Characterizing the Anoxic Phenotype of Pseudomonas putida Using a Bioelectrochemical System.

ABSTRACT: Industrial fermentation in aerobic processes is plagued by high costs due to gas transfer limitations and substrate oxidation to CO₂. It has been a longstanding challenge to engineer an obligate aerobe organism, such as Pseudomonas putida, into an anaerobe to facilitate its industrial application. However, the progress in this field is limited, due to the poor understanding of the constraints restricting its anoxic phenotype. In this paper, we provide a methodological description of a novel cultivation technology for P. putida under anaerobic conditions, using the so-called microbial electrochemical technology within a bioelectrochemical system. By using an electrode as the terminal electron acceptor (mediated via redox chemicals), glucose catabolism could be activ
