Plant growth, root morphology, root exudates, microbial population, dehydrogenase activity, residual TPH concentration, and LDPE MP degradation were evaluated. M. luteus significantly increased plant biomass and improved TPH degradation by 79.16% and 64.43%, which were 25.04% and 15.85% higher than uninoculated treatments. M. luteus inoculation still led to higher TPH removal compared to uninoculated treatments despite MP-induced alterations in plant biochemical and morphological traits. GC/MS analysis of lemongrass root exudates showed that M. luteus enriched plants with GABA-associated allelochemicals. FTIR analysis indicated accelerated oxidation of LDPE MPs in planted treatments compared to unplanted ones, evidenced by increased absorbance at characteristic peaks (3620.71 cm-1 O-H stretching, 1651 cm-1 C=O stretching, and 1031.10 cm-1 C-O stretching). This strongly suggests a co-metabolic breakdown of LDPE MPs within the plant rhizosphere (a degradation hotspot). Lemongrass essential oil was not significantly affected by the contaminant or M. luteus. This study highlights the lemongrass-M. luteus association as a promising candidate for the remediation of both petroleum- and MP-contaminated soil, with the added benefit of essential oil production.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"1-14"},"PeriodicalIF":3.1,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145199347","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}

The highest plant height (34.0 cm) and biomass (30.0 g) occurred with 2% biochar, compared to 16.0 cm and 9.0 g in control.

For Cd, both max BCF (3.40) and TF (1.4) were seen at 1% biochar. Metal uptake and transfer significantly correlated with biomass and soil factors such as fertility (N, P, and K), pH, sodium adsorption ratio (SAR), and organic matter (OM) (Mantel test: p = 0.1, r = 0.4). The Group Method of Data Handling (GMDH) model, with high accuracy (R2 = 0.998), showed compost caused an initial rise then decline in Cd uptake, while biochar had the opposite effect.

Our comprehensive evaluation revealed that strain B16 exhibits multiple beneficial traits such as phosphate solubilization, nitrogen fixation, siderophore production, and the synthesis of indole-3-acetic acid (IAA), which are pivotal for enhancing plant growth. The results from pot experiments show that B16 significantly improves growth parameters in mustard, green gram, and bengal gram, confirming its potential to contribute to eco-friendly agricultural practices. The strain's robustness in salt stress conditions and its ability to form biofilms further affirm its potential as a biofertilizer.
