Biodegradation of Reactive Orange 16 Dye in Microbial Fuel Cell: An Innovative Way to Minimize Waste Along with Electricity Production.

Microbial fuel cell (MFC) is an attractive green technology which harnesses the power of microorganism for the production of electricity along with bioremediation of waste. However, the bioremediation of the high concentration of dye wastewater in MFC remains unclear. In present study, double-chambered MFC inoculated with mixed bacterial consortium was used for bioremediation of reactive orange 16 (RO-16) dyes at a very high and variable concentration range of 100 to 1000 ppm.

Analysis of Metabolites and Carbon Balance in the Biofilteration of Cumene Using Loofa Sponge as Biofilter Media.

A laboratory-scale biofilter study was performed to treat cumene-inoculated mixed culture of bacterial community and loofa sponge (Luffa cylindrica) as support media for a period of 120 days in five distinct phases. The removal efficiency was obtained in the range of 40-85 % with maximum elimination capacity of 700 g m(-3) h(-1) at the inlet load of 1167 g m(-3) h(-1). The result demonstrated that loofa sponge is good support media for the removal of cumene at higher loading rates.
