Accompanying Bacteria in Cultures of Cyanoprocaryota and Green Algae

The dynamics of development of accompanying bacteria in cultural media of Cyanoprocaryota and Chlorophyta are conditioned by the extent of physiological activity of algae. The content and composition of dissolved organic matter is changing at different stages of culture growth. Non-volatile organic substances prevail during the lag phase, and also at the end of the exponential phase, whereas volatile organic substances dominate at the beginning of the exponential phase and during the period of intensive development of algae. The total numbers and biomass of accompanying bacteria are in direct agreement with the concentration of dissolved organic matter and in inverse dependence with the content of its volatile components. Depending on the stage of culture growth, the contribution of bacterial biomass to the total biomass of Microcystis aeruginosa was 3.32–12.26%, whereas its contribution to the total biomass of Scenedesmus acutus accounted for 0.30–5.74%. The maximum value of this index was registered during the lag and stationary phases of culture growth, whereas its minimum value was observed during the exponential phase of culture growth.
