Seminar Dr Jimmy A. Martínez Ruano

Bioelectrochemical systems (BES) represent a promising platform for sustainable biochemical production by coupling microbial metabolism with electrochemical processes. This seminar explores the role of Clostridium species in the generation of organic acids (e.g., acetate, formate), alcohols (e.g., ethanol, 2,3-butanediol) and medium-chain carboxylic acids (MCCAs) such as caproate and caprylate through chain elongation pathways under heterotrophic growth and controlled electro-fermentative conditions. Emphasis is placed on the metabolic versatility of Clostridium, its extracellular electron transfer mechanisms and the influence of operational parameters such as pH, substrates, and electrode potential on product selectivity and microbial activity. The integration of BES with Clostridium under heterotrophic growth conditions presents a promising strategy for decentralized bioproduction, contributing to circular bioeconomy models and the reduction of carbon-intensive processes.
