The suitability of lactic acid bacteria (Lactobacillus planatarum CCM 7039, Lactobacillus amylovorus CCM 4380) as starter culture for oat beverage fermentation was investigated. The fermentation was carried out at 37 °C for 36 h. The counts of lactic acid bacteria reached 8.55 log CFU cm3 after 24 h fermentation, from an initial concentration of log 7.23 CFU cm3 and pH decreased from 7.4 to below 3.8. The oat beverage inoculated with Lactobacillus plantarum CCM 7039 showed higher values of sensory parameters than oat beverage inoculated with Lactobacillus amylovorus CCM 4380. The oat-based substrate proved to be a suitable medium for the tested Lactobacillus strains.
