Superior dimethyl disulfide degradation in a microbial fuel cell: Extracellular electron transfer and hybrid metabolism pathways

Roles of Biofilm Structure and Functional Genes in Overcoming Limited Dimethyl Sulfide Degradation and Energy Recovery

“…For instance, a power density as low as 0.237 mW m –2 had been reported with DMS as the sole substrate . Meanwhile, in a dimethyl disulfide driven MFC, the power density was also only 5.4 W m –3 . Hence, the limited energy recovery in MFCs caused by the toxic property of VOCs was significantly overcome in the PANI@CNT-MFC compared to the literature results (Table ).…”

“…Nonetheless, due to the toxicity of VOSCs to microorganisms, the power density was found to be rather limited. 10,11 The challenges on refractory VOSCs removal and fast energy generation in MFCs remain to be addressed. 12,13 In order to enhance the removal efficiency of refractory pollutants and related power generation in MFCs, several strategies have been adopted.…”

“…Volatile organic sulfur compounds (VOSCs), such as dimethyl sulfide (DMS), methanethiol (MT), and dimethyl disulfide (DMDS), significantly contributed to the generation of malodors in bodies of water due to their low olfactory threshold and high odor intensity. − In fact, VOSCs existed in all the stages of wastewater treatment, which may give rise to localized water issues. , To meet the demand of waste gas odor control, biodegradation technologies, including biofilters, biotrickling filters, and bioscrubbers, have been widely recognized for their environmental friendliness and high cost-effectiveness. , Among different biodegradation processes, the microbial fuel cells (MFCs) are known to eliminate organic pollutants and generate electrical energy simultaneously, taking advantage of biocatalysts in the bioanode. , For VOSCs degradation, several dual-chamber MFCs had been developed. Nonetheless, due to the toxicity of VOSCs to microorganisms, the power density was found to be rather limited. , The challenges on refractory VOSCs removal and fast energy generation in MFCs remain to be addressed. , …”

Exploring ozone formation rules and concentration response to the change of precursors based on artificial neural network simulation in a typical industrial park

“…Meanwhile, the State Council requires governments at all levels to promote the action of withdrawing from the city and entering the park , resulting in enhanced production concentration within these parks alongside intensified pollutant emissions [ [8] , [9] , [10] , [11] ]. The atmospheric condition in industrial parks is different with that in relatively low polluted areas, due to the characterization of small-scale, dense enterprises and various chemical and complex production processes [ [12] , [13] , [14] ], as well as the intermittent and fugitive emissions of VOCs [ 15 , 16 ] and the inevitable emissions of NO X [ 17 , 18 ], resulting in more complex in O 3 formation rules [ 19 ].…”
