[Growth and antimicrobial activity of an association of an actinomycete and a green alga].

During joint cultivation of the actinomycetes Streptomyces griseus (strains 65 and 744) isolated from the soil and the green algae Chlorella vulgaris larger amount of biomass as compared with solitary axenic culture have been shown. The relation of biomass of actinomycetes S. griseus strain 65 and S. griseus strain 744 and algae in the lichen-like experimentally formed thallom make up 42:1 and 40:1 relatively, i. e. the mass of actinomycetes forms 97-98% from the mass of thalloms. Actinomycetes in the associations with the algae accumulate larger amount of biomass that in the axenic cultures on corresponding medium, whereas the algae produce the same amount of the biomass as the axenic culture under the same conditions. The associations have the antimicrobic properties differed from the axenic cultures established.
