| Popis: | Associations of cyanobacteria with actinomycetes are not being investigated. The purpose of this study is to investigate the biological aspects of coexistence of the free-living Anabaena variabilis with actinomycetes isolated from apogeotropic roots of Strangeria eriopus and Cycas micholitzii; with the cyanobacterium Oscillatoria terebriformis (Ag.) Elenk. emend., which were isolated from the natural cyanobacterial mat taken from the Kamchatkan thermal spring; and with actinomycetes isolated from the accumulating culture of cyanobacterium. Positive tropism of actinomycete hyphae to cyanobacterial trichomes and that of the cyanobacterium to streptomycetes were observed. Stimulation of growth of O. terebriformis in the associated culture with the streptomycete was recorded. The increase of fixation of nitrogen by A. variabilis and of photosynthetic activity of O. terebriformis in the associated culture with the streptomycete was recorded. |
