Pseudomonas aeruginosa JU_CHE_01 (OR388872) was the isolated strain, as determined by phylogenetic analysis. P. aeruginosa JU_CHE_01 shown the ability to break down 600 mg/L concentration of RR120 dye along with many harmful textile azo dyes. The strain also showed resistance to ampicillin and cefradine but remained susceptible to other tested antibiotics. Five process factors were evaluated for optimal condition using the Taguchi approach. Three physicochemical parameters (pH, temperature, and inoculum dose) and two media components (glucose and yeast extract) were optimized because of their significant impact on RR120 biodegradation. The L-18 orthogonal arrays (OAs) architecture was utilized in the design of multiple experimental studies. Analysis of the experimental data was done using the signal-to-noise (S/N) ratio with the “larger is better” features to determine the key variables and ideal circumstances for optimizing RR120 dye biodegradation. When the predicted data was validated using the confirmatory experiments, it was found that under the ideal conditions of glucose and yeast extract of concentration 1 g/L each, pH 8, temperature 37°C, and inoculum dose 10% (v/v) in 48 h, 97.63% of the RR120 dye degradation could be achieved, leading to a 66.75% enhancement in the RR120 degradation. Analysis of variance (ANOVA) indicated that the nitrogen source (yeast extract) and carbon source (glucose) significantly influenced RR120 biodegradation, accounting for 27.933% and 19.526%, respectively, followed by pH at 4.664%, temperature at 13.476%, and inoculum dose at 28.951%.\u0000 </div>","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"53 7","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144550842","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 saffron stamen was utilized to obtain sporopollenin, which was then magnetized employing Fe3O4 followed by GO to produce a sorbent of the Fe3O4-SSSP/GO type. The result indicates that the Fe3O4-SSSP/GO is a suitable sorbent for solid-phase extraction of four PAHs: benzo[a]anthracene (BaA), chrysene (Chr), benzo[b]fluoranthene (BbF), and benzo[a]pyrene (BaP), found in tea and saffron samples. Scanning electron microscopy and Fourier-transform infrared spectroscopy were used to characterize the sorbent. Taguchi analysis was employed to optimize the main parameters for extraction, such as sample volume, sorbent amount, desorption volume, and pH of the investigated PAHs. The calibration curve for determining BaA, Chr, BbF, and BaP was investigated in the 0.5 to 500 ng mL−1 range. The limit of detection (LOD, S/N = 3) and limit of quantification (LOQ, S/N = 10) were between 0.03 and 0.14 ng mL−1.

In this study, 385 topsoil samples (0–20 cm) and 118 deep soil samples (150–200 cm) were collected from Nanyang City to investigate the spatial distribution, contamination, and source allocation of TMs. Geographic information system analysis, contamination factor (CF), geo-accumulation index (Igeo), and positive matrix factorization (PMF) model were utilized. The results showed that the mean contents of Cu, Hg, Pb, and Zn in the study area's topsoil (25.50, 0.035, 28.51, and 79.46 mg kg−1) exceeded background values. CF and Igeo results indicated that over 60% of soil samples were contaminated by Hg, the main contaminant in soil. By combining correlation and PMF analysis, three sources of TMs were identified for (a) Pb (75.4%), Hg (63.7%), and Zn (55.6%), primarily associated with industrial emissions and atmospheric deposition; (b) Co (57.5%), Cr (50.8%), Cu (59.2%), and Ni (46.4%) mainly originated from natural sources; and (c) As (72.8%) primarily from agricultural activities. The proportions of the three sources were 36.27%, 39.76%, and 23.97%, respectively. Anthropogenic sources contributed the most to soil TMs (60.24%), higher than natural sources, indicating substantial accumulation of TMs in topsoil due to significant anthropogenic activities.

We collected samples from a garden in Iran where DZ has been used for a long time. This allowed us to extract three types of bacteria capable of degrading DZ. Through biochemical and molecular tests, these bacteria were identified as Pseudomonas oryzihabitans, Enterobacter kobei, and Serratia species. The bacteria were cultured for 10 days in broth and soil media with DZ concentrations of 10 and 20 ppm. The degradation and utilization of the toxin by the bacteria were measured using gas chromatography. The results indicated that P. oryzihabitans degraded the toxin at concentrations of 10 and 20 ppm in liquid medium by 47.1% and 27.45%, respectively. In soil medium, the bacteria degraded 96.5% and 97.1% of the toxin at the same concentrations. Serratia sp. degraded DZ in broth medium with initial concentrations of 10 and 20 ppm by 64.3% and 78.4%, respectively. Additionally, these bacteria were able to degrade DZ by 90.2% and 98.25% in soil. E. kobei consumed DZ in the broth and soil media at rates of 23.1% and 17.95% and 31.19% and 88.05%, respectively. According to the results, P. oryzihabitans exhibited the highest degradation capacity compared to the other bacteria.

However, the prior research on the nexus between TUN and the environmental quality (ENQ) records contradictory results, which may be inconvenient when recommending environmental protection policies. The goal of this research was to look into the asymmetric link between TUN and ENQ in the selected newly industrialized economies. Previous studies utilized panel data methods, yielding similar conclusions about the linkage between TUN and ENQ, regardless of the truth that many economies did not develop such interconnectednhess individually. On the other hand, the current work employs a distinctive methodology, “quantile-on-quantile,” that allows researchers to analyze time-series dependency in every nation by providing universal yet economy-specific details on the association between the variables. As per estimates, TUN boosts ENQ in majority of our selected nations.
