Biodegradation and detoxification of the triphenylmethane dye coomassie brilliant blue by the extracellular

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 2,   Pages 421-436 doi: 10.1007/s11705-020-1952-7

Abstract: Fungi play an important role in dying wastewater treatment. In this work, the mycelia of exhibited an excellent capacity in decolorizing coomassie brilliant blue (CBB). The results demonstrated that the mycelia could treat CBB with high concentrations over a broad range of pH and temperature. The decolorization rate of 99.19% and the removal rate of 16.31 mg·L ·h were realized. The mycelia could be recycled from decolorizing process for 19 times, indicating a good re-usability. It verified that the lignin peroxidase (121.65 U·L ) and manganese peroxidase (36.77 U·L ) were involved in the degradation and decolorization process of CBB. Toxicity assessments indicated the seed germination rate was up to 82.22% while inhibition to decreased dramatically and no significant effect on growth was found. The removal of CBB was a synergistic process accomplished by adsorption and biodegradation. The mycelia could be used for eco-friendly CBB treatment.

Detoxification and concentration of corn stover hydrolysate and its fermentation for ethanol production

Qing Li, Yingjie Qin, Yunfei Liu, Jianjun Liu, Qing Liu, Pingli Li, Liqiang Liu

Frontiers of Chemical Science and Engineering 2019, Volume 13, Issue 1,   Pages 140-151 doi: 10.1007/s11705-018-1714-y

Abstract: Environmental and energy concerns have increased interest in renewable energy sources, particularly biofuels. Thus the fermentation of glucose from sulfuric acid-hydrolyzed corn stover for the production of bioethanol has been explored using a combined acid retardation and continuous-effect membrane distillation treatment process. This process resulted in the separation of the sugars and acids from the acid-catalyzed hydrolysate, the removal of most of the fermentation inhibitors from the hydrolysate and the concentration of the detoxified hydrolysate. The recovery rate of glucose from the sugar-acid mixture using acid retardation was greater than 99.12% and the sulfuric acid was completely recovered from the hydrolysate. When the treated corn stover hydrolysate, containing 100 g/L glucose, was used as a carbon source, 43.06 g/L of ethanol was produced with a productivity of 1.79 g/(L?h) and a yield of 86.31%. In the control experiment, where glucose was used as the carbon source these values were 1.97 g/(L?h) and 93.10% respectively. Thus the integration of acid retardation and a continuous-effect membrane distillation process are effective for the production of fuel ethanol from corn stover.

Is sodium percarbonate a good choice in situ remediation of deltamethrin pollution?

Xu Zhang, Baigang Ren, Shangge Li, Xiaodi Qu, Huanhuan Yang, Shiguo Xu, Zongming Ren, Qiang Kong, Cheng Wang

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 3, doi: 10.1007/s11783-017-0931-9

Abstract: In this research, the toxic effects of deltamethrin (DM) on the behavior responses of Zebra fish ( ) in the characteristic of behavior strength were investigated followed by an assessment of an in situ remediation of the DM pollution using sodium percarbonate. Behavior strength of was approximately 0.83 in the control group and was slightly higher than 0.83 in the sublethal treatment (0.1 TU (toxic unit)), which suggested that sublethal DM exposure could induce a stimulation effect in 48 h of exposure. In lower DM concentration treatments (0.5 and 1.0 TU), behavior strength could be inhibited significantly. Behavior responses of showed a gradually increased tendency when they were exposed to higher concentration of DM, and the declining amplitudes of behavior strength changed with the increase of DM concentrations. These results suggested that DM had evident acute toxicity effects on the behavior responses of with a good dose-effect relationship. The in situ remediation of the DM pollution using sodium percarbonate showed that the toxic effect of DM on behavior responses of could be eliminated even in the highest concentration of DM (5.0 TU). Meanwhile, the behavior response of in the treatment of sodium percarbonate was the same as in the control, which indicated that sodium percarbonate had no evident toxic effects on the behavior of in the current concentration. This study suggested that adding sodium percarbonate in situ might be a good way to eliminate the DM toxic effects.
