Deconvolution of a biofilm involved in biocorrosion of metal alloys
Abstract
Bacteria are considered the primary colonizers of inanimate surfaces in both natural and man made environments through biofilm formation. Biofilm formation develops in a short period of time and depends on the EPS secretion capacity of each species. Since EPS (ExoPolySacharides) is remarkably important as a crucial facilitating factor in biofilm formation, in this project we will focus in the study of it, aiming to separate and identify the different components of this EPS, generated during the formation of a biofilm in alloy 7075 T6 during the corrosion process of this material. But we will also study the other components of the biofilm, including microorganisms, proteins, enzymes and even gases produced within the biofilm. Traditionally, biofilm formation and metallic corrosion have been studied as independent processes that occur simultaneously or sequentially. The novelty of the experimental approach of this work resides in the implementation of some omics analysis to study the biofilm composition including its different components: microorganisms, EPS, proteins, enzymes. This will certainly provide additional information which will allow us to have a better understanding of the complex metabolic phenomena of biofilm formation.
