[Comparative study of the phage sensitivity of actinomycetes and their Nocardia-like variants]
Abstract:
The work was aimed at studying the resistance of three streptomycetes (Streptomyces chrysomallus, S. azureus and S. roseoflavus var. roseofungini) and their spontaneous Nocardia-like variants lacking aerial mycelium and spores against nine polyphages isolated mainly from soil. Some Nocardia-like variants were found to differ from their parent cultures in the resistance against certain actinophages. S. chrysomallus VKM Ac-590 and Ac-628 variants lost resistance against the phages. S. azureus VKM Ac-719 and S. roseoflavus var. roseofungini VKM Ac-770 variants became resistant to the phages. The changed phage resistance of the streptomycetes and their Nocardia-like variants was attributed to the disorganised process of adsorption (8 and 7%, respectively, against 70 and 90% for the parent strains).
