In this study, the ability of selected bacterial strains to degrade crude oil and its components was evaluated through growth experiments and gas chromatographic analysis. The strains were taxonomically characterized as Alcanivorax, Labrenzia, Halomonas, Acinetobacter, Alcaligenes, Pseudomonas and Brevundimonas. Four different bacterial consortia were constructed and their biodegradation capabilities were evaluated. One of them showing high degradation capability of aliphatic and polycyclic aromatic hydrocarbons has been used for bioaugmentation in a microcosm for 30 days, and its bioremediation potential showed significant reduction of hydrocarbons in contaminated sediments.Keywords: Hydrocarbons degrading bacteriabiodegradationmicrobial consortiaallochthonous bioaugmentationbioremediationDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).

Various processes are currently investigated to eliminate such anthropogenic micropollutants, among them advanced oxidation processes, where hydroxyl radicals cause disintegration of many organic substances. For mechanistic understanding and optimization for potential in-field use, kinetic descriptions and chemical reaction knowledge are important. Structural identification, quantitation and kinetic description of the substances are investigated via a univariate method, i.e. high-performance liquid-chromatography coupled with mass spectrometry and curve-fitting, and a multivariate method, i.e. absorption spectroscopy and curve resolution-alternating least squares fitting. The latter represented a fast, non-laborious analytical method. The univariate approach revealed four known and two new transformation products. First-order kinetics with follow-up reactions were observed. The univariate method yielded rate constants of about 0.33 min−1 for the degradation of both tetracyclines and distinct rate constants for transformation products, while rate constants of about 0.22 and 0.27 min−1 and an overall rate constant for non-identified transformation products were obtained from multivariate analysis due to the insufficient discriminatory power. Structural characterization, fast and easy kinetic parameter determination of photoinduced degradation may contribute to optimize advanced oxidation processes for the removal of antibiotics from waste water.Keywords: MCR-ALStetracyclineoxytetracyclineAOPskinetic determinationHPLC-HRMSDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).

Ag2O nanoparticles were uniformly distributed on the surface of g-C3N4 and a heterostructure was formed. The sample Ag2O@g-C3N4 degraded methylene blue (MB) dye by visible light, which showed that it had good photocatalytic activity. Under the same catalytic conditions, the catalytic efficiency of Ag2O@g-C3N4 is two times higher than that of pure g-C3N4. The improvement in catalytic efficiency is due to the formation of heterostructure between Ag2O and g-C3N4, which greatly reduces the recombination rate of electrons and holes. At the same time, Ag is a good electron trapping agent, which increases the mobility of electrons and holes and inhibits the photoetching of Ag2O. Finally, the photocatalytic principle of Ag2O@ g-C3N4 was analyzed for its excellent photocatalytic performance.","PeriodicalId":23210,"journal":{"name":"Toxicological & Environmental Chemistry","volume":"56 1","pages":"60 - 74"},"PeriodicalIF":0.0,"publicationDate":"2023-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82889208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Organophosphates simultaneously are both dangerous and useful substances. Dangerous since they are employed in chemical warfare and useful when they are applied as pesticides. Here, we suggest the models for organophosphates binding to AChE k1 developed via representing the molecular structure by a simplified molecular input-line entry system using so-called optimal descriptors calculated with the Monte Carlo technique using the Correlation and Logic (CORAL) free software available on the Internet (http://www.insilico.eu/coral). Quantitative structure-activity relationships (QSARs) serve to develop predictive models for organophosphates. The predictive potential of these models is quite good: the determination coefficient for the validation set ranged from 0.87 to 0.90. These models were built up according to the principle ‘QSARs is a random event’, that is, predictive potential of an approach should be checked up with several splits of available data into the training and test sets. The special scheme of mechanistic interpretation definition is represented. The mechanistic interpretation is based on probabilities of molecular features to be in the sub-group of promoters of increase for endpoint or in sub-group of promoters of it is decrease.","PeriodicalId":23210,"journal":{"name":"Toxicological & Environmental Chemistry","volume":"36 1","pages":"19 - 27"},"PeriodicalIF":0.0,"publicationDate":"2023-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86765724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
