By evaluating two mass ratios (1:1 and 1:2) of PHBV to pyrite in lab-scale permeable reactive barrier systems, the research reveals high nitrate removal efficiencies of up to 97.65%, with minimal dissolved organic carbon in the effluent. Microbial analysis indicates that pyrite content significantly influences microbial community structure and functional gene expression, with the 1:2 ratio favoring aerobic denitrifiers and a broader functional gene profile. The findings highlight a promising, cost-effective mixtrophic denitrification strategy for sustainable groundwater remediation.","brand":"Eliva Press","offers":[{"title":"Default Title","offer_id":53794460139862,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/5829\/5382\/files\/product_image_9789999326971_1.jpg?v=1781806555","url":"https:\/\/www.momoxbooks.com\/products\/qian-zhengkun-pyrite-and-phbv-combined-as-substrates-for-groundwater-denitrification-9789999326971","provider":"momoxbooks","version":"1.0","type":"link"}
