The paper presents a study of the antifungal activity of the pigment-forming strains Janthinobacterium lividum VKM B-3515, Pseudomonas chlororaphis VKM B-3546D and their mixture against the test culture Aspergillus unguis VKM F-1754. The growth rate of the colony and the average growth of A. unguis VKM F-1754 in the presence of J. lividum VKM B-3515 were 46.3% lower than the control variant. The growth rate of fungi in the presence of a mixture of two bacteria was 32% lower than in the control, and in the variant with a pure culture of Pseudomonas, it was 21%. The average increase in the diameter of the colonies of A. unguis VKM F-1754 cultivated with (P. chlororaphis VKM B-3546D-J. lividum VKM B-3515) was 33% lower than the control variant with Pseudomonas. While the mixture (P. chlororaphis VKM B-3546D-J. lividum VKM B-3515) showed less activity compared to the pure culture of J. lividum VKM B-3515. Thus, the use of two strains together may not be appropriate.
