En el laboratorio estamos interesados en ver la expresión de genes que participan en el metabolismo energético de una gammaproteobacteria como Vibrio cholerae en diversas condiciones de crecimiento. Y por otra parte estudiar la toxicidad de algunos de estos genes al transformarlos en otra gammaproteobacteria como Escherichia coli.
