ABSTRACT

Bacteria, as a heterotrophic component, are a part of various algal-bacterial communities (associations) formed in natural environments. The species composition of the accompanying microflora is studied most completely in a number of algal species from the genera Chlorella Beijer., Stichococcus Nag., Scenedesmus Meyen, Dunaliella Teod. and Spirulina Turp. Some evidence on satellite bacteria of algae from the genera Bracteococcus Tereg, Pleuchloris Pasch., Microcoleus Desmaz. and others is also available in literature. The results of the analysis of the data both from literature and original, testify to the constant and definite species composition of bacteria accompanying algae in culture and natural habitats. The specifity of the species composition of bacteria is manifested at the generic level of the primary producer, though there may be differences depending on the algal strain. Along with the taxonomic position of algae, the ecological conditions of their habitats in nature or in cultures are also crucial factors of the species composition of the heterotrophic component of algal-bacterial communities. The heterotrophic component is mainly represented by constant satellite bacteria of algae, including the dominant and minor species, in the number from 4 to 12 and more. However, in its composition there are also rarely occuring, random and infecting microorganisms, including antagonists and parasitic forms. Natural changes in dominant species of satellite bacteria are observed during the algal growth and development.
