Antagonistic activity of Pseudomonas chlororaphis against some mold fungi

Abstract

The paper presents a study of the antagonistic potential of Pseudomonas chlororaphis VKM B-3546D, isolated from the soil, against mold fungi Alternaria brassicicola VKM F-1864 and Aspergillus unguis VKM F-1754. P. chlororaphis VKM BS-1393 was used as a control culture of bacteria. It was revealed that in the presence of bacteria, the growth rate of mold fungi decreases by 10,2 mm/day. in the presence of P. chlororaphis VKM BS-1393, and by 12,9 mm/day. with P. chlororaphis VKM B-3546D, while the average increase in the colony of Alternaria is 10% and 20%, and aspergillus is 30% and 40%, respectively. It was shown that the degree of inhibition of the average colony growth in the native strain of pseudomonas is 7% higher than the contro strain for A. brassicicola VKM F-1864, and 10% for A. unguis VKM F-1754. Thus, the strain of P. chlororaphis VKM B-3546D turned out to be more effective, than P. chlororaphis VKM BS-1393.
