Stimulative effect of Phaeodactylum tricornutum on the growth of Flavobacterium sp.

Abstract

      The effect of phytoplankton species Phaeodactylum tricornutum Bohlin (Diatomeae) on the growth of bacterial strain Flavobacterium sp. was inves­tigated in mixed culture at different temperatures, salinities and light intensities. Bacterial growth in the filtrate of algal culture medium was also observed. Stimulative effect of the alge P. tricornutum on the growth of bacteria Flavobac­terium sp. was established. Stimulation of bacterial growth was stronger when the growth of algal population was more intensive.
