Removal of sodium dodecyl sulphate from wastewater and its effect on anodic biofilm and performance of microbial fuel cell

Ultrafiltration membrane bio‐fuel cell as an energy‐efficient advanced wastewater treatment system

“…The microbial dynamic study confirmed that the inoculum majorly consisted of Pseudomonas (13.79%), Cloacibactrerium (7.03%), Peptostreptococcaceae (6.73%), Thiobacillus (6.77%), etc. as reported in our earlier paper 21 …”

“…as reported in our earlier paper. 21 The synthetic wastewater with sucrose as a carbon source was supplemented as a feed with trace nutrients with an average COD concentration of 2026 ± 61 mg /L. 22 Over an operational period of 90 days, the synthetic sucrose-based wastewater was fed to the UFBFC followed by fish processing wastewater for another 30 days to validate the system's performance for the natural wastewater treatment with an average initial COD concentration of 1915 ± 63 mg/L.…”

Role of bioelectrochemical systems for the remediation of emerging contaminants from wastewater: A review

“…Furthermore, Chakraborty et al [54], evaluated the effect of sodium dodecyl surfactant (SDS) removal on anodic biofilm in an MFC and reported Acinetobacter and Pseudomonas are the most abundance genus found in MFC with SDS, which are responsible for the degradation of SDS (more than 70%) in anaerobic environment with an initial SDS concentration of 10 mg L −1 . The removal mechanism follows the desulphurization of long alkyl chain of SDS and the enzyme alkyl sulphatase identified in Pseudomonas sp.…”

“…Wen et al reported that with the increase in Tween-80 concentration from 0 to 80 mg L −1 , the improvement in maximum power density from 0.6 to 5.2 W m −2 was observed, which can be attributed to the reduction in electron transfer resistance owing to improved cell membrane permeability; thereby, increasing electron transfer rate and consequently leading to more power production [114]. Recently, in terms of degradation of surfactant (SDS), Chakraborty et al revealed that about 70% of SDS removal was achieved in MFC with initial concentration of 10 mg L −1 with the retention time of 12 h [54]. Moreover, the maximum power density of 12.7 W m −2 was also obtained with 10 mg L −1 of SDS, which is about 2.65-folds less compared to control MFC with L-cysteine as carbon source due to increased toxic effect of SDS toward exoelectrogenic microbes [54].…”

Thus, the above discussed demonstrations prove that MFC can be efficacious in the degradation of ECs along with energy harvesting.…”
