Abstract:
The purpose of this research was to investigate the antimicrobial properties of berries powders against pathogenic microorganisms, responsible for food alteration. The following autochthonous fruit from berries and groats were used: rosehip (Rosa canina), white sea buckthorn (Hippophae rhamnoides), hawthorn (Crataegus monogyna), grapes and aronia (Aronia Melanocarpa).The bacterial strains used as test organisms are S. aureus ATCC 25923, E.coli ATCC 25922, B. subtilis, S. Aboni, K. pneumoniae ATCC 13883. Antimicrobial activity was screened by an agar well diffusion method and bacterial growth was measured in liquid culture. For determination of MIC and MBC was done dilution technique.
