“…36,62,76,79,80 Similarly, the electrochemically active microbial consortia initially inoculated from municipal wastewater treatment plants and enriched with acetate as the electron donor can also change its composition and be adaptive to another contaminant. These results showed the bacterial diversity among electrochemically active microbial consortia as well as the bacterial various pathways for the degradation of different recalcitrant substances, 55,62,81,82 although in another case the dominant species were nearly unchangeable with the shift of substrates. 69 Thus, analysis and comparison of the phylogenetic diversity of the microorganisms within complex BESs is necessary to provide a significant insight into community dynamics which significantly affect the performance of BESs.…”

“…64 These results illustrated the capability of the microbial consortia to gradually adapt to the environment, in which the input of recalcitrant substrates and produced intermediates substantially changed the composition of the microbial consortia. 40,55,62,80 In another report, the dominant species did not change significantly with the addition of different substrates such as veratryl alcohol and glucose, whereas the abundance of some species increased greatly. 69 While the change in the composition of microbial consortia is still being debated, the different abundance in DGGE profiles sampling from BESs with different recalcitrant substrates cannot be correlated with its role in electron transfer between substrates and electrodes.…”

“…Comparatively, much attention has been paid to the composition of microbial consortia in BESs. 40,55,62,64,69,80 While the composition of microbial consortia in an acetate-fed system changed according to the shift of tested substrates from acetate to 1,2-dichloroethane, 62 the addition of indole obviously changed the microbial consortia in glucose-powered MFCs, not only their relative abundance but also the emergence of new species. 63 Similarly, microbial consortia previously inoculated from a 1,2-dichloroethane (1,2-DCA) contaminated site changed its composition at a rate of 9% per week after shifting to BESs in the presence of 1,2-DCA whereas microbial consortia initially enriched in the presence of acetate changed its composition at a high rate of 48% per week with shift to 1,2-DCA.…”

Recalcitrant wastes including dyes, pesticides, explosives, heavy metals, polyalcohols, furan derivatives and phenolic substances, are of special concern owing to their recalcitrance and persistence in the environment. Bioelectrochemical systems (BESs) including microbial fuel cells (MFCs) and microbial electrolysis cells (MECs), integrate three important wastewater treatment options, namely, biological treatment, electrolytic dissociation and electrochemical oxidation/reduction, and are regarded as a new sustainable and effective strategy for treatment of these wastes. The simultaneous and cooperative roles of these multiple units running in parallel in BESs contribute to the efficiency of recalcitrant waste treatment, while substrate metabolism is considered to be a key step triggering different unit operations. An up-to-date review is provided on recent research and development in BESs-based recalcitrant wastes treatment. MFCs and MECs, as two types of BESs, are summarized in terms of treatment efficiency, recalcitrant substance metabolic pathway and microorganism diversity after a brief introduction to the electrochemical process for recalcitrant waste treatment. The scientific and technical challenges that have yet to be faced in the future are also discussed.

Suitability of olive oil washing water as an electron donor in a feed batch operating bio-electrochemical system

et al. 2017

SUMMARY:Olive oil washing water derived from the two-phase manufacturing process was assessed as an electron donor in a bio-electrochemical system (BES) operating at 35 ºC. Start-up was carried out by using acetate as a substrate for the BES, reaching a potential of around +680 mV. After day 54, BES was fed with olive oil washing water. The degradation of olive oil washing water in the BES generated a maximum voltage potential of around +520 mV and a Chemical Oxygen Demand (COD) removal efficiency of 41%. However, subsequent loads produced a decrease in the COD removal, while current and power density diminished greatly. The deterioration of these parameters could be a consequence of the accumulation of recalcitrant or inhibitory compounds, such as phenols. These results demonstrated that the use of olive oil washing water as an electron donor in a BES is feasible, although it has to be further investigated in order to make it more suitable for a real application. KEYWORDS: Bio-electrochemical system; COD removal; Electricity generation; Electron donor; Olive oil washing watersRESUMEN: Idoneidad del agua de lavado de aceites de oliva como donador de electrones en un sistema alimentado por lotes bioelectroquímico. El agua de lavado del aceite de oliva procedente del proceso de elaboración en dos fases fue utilizada como donador de electrones en un Sistema Bioelectroquímico (BES) operado a 35ºC. Se realizó una etapa de arranque del sistema mediante alimentación con acetato, alcanzando un potencial de referencia de +680 mV. Tras 54 días, el sistema se alimentó con agua de lavado de aceite, generando un potencial máximo de +520 mV y una eliminación de materia del 41%, en demanda química de oxígeno. Sin embargo, cargas subsecuentes conllevaron una bajada en la eliminación de materia, mientras que la densidad de corriente y de potencia disminuyeron ostensiblemente. El empeoramiento de estos parámetros puede deberse a la acumulación de compuestos recalcitrantes o inhibidores, como fenoles. Por tanto, el uso del agua de lavado de aceite de oliva en un BES es factible, aunque es necesario llevar a cabo nuevas investigaciones que hagan más atractiva su aplicación a escala real.
