Popis: Prunus padus, Ribes nigrum, Armoracia rusticana, Anethum graveolens, Allium cepa and Vaccinium vitis-idaea were tested as natural antimicrobials against extremely halophilic archaea causing spoilage of salty fern. Leaves of Prunus padus and Anethum graveolens had no effect on the growth rate of halophilic archaea a. Leaves of Ribes nigrum statistically significantly stimulated growth of halophilic archaea. Leaves and roots of Armoracia rusticana demonstrated only a temporary antimicrobial effect which continued for less than 60 hours. Peel of Allium cepa and leaves of Vaccinium vitis-idaea demonstrated permanent inhibition of growth of halophilic archaea. Long-time experiment showed that both peel of Allium cepa (5.1 g per 1 kg of salty fern) and leaves of Vaccinium vitis-idaea (13.2 g of fresh leaves or 6.6 g of dry leaves per 1 kg of salty fern) totally prevent spoilage of salty fern.
