“…Algae are produced in abundance in high-rate algal oxidation ponds from the tertiary phases of the sewage treatment process [41]. Algae have previously been used as feedstock for MFCs as powders [20,21], or pre-treated microalgae [42] and macroalgae [43]. Phototrophic biofilms grow in response to light, carbon dioxide and inorganic nutrients where the availability of nutrients influences the type of biofilm formed [44].…”

a b s t r a c tThis paper describes the potential for algal biomass production in conjunction with wastewater treatment and power generation within a fully biotic Microbial Fuel Cell (MFC). The anaerobic biofilm in the anodic half-cell is generating current, whereas the phototrophic biofilm on the cathode is providing the oxygen for the Oxygen Reduction Reaction (ORR) and forming biomass. The MFC is producing electricity with simultaneous biomass regeneration in the cathodic half-cell, which is dependent on the nutrient value of the anodic feedstock. Growth of algal biomass in the cathode was monitored, assessed and compared against the MFC power production (charge transfer), during this process. MFC generation of electricity activated the cation crossover for the formation of biomass, which has been harvested and reused as energy source in a closed loop system. It can be concluded that the nutrient reclamation and assimilation into new biomass increases the energy efficiency. This work is presenting a simple and selfsustainable MFC operation with minimal dependency on chemicals and an energy generation system utilising waste products and maximising energy turnover through an additional biomass recovery.

“…It is composed of proteins, carbohydrates and lipids, serves as nutrient source for the microbes. Hence use of algae biomass in MFC is a promising approach to generate electricity (Strik et al 2008;Velasquez-Orta, Curtis and Logan, 2009;Yuan et al 2011;Lakaniemi, Tuovinen and Puhakka, 2012;Rashid et al 2013;Kondaveeti et al 2014;Gajda et al 2015). Experimental data illustrated the feasibility and sustainability of using cynobacterial biomass as anodic substrate with microbial strain of B. firmus NMBL-03 in MFCal for bioelectricity generation.…”

Microbial fuel cells (MFCs) are bio-electrochemical devices that exploit microorganisms for producing electricity from a variety of materials, including complex organic waste and renewable biomass. In this study, the heterotrophic microbe, Bacillus firmus was used as the active bacterial component with synthetic waste waters for bio-electricity production. Three identical mediatorless and membraneless single chambered microbial fuel cells (MFCs) without catalyst was fabricated with different carbon source and operated in batch mode. The performance of these MFCs with glucose, hydrolyzed potato peel and hydrolyzed cyanobacterial biomass substrates were comparatively evaluated. Among these substrates hydrolyzed cyanobacterial biomass was found to be the favorable substrate for electricity production whereas potato peel was unable to construct a well-established MFC. The maximum power density of 16.46mW/m2 at 62.48mA/m2 was achieved using cyanobacterial mass as the substrate. A current density of 53.47mA/m2 appeared to characterize the maximum power produced from a polarization test was 5.85mW/m2 for glucose substrate.

“…There are a few studies in literature that have examined the potential use of a BES anode to oxidise algal biomass (Inglesby et al, 2012;Nishio et al, 2013;Strik et al, 2008). The algal feedstocks used in these studies, however, were subjected to a pre-treatment (thermal, physical, chemical and biological) step (Cui et al, 2014;Hur et al, 2014;Kondaveeti et al, 2014;VelasquezOrta et al, 2009). This pre-treatment step was carried out with an assumption of difficulties to facilitate a hydrolytic, fermentation and/or a direct oxidation of algal biomass in a BES anode.…”

AbstractThis study examined for the first time the use of bioelectrochemical systems (BES) to entrap, decompose and oxidise fresh algal biomass from an algae-laden effluent. The experimental process consisted of a photobioreactor for a continuous production of the algal-laden effluent, and a two-chamber BES equipped with a graphite granules and carbon-felt anodic filter facilitating the physical removal and oxidation of the algal biomass from the effluent. Resultsshowed that the BES filter could retain ca. 90% of the suspended solids (SS) loaded. A coulombic efficiency (CE) of 36.6% (based on particulate chemical oxygen demand (PCOD) removed) was achieved, which was consistent with the highest CEs of BES studies (operated in microbial fuel cell mode (MFC)) that included additional pre-treatment steps for algae hydrolysis. Overall, this study suggests that a filter type BES anode can effectively entrap, decompose and in situ oxidise algae without the need for a separate pre-treatment step.
