EXTRACELLULAR SUBSTANCES OF TOTAL BACTERIAL FLORA FROM CULTURES OF THE GREEN ALGA SCENEDESMUS

The extracellular substances of concomitant bacteria of the green alga Scenedesmus cultures were studied, both in fresh and Black Sea water. Pentadecanoic and hydroxypentadecanoic acid dominate amid the lipophilic substances. Lactic and succinic acid and their esters are the main components of the water soluble material. Formation of esters in water medium is a proof of extracellular bacterial esterication
