[Population composition of Actinomyces tumemacerans and Actinomyces albus var. fungatus]. 1978

V D Kuznetsov, and S Sabirov, and S N Filippova

The population analysis of Actinomyces tumemacerans and Actinomyces albus var. fungatus has revealed identical homologous series of spontaneous variants, this suggesting the genetical relationship of the cultures. Variants of the same type (basic, oligosporous, asporogenous and proactinomycete-like) are identical not only according to their individual properties (Kuznetsov, 1973) but also in total characteristics typical of the variants of a given species. Populations of the studied cultures comprise variants synthesizing several antibiotics, i.e. albofungin, albonursin and tetraene (basic and oligosporous variants), albofungin and tetraene (asprogenous green variants), as well as variants producing only one tetraene antibiotic (proactinomycete-like variants). Therefore, the population analysis based on the law of homologous series in hereditary variability of actinomycetes can be used as a new approach to the taxonomy of these microorganisms.
