The paper investigated the effect of immobilization of bacterial cells Lactobacillus brevis 2k.Gv. on polyvinylpyrrolidone nanowires on viability and enzymatic activity of cells. The optical density of the culture solution and the growth rate of lactobacilli were measured using a Reverse-Spinner RTS-1 bioreactor to assess physiological activity of the immobilized cells. It is shown that immobilization is ‘soft’, the carrier dissolves in the culture solution after biofilm formation.
