| 1 | Investigation on removal pathways of Di 2-ethyl hexyl phthalate from synthetic municipal wastewater using a submerged membrane bioreactor显示文摘Highly hydrophobic Di 2-ethyl hexyl phthalate(DEHP) is one of the most prevalent plasticizers in wastewaters. Since its half-life in biological treatment is around 25 days, it can be used as an efficiency indicator of wastewater treatment plant for the removal of hydrophobic emerging contaminants. In this study, the performance of submerged membrane bioreactor was monitored to understand the effect of DEHP on the growth of aerobic microorganisms. The data showed that the chemical oxygen demand(COD)and ammonia concentration were detected below 10 and 1.0 mg/L, respectively for operating conditions of hydraulic retention time(HRT) = 4 and 6 hr, sludge retention time(SRT) = 140 day and sludge concentration between 11.5 and 15.8 g volatile solid(VS)/L. The removal efficiency of DEHP under these conditions was higher and ranged between 91% and 98%. Results also showed that the removal efficiency of DEHP in biological treatment depended on the concentration of sludge, as adsorption is the main mechanism of its removal. For the submerged membrane bioreactor, the pore size is the pivotal factor for DEHP removal, since it determines the amount of soluble microbial products coming out of the process. Highly assimilated microorganisms increase the biodegradation rate, as 74% of inlet DEHP was biodegraded; however, the concentration of DEHP inside sludge was beyond the discharge limit. Understanding the fate of DEHP in membrane bioreactor,which is one of the most promising and futuristic treatment process could provide replacement for conventional processes to satisfy the future stricter regulations on emerging contaminants. | Mehdi Zolfaghari Patrick Drogui Brahima Seyhi Satinder Kaur Brar Gerardo Buelna Rino Dubé Nouha Klai | 2015 | Journal of Environmental Sciences2015，27，11： | 2 |

| 14 | Biodiesel production from microbial lipid obtained by intermittent feeding of municipal sludge and treated crude glycerol显示文摘In the present study,municipal secondary sludge and purified glycerol(obtained after acid treatment of crude glycerol)were used together for lipid production using intermittent feeding strategy.Intermittent sludge feeding strategy(sludge SS 30 g/L)resulted in a higher biomass(54.99 g/L)and lipid concentration(25.35 g/L)at 96 h when compared to 35 g/L SS single sludge feeding or control strategy(45.67 g/L biomass&19.16 g/L lipid).Moreover,the intermittent sludge feeding strategy significantly reduced foaming and requirement of anti-foam during fermentation when compared to control strategy.The energy balance of biodiesel production from lipid obtained by intermittent sludge feeding strategy(30 g/L SS)was energeti-cally favorable.It was also revealed from yield coefficients and energy balance that sludge had an important contribution in microbial lipid and biodiesel production. | Lalit R.Kumar Sravan K.Yellapu R.D.Tyagi Patrick Drogui | 2021 | Systems Microbiology and Biomanufacturing2021，1，3： | 0 |
| 15 | Optimization of trace elements in purified glycerol for microbial lipid and citric acid production by Yarrowia lipolytica SKY7显示文摘Purified glycerol obtained after acid treatment of crude glycerol solution was used as the carbon source for lipid and citric acid production using Y.lipolytica SKY7.Although purified glycerol was high in phosphorus,it was important to inves-tigate the impact of fortification of trace elements in the medium on cell growth,lipid and citric acid(CA)production.When all the trace elements(including phosphates and sulfates)required for growth and lipid production were added to the purified glycerol medium,high biomass(51.67 g/L)and lipid concentration(19.47 g/L)were observed at 96 h of fed-batch fermentation with low CA concentration of 5.42 g/L.The purified glycerol medium without additional trace elements gave low biomass(27.67 g/L),lipid concentration(9.35 g/L)at 80 h of fed-batch fermentation,but gave high CA concentration(24.51 g/L).When purified glycerol was provided with only sulfates or all elements except KH_(2)PO_(4),low biomass(32.59 g/L and 38.52 g/L)and citric acid concentration(1 g/L and 2.42 g/L)were obtained at 96 h. | Lalit R.Kumar Sravan K.Yellapu R.D.Tyagi Patrick Drogui | 2021 | Systems Microbiology and Biomanufacturing2021，1，1： | 0 |
| 16 | ORIGINAL ARTICLE Dynamics of bacterial community at varying sludge retention time within membrane bioreactor treating synthetic hospital wastewater显示文摘The study was conducted to investigate the effect of sludge retention on bacterial community composition of membrane bioreactor(MBR)treating synthetic hospital wastewater.The removal of four pharmaceuticals,namely carbamazepine,estradiol,venlafaxine,and ibuprofen in MBR,was studied at varying sludge retention time(SRT)duration of 100,45,and 15 days and hydraulic retention time(HRT)of 18 h.The removal of ibuprofen and estradiol was constant at varying SRT;however,a negligible removal of carbamazepine and low removal of venlafaxine was observed(<20%).The study suggested that the SRT of 45 days in MBR could provide maximum treatment efficiency via decreasing membrane clogging.The effect of sludge age and pharmaceutical presence on the bacterial community was investigated via high-throughput sequencing.The study reveals that the variation in SRT affects the dynamics of the bacterial community significantly.For instance,the dominant bacterium Caldimonas of SRT 100 was disappeared at lower SRTs.Moreover,the profile of the dominant genus of the SRTs varied greatly from each other. | Bhagyashree Tiwari Balasubramanian Sellamuthu Sarah Piche-Choquette Patrick Drogui Rajeshwar Dayal Tyagi Marc Antoine Vaudreuil Sebastien Sauve Gerardo Buelna Rino Dube | 2021 | Systems Microbiology and Biomanufacturing2021，1，4： | 0 |
