Research Topics:
We study functioning (growth, survival, interactions) of immobilized bacteria. Bacteria present in dairy products exist predominantly in an immobilized form, as coagulated milk is not a liquid and thus does not allow bacteria to move free. Bacteria may be immobilized by attachment to surfaces, chain formation and by trapping in the extracellular matrix. Use of semi-liquid medium to simulate immobilized growth revealed characteristic properties of non-planktonic lactococcal cultures, which are: limited distribution in the medium, slow growth, a mixture of the stationary and exponentially growing cells, and genetic instability of the culture. These characteristics depend on molecular composition of the cell wall. We have developed methods which allow to select mutations in cell wall related genes, important for immobilization. Our studies contribute to the identification of molecular determinants responsible for the phenomenon of adhesion, formation of biofilms, and more generally for functioning of Gram-positive bacteria in natural and industrial environments.


Organisms studied:
  • Lactobacillus lactis
  • Streptococcus agalactiae
  • Streptococcus pneumoniae


Special methods / technologies:
