Bacterial biotechnology (BIOBACT)

Description

Objetives

The research in bacterial biotechnology contributes, by the use of functional genomics and biotechnological processes, to generate quality knowledge useful for the identification and the development of bacterial strains, enzymes, and metabolites to improve the food elaboration processes or the microbial functionality in hosting organisms.

Research Lines

  • Identification, characterization, and genetic improvement of bacteria present in food substrates
  • Identification, characterization, production, and improvement of enzymes with technological interest
  • Development of biochemical and molecular methods for the detection of relevant bacterial traits
  • Systems Biology studies aimed at improving the functionality of bacteria in food processes and host-microbial interactions.
Capacidades

Skills

  • Biochemical and molecular techniques for the detection of bacteria and genes with technological interest.
  • Production and purification of recombinant enzymes
  • Genetic expression analysis
