 We are all, I am Josep Lluís, from Irtejiro, from Barcelona. We might be fet pieces on studying the money in the nation in an aerobic digestion and also design a traffic process that occurs to overcome this limitation, as an example could be the acetate oxidation through the interaction between metanogell i carkea and cell bacteria. For that, we have characterized the effect of different supermaterials on the biofilm enrichment. Moreover, we have performed in-depth characterization of microbial populations through next generation sequencing, combined with metagenomic analysis. Finally, we have been applying new strategies to obtain more details about these populations and how to detect and monitor that communities. Well, this is me and this is my job place. Thanks for your attention and it will be a pleasure for me to give more details and information in València.
