Correct medium for determining lactobacilli.Peer-reviewed article

J. ŠAVEL

The article deals with the selective determination of lactobacilli in samples containing beside lactobacilli also pediococci. To suppress pediococci cadmium chloride was used an effective chemical. Medium taken for experiments was essentially fermented wort with some admixtures. To inhibit Gram-negative bacteria phenylethanol [in 0,3% volumetric concentration] was added to the basic medium. As to the cadmium chloride 10 mg/l can be recommended for routine analyses and medium without phenylethanol and 5 mg/l for medium  with it. Such concentrations are high enough to suppress pediococci and in some cases reduce also the growth of lactobacilli.
