Full textMicroorganisms increase the opencircuit potential of stainless Steel immersed in seawater in a phenomenon called ennoblement.This change of potential of several hundreds of millivolts raises the chance of localized corrosion.The ennoblement has been studied for more than 40 years, and despite the importance and impact of ennoblement, little is known about the microbial mechanisms responsible for the phenomenon. We have combined microbial ecology and electrochemistry to investigate the diversity of surface attached bacteria associated with stainless steel ennoblement. Seawater temperature and dissolved oxygen content are factors that influence the ennoblement and we used them to infer the bacterial fraction associated with the phenomenon. The ennoblement is inhibited by a critical seawater tempzrature (above 38°C/40°C) and low dissolved oxygen content.With DNA amplicon sequencing, we identified operational taxonomie units (OTUs) that were biomarkers of the ennoblement. There were some OTUs affiliated to hydrocarbon degrading bacteria, and one OTU affiliated to ‘Candidatus Tenderia electrophaga’, an electrotrophic bacteria able to reduce oxygen with electrons from an electrode.We investigated the role of electrotrophic bacteria with potentiostatic and open circuit conditions and with metagenomics we recovered a metagenome assembled genome (MAG) very close to 'Candidatus Tenderia electrophaga’ associated with the ennoblement.From these results, we proposed a new bacterial mechanism to explain the ennoblement : electrotrophic bacteria would be able to reduce oxygen with électron drawn from the stainless steel passivation film, hence influencing the open circuit potential and therefore the ennoblement

Full textMicrobial fuel cells (MFCs), as a potentially sustainable biotechnology, can directly convert organic matter into electricity by using bacterial biofilms as biocatalysts. In a political context where European legislation favors and imposes the revalorization of organic waste from industries, MFC seems an inexpensive and promising technology to meet this need. The aim of this thesis is to improve knowledge of the formation of electroactive biofilms on the anodic surface, and to understand the mechanisms involved in the competition between electroactive bacteria (EAB) and other bacteria. Special attention will be paid to shear force as a tool to control the formation of anodic biofilms. First, bacterial successions have been studied under stationary conditions and in standard laboratory configurations. The results show that the formation of the biofilm is divided in two stages. At first, non-specific EAB grow in all MFCs, producing or not electricity. Then, specific EAB become predominant only in MFCs producing electricity and is associated to an exponential increase of electricity. From these results, we hypothesize that inhibition of the first step should decrease the competition between nonspecific and specific EAB. We propose to use the shear stress to select specific EAB during the adhesion. First, MFCs with a shear stress flow chamber configuration were designed, constructed and set up. The results show that the proportion of specific EAB such as Geobacter was higher, up to 30.14% as opposed to a lower shear stress (less than 1%). Then, the effect of shear stress on microbial selection during biofilm growth was studied. These results confirm the previous conclusions: specific EAB are selected when shear stress is higher. This work demonstrates the major role of shear stress in biofilm formation and could be a way to control the selection of EAB. This factor should be taken into account in the architecture and implementation of the reactors

Full textMany microorganisms have the ability to catalyze the electrochemical oxidation of organic matterby self-organizing into biofilm on the surface of anodes. This process is the basis of highlyinnovative electro-microbial processes such as microbial fuel cells or microbial electrolysis cells.The biofilm/electrode interface has been the subject of numerous studies whose conclusionsremain difficult to disentangle partly because of the diversity of the interfacial parameters involved.The purpose of this thesis work is to exploit microsystem technologies to focus the impact ofelectrode surface topography on biofilm development and electro-catalytic performance. Theformation of electroactive biofilms of Geobacter sulfurreducens was studied on gold electrodespresenting well-controlled topographies, in the form of roughness, porosity, pillar networks, atscales ranging from nanometer to a few hundred micrometers. The presence of micro-roughnessincreased the current densities by a factor of 8 compared to a smooth surface and its effect wasquantified using the Sa parameter. We have tried to distinguish the effects of different roughnessscales on biofilm development and electron transfer rates. The suitability of micro-porosity wasdiscussed. The increase of active surface area by the presence of micro-pillars has proved veryeffective and a theoretical approach has given keys to understanding and optimization. Theknowledge acquired under pure culture conditions was finally confronted with the use of multispeciesbiofilms formed from a complex inoculum coming from marine sediments
