Microorganisms of agronomical and environmental interest


In our group basic and applied microbiology research lines are carried out. In terms of basic research, environmental contaminant degradation pathways are studied, as well as pathways regulating the formation of bacterial biofilms and their relationship with metal oxidation. Regarding applied microbiology, the group works following premises tending to solve agricultural and environmental problems. In this context, pathogenic bacteria that cause plant diseases, beneficial bacteria capable of promoting plant growth and bioremediating contaminants present in the environment such as metals and herbicides are studied.
