Development of reusable and long-term storable bacteria attached nanofiber mats for highly efficient removal of Cr(VI) and reactive dye from wastewater

Developing reusable, sustainable and long term storable bioremoval technologies is essential for removal of heavy metals reactive dyes in industrial wastewater. <i>Clavibacter michiganensis</i> (<i>C. michiganensis</i>) having bioremediation property was selected attachment, polysulfone (PSU) as the polymer matrices electrospinning nanofibrous webs. For this approach, nanofiber mats (PSU-NFMs) were produced by electrospinning, followed attachment bacteria onto a subsequent used Cr(VI) dye. The efficient with 100% yield achieved within 24 hours (10 ppm) attached mats. Also, nano bio-composite decolorized Reactive Blue (RB, 20 13 h. Furthermore, prepared to PSU-NFMs showed storage stability at 23 ± 2℃ 4℃ 30 days yields found potentially keeping bacterial cells alive. Finally, reusability determined after five cycles both pollutant 70.3% 51.8% dye capacities obtained. It expected that could be potential application wastewater treatment.
