    • Natural transformation in Streptococcus gordonii biofilm 

      Rahman, Fatema (Master thesis; Mastergradsoppgave, 2011-06-01)
      Natural transformation is one of the three mechanisms of horizontal gene transfer by which bacteria are able to take up free DNA from the surrounding environment. In natural ecosystems, bacteria preferentially attach to surfaces, forming matrix-enclosed communities known as biofilm. Biofilm cells differ phenotypically and physiologically from their free-floating counterparts. Objective: To estimate ...
