The anaerobic processes are superior to aerobic processes due to better dehalogenation of 2, 4, 6-Triclorphenol and easier control of releasing this toxic and odorous chemical compound into the air. However, anaerobic processes have lower reaction rates than aerobic processes. In this study, a rotating biological bed was used in an anaerobic sequencing batch reactor to increase the rate of anaerobic reactions. The anaerobic sequencing batch reactor equipped with a rotating biological bed removed more than 99% of the 2, 4, 6-Triclorphenol, 96% of total phenolic compounds, and more than 86% of its chemical oxidation demand in 2, 4, 6-Triclorphenol concentration of 430 mg/L and hydraulic retention time of 12 h. With the biological degradation of the 2, 4, 6-Triclorphenol by an anaerobic sequencing batch reactor Equipped with a rotating biological bed, more than 92% of the chlorine atoms in the structure of this compound were released into the effluent. Therefore, almost complete dehalogenation of 2, 4, 6-Triclorphenol is performed by this process. By removing the rotating biological bed from the anaerobic sequencing batch reactor equipped with a rotating biological bed, the bioreactor efficiency declined rapidly and progressed to failure. The role of rotating biological bed in dehalogenation (32%), biological degradation (10%), and mineralization (83%) of 2, 4, 6-Triclorphenol are very important. Therefore, a rotating biological bed has a significant role in promoting an anaerobic sequencing batch reactor. The anaerobic sequencing batch reactor equipped with a rotating biological bed can remove higher concentrations of 2, 4, 6-Triclorphenol at a lower hydraulic retention time than previously studied processes. Thus, the rotating biological bed can be an appropriate option for promoting anaerobic wastewater treatment plants that receive wastewater containing volatile, toxic, and complex organic compounds.Keywords: Anaerobic processbiological degradationrotating biological bed246-trichlorophenols Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThe authors gratefully acknowledge the financial and technical support of the Urmia University of Medical Sciences, Iran.","PeriodicalId":8935,"journal":{"name":"Bioremediation Journal","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135883183","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}

Isolates VK8 and VT7, screened from amongst 40 automobile service station soil isolates, showed promising growth in the presence of high thiocyanate concentration (500 mg/L). Biosurfactant BS1-S1W from isolate S1W (Brucella intermedia) enhanced the degradation of SCN− by Brachybacterium sp. (VT7) and Bacillus albus (VK8) by 92% and 95%, respectively, at 200 mg/L. Biosurfactant BS2-VO6 from isolate VO6-2 (Brevundimonas naejangsanensis) caused increment in the reduction of SCN- by 88% and 80%, respectively. FTIR and LC-MS analysis of the purified biosurfactants confirmed their glycolipid nature. Enhanced effect of biosurfactant was more pronounced at higher KSCN concentration. Little is known about the effects of microbial products on the enhancement of microbial biodegradation of SCN−. Production and application of biosurfactant from B. naejangsanensis has not been reported earlier and hence can lead to more effective biological agents of enhanced biomedical and environmental relevance.

Results of energy dispersive X-ray (EDX) and X-ray photoelectron spectroscopic (XPS) confirmed the chitosan coating and adsorption of Pb (II). Functional groups like -NH2, C-H and -OH groups were present on the ChCLP surface. The surface of ChCLP was observed to be rough and porous. Langmuir isotherm was best fitted in the adsorption data. This indicated toward the monolayer adsorption of Pb (II) onto the homogeneous surface of the adsorbent. The suitability of pseudo-second order (PSO) kinetic model indicated chemisorption of Pb (II) onto ChCLP. Thermodynamic study revealed endothermic and spontaneous Pb (II) adsorption. Values of the diffusion coefficient and dimensionless numbers indicated that Pb (II) adsorption was mix diffusion and transfer controlled. It was found that both the experimental and predicted values for ChCLP was close to each other showing a high R2 value in the range of 0.94 − 0.98. Results showed that ChCLP has high Pb (II) removal capacity (99.8%) at 100 mg/L and 10 g/L ChCLP dosage.

The goal of this study was to isolate yeasts capable of degrading carbamazepine. A hospital wastewater sample was used as an inoculant to carry out three successive transfers in minimal mineral medium added with 50 mg L−1 of carbamazepine. The isolates were characterized by colonial and microscopic morphology. A yeast was identified by sequencing its ITS1-5.8S-ITS2 intergenic region and by constructing of a phylogenetic tree. A kinetics of carbamazepine degradation was done with an initial concentration of 150 mg L−1 and the residual drug was determined by HPLC-UV. A total of 12 isolates were obtained, one of them had the characteristics of yeast (Carba14), the others were bacteria. Yeast isolate Carba 14 grew at all concentrations of carbamazepine tested (50, 100, 150 and 200 mg L−1) and grew better than bacterial isolates. This isolate degraded carbamazepine with an efficiency of 30% within 25 days. Yeast isolate Carba 14 was identified as Candida palmioleophila Carba 14.

Significantly higher yields of laccase and manganese peroxidase to the extent of 164.30 and 59.28 U/ml were registered in control containing only teak wood cubes than in the culture on combination of cubes and chlorpyrifos with 111.65 and 47.24 U/ml, respectively on 10th day of incubation. Reversed pattern in lignin peroxidase secretion with peak values on 6th day of incubation was noticed in the culture of S. ostrea immobilized on Tectona grandis cubes under influence of chlorpyrifos. Under free state conditions, significantly higher secretions of laccase (125.33 U/ml) and manganese peroxidase (53.60 U/ml) occurred in chlorpyrifos-amended medium than in the medium devoid of chlorpyrifos on 10th day incubation. Under moderate shaking conditions, supplementation of wheat bran alone at 3% level to the medium resulted in enhanced (3–5 folds) secretions of laccase, manganese peroxidase and lignin peroxidase by S. ostrea in medium free of wheat bran on 12th and 10th day of incubations. The presence of chlorpyrifos in addition to wheat bran in the medium further raised production of ligninolytic enzymes – laccase, MnP and LiP to the level of 311.78, 130 and 3 U/ml respectively on the 12th (higher LAC and MnP secretions) and 10th (higher LiP secretions) day of incubations. Our data in the present study suggest that secretion of ligninolytic enzymes by the culture is dependent on the nature of lignocellulosic material used in the study and secretion of higher titers of ligninolytic enzymes on cubes of Tectona grandis in the absence of chlorpyrifos rather in the presence of chlorpyrifos occurred. For executing microbial applications, it is critical to understand how lignocellulosic materials and toxic xenobiotic pesticides interact with white rot fungi and possible role of ligninolytic enzymes in the bioremediation process.","PeriodicalId":8935,"journal":{"name":"Bioremediation Journal","volume":"27 1","pages":"147 - 157"},"PeriodicalIF":2.0,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47709152","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}
