Abstract

A study of lactic acid bacteria phages from the collection of Institute of Product Resources by transmission electronic microscopy was conducted. It was defined that the morphological characteristics of the studied viruses are typical for the representatives of Siphoviridae kind. Two main morphoforms, characterized by capsid shape and tail length were found. Phages with isometric heads of B1 morphotype dominated in the collection. Phages with heads of B2 morphotype made only 13 % of the total amount. Phages of B1 morphotype formed two subgroups by the tail size. The phages were among them, being species-specific to S. thermophilus - they had isometric heads and long tails. The absence of correlation between the characteristics of phages was established, namely virion morphology, negative colonies morphology and species-specificity.
