The Model Associations of Cyanoprokaryota and Actinomycetes

In experimental associations of Cyanoprokaryota and Actinomycetes isolated from natural algal-bacterial mats of hypersaline lakes of Crimea the specific interactions of Oscillatoria terebriformis (Ag.) Elenk. (Cyanoprokaryota) and Streptomyces odorifer (Rullman 1895) Waksman 1953 were revealed. They included: positive tropism of streptomyces hyphae to O. terebriformis; stimulation of photosynthetical activity of O. terebriformis in association with streptomyces comparing to monoculture; changing of antimicrobial properties of association in comparison with monocultures of Streptomyces and Oscillatoria. Functional role of actinomycetes in natural algal-bacterial mats is discussed.
