Biochar, produced from organic waste, can improve soil quality in polluted areas. The present studies investigated the impact of biochar on cadmium uptake, biochemical and morpho-physiological parameters of <i>Ocimum basilicum</i> L. leaves under cadmium stress. A Pot study was conducted using a factorial experiment fitted into complete randomized design. This experimental design included three biochar treatments (control, 1%, and 2% of 2.5 kg soil) and three cadmium concentrations (0, 25, and 50 mg/kg soil), with five replications for each condition. This study's findings indicate that biochar application positively influenced morphological traits, relative water content, photosynthetic pigments, and catalase activity of <i>O. basilicum</i> plants subjected to cadmium stress. Additionally, application of biochar led to a reduction in total soluble sugars (23%), antioxidant activity (26%), total phenolic content, proline levels, soluble protein concentrations, electrolyte leakage, guaiacol peroxidase, and ascorbate peroxidase activities, as well as cadmium levels and target hazard quotient (THQ). Biochar use led to a reduction in THQ across all cadmium treatments. When the level of cadmium was at its highest (50 mg/kg), 2% biochar addition resulted in a 29.93% reduction in THQ compared to the treatment without biochar treatment. This study offers pragmatic options for amendment of contaminated soils, the augmentation of crop productivity, and the assurance of safe herb production. The integration of eco-friendly biochar technology with medicinal crop management connects agronomy, environmental science, and amendment, providing scalable options for sustainable agriculture.</p></div>","PeriodicalId":486,"journal":{"name":"Biodegradation","volume":"37 2","pages":""},"PeriodicalIF":3.2,"publicationDate":"2026-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147519637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was necessitated by the need to formulate an effective plan to make plants more tolerant to heavy metal-contaminated soil. The experiment was performed in a pot test using a completely randomized design with four replications. Nickel stress (100 mg/kg soil) significantly reduced root length (49.49%), shoot length (44.59%), root fresh weight (60.05%), shoot fresh weight (55.85%) and chlorophyll content (52.66%) compared to the unstressed control. The synergistic application of caffeic acid (1 mM), jasmonic acid (100 µM), salicylic acid (1 mM) and abscisic acid (50 µM) significantly mitigated these effects, increasing root length, shoot length by 21%1%, root fresh weight by 97%7% and shoot fresh weight by 59%9%, 21%1%, 97%7% and 45.31%, respectively, relative to the Ni-stressed control. This treatment also enhanced the activities of antioxidant enzymes, including superoxide dismutase (31.98%), peroxidase (46.24%), catalase (35.98%), ascorbate peroxidase (73.39%), glutathione peroxidase (62.94%) and glutathione reductase (64.76%), as well as non-enzymatic antioxidants such as ascorbic acid (48.57%), anthocyanins (64.40%), β-cyanin (27.83%), β-xanthin (42.13%), phenolic content (33.51%) and flavonoid content (38.70%). It also reduced Ni accumulation in roots, shoots and seeds by 33.72%, 36.31% and 49.69%, respectively, while improving the uptake of essential nutrients, such as Fe (30.66%), Mn (35.52%), Zn (32.98%) and N (14.99%). Photosynthetic efficiency, membrane stability and relative water content were also restored, leading to a 51.16% increase in seed yield. The synergistic interaction of these compounds enhances stress signaling, redox balance and metabolic regulation more effectively than their individual applications.

Reactors were operated using either a proteinaceous substrate (peptone) or a readily biodegradable substrate (acetate). Clear differences in the system's response were observed depending on the carbon source supplied. Peptone-fed systems sustained microbial activity and promoted effective BAC biodegradation, whereas acetate-fed systems exhibited pronounced toxicity, reduced biological activity, and negligible BAC removal. These contrasting behaviors were accompanied by marked shifts in microbial community diversity and composition. In parallel, exposure to BAC was associated to changes in antimicrobial susceptibility patterns, particularly affecting β-lactam antibiotics, that could be attributed to a substrate-dependent selective pressure. These results shows that carbon substrate composition may influence BAC biodegradation capacity and microbial adaptation in activated sludge systems. The findings contribute to a better understanding of the factors potentially controlling the biodegradation of quaternary ammonium compounds and highlight the important role of carbon availability in shaping microbial responses under BAC-associated selective stress.</p></div>","PeriodicalId":486,"journal":{"name":"Biodegradation","volume":"37 2","pages":""},"PeriodicalIF":3.2,"publicationDate":"2026-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147508493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mechanisms of Pb removal was determined based on equilibrium and kinetic models. Packed-bed biosorption studies using Pb solutions (750 mg L⁻¹ concentration) evaluated their efficacy for Pb uptake and removal, under the influence of initial pH of metal solution and the size of biosorbents. The reusability of the alginate-EPS beads was also tested by examining the column regeneration, exhaustion time and sorption–desorption activities of the Pb-loaded beads. Results revealed that the alginate-EPS beads produced have uneven surface with various functional groups (hydroxyl, amide, carboxyl, phosphates) detected. Their Pb removal efficacy was highest in Pb solutions with pH 4, recording 51.52% Pb removal, followed by pH 6 (48.62%) and pH 8 (46.78%). For bead size, alginate-EPS beads measuring 3 mm diameter size was more efficient in Pb removal (51.52%), compared to 2 mm- (39.23%) and 5 mm-sized beads (28.52%).
