     marine algae represents a sustainable feedstock in microbial fuel cells (mfcs) due to its low water and energy requirements for cultivation, higher capacity to sequester carbondioxide, and high carbohydrate content. two-compartment mfcs were evaluated under batch-fed mode using laminaria saccharina as the model for algae-based electron donor, and mixed microbial consortia as the biocatalyst, in the anode compartment. thelaminaria-based mfcs (lbms) were studied with three different pretreatment conditions for the l. saccharina: (i) autoclaving (auto), (ii) microwave irradiation (micro), and (iii) as received treatment (no-treat). a control was setup to establish base line performance for two-compartment mfcs using glucose as the electron donor in the anode. the performance of lbms (250 mw/m2 and 900 ma/m2) was on par with glucose-based mfcs. ac impedance analysis revealed that the charge transfer resistance was at least 50-fold higher than the corresponding ohmic losses in both lbms and glucose-based mfcs.
