  • Isolation, phenotypic and genotypic characterization of enterococci, isolated from different ecological niches
  • Examination of probiotic characteristics of enterococci and other lactic acid bacteria strains in order to design new probiotic and prebiotic preparations, as well as the characterization of molecular mechanisms in the basis of probiotic activities of natural isolates of lactic acid bacteria
  • Evaluation of negative impacts of antibiotics through analysis of genes for antibiotic resistance and other virulent factors present in enterococci isolated from different ecological niches
  • Production of inovative probiotic fermented drink for domestic animals
  • Microbiological control of probiotic lyophilized supplements (lozenges and capsules)
