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%.</p>\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}

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.

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.
