants in the highly polluted site ensured 100% compliance with the food crop and feed safety standards.
