Determination of minimum inhibitory concentrations of lactic acid bacteria and other antagonist microorganisms

Minimum inhibitory concentrations of lactic acid bacteria and other antagonist microorganisms isolated from natural sources Kaliningrad region (soil, water bodies, plant objects) were determined. It was shown that the minimum concentration Pediococcus pentosaceus metabolites against Escherichia coli is 1.5·107 CFU/ml; Pseudomonas chlororaphis have no effect test strain under study . found damnosus adversely affect growth , but at a CFU/ml after 6-24 hours cultivation. For by Lactobacillus casei characteristic with respect to studied 1.5-107 CFU/ml, for fermentum 1.5·105 CFU/ml. At Bacteroides hypermegas (Megamonas hypermegale ) equal 1.5·106 an optical density lower than control observed. The syringae inhibiting culture Acetobacter aceti Psychrobacter urativorans lowest inhibit
