The optimal conditions for biofilm production were determined, and the resulting structures were examined using a scanning electron microscope. A biofilm fertilizer was produced in a biofilm reactor. The microbial fertilizer maintained a viability of ∼10<sup>7</sup> CFU/mL for seven days across pH 4.5–8.5, 0.5%–6% NaCl, and 4°C–40°C. Greenhouse pot experiments with corn plants showed that <i>S. cerevisiae</i>-based biofilm fertilizers enhance soil phosphorus, potassium, and organic matter levels, thereby improving soil fertility and microbial activity. When applied in combination with reduced doses of chemical fertilizers, the biofilm formulation resulted in improvements in both soil microbial function and plant performance compared to the untreated control. A key innovation of this study lies in developing a multi-species biofilm system in which PGPR strains are associated with a pre-formed <i>S. cerevisiae</i> biofilm matrix, potentially enhancing consortium stability, synergistic interactions, and nutrient transformation under controlled conditions. These findings indicate that <i>S. cerevisiae</i>-based microbial biofilm fertilizers represent a promising, sustainable approach that could improve soil fertility, enhance beneficial microbial activity, and reduce reliance on chemical fertilizer inputs.</p>\u0000 </div>","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"54 6","pages":""},"PeriodicalIF":1.4,"publicationDate":"2026-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148174260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

To this end, we utilized the Intergovernmental Panel on Climate Change (IPCC)'s carbon accounting methodology and Tapio decoupling model to quantify and evaluate the dynamics and decoupling relationship of carbon emissions within the Yellow River Basin of Henan Province (HYRB) spanning from 2010 to 2019. Key findings reveal: (1) HYRB's carbon emissions exhibited an initial rise followed by a subsequent decline from 2010 to 2019, peaking in 2013 at 13 837.5 × 10<sup>4</sup> t. Sectorally, energy consumption dominated (73.9%), followed by cement production (17.6%, peaking at 2683.3 × 10<sup>4</sup> t in 2014) and agricultural activities (8.5%). (2) Carbon intensity decreased by 50.4% with significant spatial heterogeneity. The Zhengzhou–Luoyang–Xinxiang urban cluster formed a high-value agglomeration core (contributing 60.7%), resource-based cities (e.g., Jiaozuo, Sanmenxia) exhibited prominent energy dependence, while Kaifeng and Puyang showed agricultural-dominated emissions. (3) HYRB achieved a weak decoupling trend with the decoupling index for 2014–2019 (0.04) outperforming that for 2010–2014 (0.27), with distinct regional pathways. Five cities shifted to strong decoupling, while Puyang degraded to growth–connection (0.94) due to energy rebound effects. The study proposes differentiated strategies: core regions should enhance industrial–transport synergy, resource-based cities accelerate energy substitution, and agricultural areas adopt low-carbon technologies.

Additionally, the pseudo-first-order kinetic model indicated that physical adsorption predominated on the surface of the biochars. The unique properties of the biochars, such as their porous structure, diverse surface functional groups, and high concentration of base cations, played a critical role in the effective adsorption of Cd(II).

Prior reviews largely treat renewable deployment, energy access, energy governance, and just-transition governance as separate domains, leaving a limited SDG 7–aligned synthesis that integrates mine-land repurposing potential with the institutional, financial, and equity constraints that shape outcomes in India's coal belt. To address this gap, this study provides a coal-region-specific, SDG 7–benchmarked evidence synthesis linking energy access within a unified just-transition framework. A systematic narrative review was conducted following PRISMA 2020 guidance, screening 68 studies (2020–2025) alongside relevant policy datasets. Findings highlight major opportunities, including solar deployment on reclaimed mine lands (27.11 GW), pumped hydro storage (∼183 GW), biomass co-firing, and mine methane recovery (54%), supported by financing instruments, such as the District Mineral Foundation (DMF). However, the binding constraints are predominantly institutional rather than technological—fragmented planning, regulatory and land-related frictions, investment “bankability” gaps, limited workforce readiness, and weak community benefit-sharing. On the basis of the synthesized evidence, the study advances a prioritized pathway for coal regions: scale mine-land renewables and storage, mainstream methane utilization and efficiency measures, reorient DMF/CSR flows toward equity-centered transition investments, and embed reliability-adjusted SDG 7 indicators within coordinated national–state roadmaps to deliver measurable, socially inclusive, and durable energy transition outcomes.</p>\u0000 </div>","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"54 6","pages":""},"PeriodicalIF":1.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148173853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Larvae of the greater wax moth (<i>Galleria mellonella</i> Linnaeus) can feed on polymers, although the microbiological mechanism behind this observation is not well understood. Larvae were cultured on an artificial diet with various polymers (high-density polyethylene [HDPE], low-density polyethylene [LDPE], polystyrene [PS], and polyvinyl chloride [PVC]), and their gut bacteria were profiled by 16S ribosomal RNA gene (V1–V9) sequencing on the Oxford Nanopore platform. Bioinformatics pipelines were used to analyze diversity, taxonomic composition, and predicted metabolic functions. Sequencing revealed that the bacterial community in the gut was dominated by the phylum Bacillota, with <i>Mammaliicoccus sciuri</i> accounting for more than 90% of the total reads across all diets. Despite this dominance, plastic-incorporated diets promoted low-abundance taxa, increasing richness while maintaining similar evenness compared to the control. Beta diversity revealed distinct clustering of plastic-fed samples, indicating polymer-specific microbial shifts. Functional predictions showed enrichment of pathways related to heterotrophic metabolism, hydrocarbon degradation, fatty acid oxidation, and stress response, particularly in the HDPE- and PVC-fed groups. These results indicate that plastic-incorporated diets drive compositional and functional restructuring of the gut microbiota, suggesting microbial adaptation toward hydrocarbon utilization that may underpin early-stage plastic biodegradation. However, these findings are based on predictive functional analyses and should be considered as presumptive evidence of potential plastic biodegradation, requiring further experimental validation through physicochemical and enzymatic studies.</p>\u0000 </div>","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"54 6","pages":""},"PeriodicalIF":1.4,"publicationDate":"2026-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148098039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
