Although phosphate-solubilizing bacteria (PSB) can convert insoluble P into bioavailable forms, their application is limited by poor colonization and stress tolerance. In this study, a biochar-microbe composite (PSB1@PBC) was prepared by immobilizing PSB <em>Raoultella ornithinolytica</em> (PSB1) on P-enriched sludge biochar (PBC) to enhance P transformation and release. PSB1@PBC improved P release and bacterial survival, with cell density 1.51 times that of free-living cells. Hedley sequential extraction showed a decrease in stable HCl-P from 13.20% to 8.90%, whereas bioavailable NaHCO<sub>3</sub>-P increased by 1.96%. P release followed a biphasic pattern, characterized by an initial rapid phase (0–4 days) followed by a slow and stable phase, peaking at 26.80 mg/g (17.5 times that of unmodified PBC) after 4 days. This improvement is attributed to three synergistic mechanisms: (i) microbial acidification <em>via</em> malonic acid secretion, which promotes mineral-bound P dissolution; (ii) enzymatic mineralization, which increases phosphatase activity to hydrolyze organic P; and (iii) chelation-assisted dissolution through siderophore production. The release of P shifted from slow chemical dissolution in PBC to rapid microbial solubilization in PSB1@PBC, with biochar transport becoming the rate-limiting step. This study demonstrated a sustainable strategy for P recovery, highlighting the potential of PSB1@PBC to enhance nutrient cycling and agricultural sustainability.</div></div>","PeriodicalId":100595,"journal":{"name":"Green Carbon","volume":"4 2","pages":"Pages 158-168"},"PeriodicalIF":14.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148573262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of metal-organic frameworks (MOFs) and their subgroup, zeolitic imidazolate frameworks (ZIFs), have emerged as prominent materials in CO<sub>2</sub> capture research. Among these, the most widely studied and utilized ZIF is the zinc 2-methylimidazolate with sodalite topology known as ZIF–8. Despite its exceptionally high porosity and stability under hydrothermal and chemical conditions, ZIF–8 has shown limited utility as a CO<sub>2</sub> adsorbent due to its low uptake capacity. This limitation is primarily attributed to the absence of polar functional groups in the framework, reducing interactions between the framework and CO<sub>2</sub>. With the growing interest in mechanochemistry for the synthesis of reticular materials, we explored the incorporation of linkers with polar groups using mechanical forces. Initially, we focused on a system based on ZIF–8 and imidazole-2-carboxaldehyde as polar exchange linker. The optimal conditions, which achieved linker exchange of up to 63% within 15 min, were subsequently tested with four additional imidazole linkers with 4-carbaldehyde, hydroxide, and chloride functional groups.
