“…Therefore, in order to study Cr(VI) reduction at different pH values, all catholytes contained 200 mM lactate which is a known metal chelator that can form chelates with Cr(III) (Hamada et al 2005;Puzon et al 2005) and thus enhance the Cr(VI) electroreduction process by limiting Cr(III) electrodeposition on the cathode (Xafenias et al 2013). The reason we used lactate among other metal chelators is that it occurs naturally in the environment, it exhibits low environmental toxicity (Bowmer et al 1998), it is easily biodegradable by bacteria of environmental interest like Shewanella (Pinchuk et al 2011) and can be used as an electron donor for Cr(VI) bioremediation (Brodie et al 2011;Alam et al 2006).…”

The work investigated the efficiency of microbial fuel cells (MFCs) for the treatment of alkaline hexavalent chromium containing wastewater. When lactate was used as the metal chelator in alkaline (pH 8) abiotic cathodes, hexavalent chromium concentration dropped from 10 mg l -1 to undetectable levels within the first 45 h of operation. Power density produced in the pH 8 abiotic cathodes was up to 21.4 mW m -2 , and in the pH 9 cathodes up to 2.4 mW m -2 ; these values were well comparable with other values found in the literature for biologically catalysed cathodes, even at lower pH values. When Shewanella oneidensis MR-1 was present in a hexavalent chromium reducing cathode at pH 8, current production contributed by 26 % to the total hexavalent chromium reduced during the 36 days of operation. On the other hand, when hexavalent chromium (10 mg l -1 ) was controllably added in the anode where S. oneidensis MR-1 was present, up to 73 % of current decreased immediately after every hexavalent chromium addition; this toxic effect remained even after hexavalent chromium was depleted in the anode and strongly indicates that the presence of hexavalent chromium in the anodes of MFCs must be avoided. Overall, our results indicate that alkaline hexavalent chromium wastewater can be effectively remediated in the cathodes of MFCs, provided that a metal chelator is present in the cathodes and that hexavalent chromium is not present in the anodes.

“…Experts suggest that ethyl lactate could replace the traditional solvents in more than 80% of their applications [1]. The unique properties like, 100% biodegradability, reduced eco-toxicity [2], non-carcinogenic, non-corrosive solvent, non-ozone depleting, high solvency power for resins and polymers makes it a promising solvent. Ethyl lactate (EL) has been used in a wide variety of applications, effective paint strippers, graffiti ink remover [3], in pharmaceutical industry as a dissolving/dispersing excipient, cleaning agent, effective in the removal of copper from contaminated soils [4], magnetic tape coating [5].…”
