Microzym project focuses on estimating the rates of microbially mediated processes in the rhizosphere of maize plants by coupling the microbial and enzymatic functional traits with visualized oxidative and hydrolytic processes of organic substances decomposition. For this, we are optimizing the novel technique "time-lapse zymography" which allows to see the enzymatic activity distribution on the surface of intact roots by using fluorogenic substrates and UV light. In addition, we perform respirometry and microcalorimetry to determine microbial growth. Overall, I focus on the drought stress and nutrients availability in order to enhance the genotype effect of a root-hair deficient mutant maize as compared to a wild type, and two substrate textures (loamy and sandy soil). Those, from the scale of rhizoboxes, to the contribution in core field and column experiments of the Priority Program (SPP2089).
CV / Scientific Career

Double International Master Degree in Biotechnology of Environment and Health by University of Oviedo
(Spain) and Monterrey Institute of Technology and Higher Education (México)
2014 - 2019
Degree in Biochemistry with a specialization in biotechnology, University of Málaga (Spain). Degree thesis on the study of a microbial consortium of rhizobacteria with biological activity against a pathogenic fungus on avocado plants.
I have participated in several European Solidarity Corps projects related to permaculture and sustainability, including Environmental Education workshops for local youth, for which I feel special interest. These projects gave me the ability to communicate in multicultural and multidisciplinary environments, as well as improve my scientific dissemination.
