Alginate and whey proteins were the most adequate polymers, except for <i>Lactobacillus acidophilus</i> Ki and <i>Lactobacillus casei</i> 01 at 2% (m/v) alginate. Xanthan gum appeared to be a potential vector for three strains. L-carrageenan was adequate for both <i>Bifidobacterium</i> strains, but not for<i> Lactobacillus</i> at 2% (m/v). <i>Bifidobacterium</i> strains were not negatively affected by cellulose acetate phthalate, while the opposite held for<i> L. acidophilus</i> strains. Chitosan was the poorest polymer for immobilisation of probiotic bacteria. 收起
