97 different strains were selected from the rhizosphere of Juniper excelsa Bieb which is distributed over narrow foreland of the Black Sea in the Crimean peninsula from Sudac to Balaclava and over small area of Caucasus. Their antagonistic properties against gram-positive bacteria Bacillus subtilis ATCC 31324, B. cereus ATCC 14579, Staphylococcus albus ATCC 12228; phytopathogenic bacteria Erwinia amylovora E3, E. carotowora JN42, Pseudomonas corrugate 3’M, Clavibacter michiganensis subsp. Michiganensis 39’1, yeast Pichia guilliermondii 6260, Debaromyces hansenii VKM Y-2482, Candida famata VKM Y9 and mold Aspergillus awamori NF142 were investigated. Some of actinomyces strains have a wide range of antibacterial and antifungal properties. Several isolated actinomyces specifically inhibit growth of A. awamori, others – development of yeast. We proved effectiveness of the isolating different actinomyces strains that are able to repress development of the phytopathogenic bacteria and human pathogenes from the rhizosphere of juniper in the Crimean peninsula.
