Abstract

See full text

A bioelectrochemical reactor (1) has an anode chamber (11) having at least two bioanodes (12, 13), and an anodic electrolyte (14) with an anodic electroactive microorganisms,—a cathode chamber (21) with at least one biocathode (22), and a cathodic electrolyte (24) with a cathodic electroactive microorganisms. The anode chamber (11) is separated from the cathode chamber (21) by, running from the anode chamber to the cathode chamber, a cation exchange membrane (31) and an anion exchange membrane (32). The cation and anion exchange membranes are separated from each other by an inter-membrane chamber (30), and means for applying a potential difference between the interconnected bioanodes and the biocathode/biocathodes. The bioanodes and biocathode/biocathodes have active surfaces such that the total active surface of the biocathode/biocathodes (22) is greater than the total active surface of the two bioanodes (12, 13). The arrangement includes a method for regenerating the activity of the bioanodes of the reactor and to the use of said reactor for the electrosynthesis of organic acids and/or alcohols from organic waste.
