Abstract

The data on a and b chlorophyll content of unicellular algae incorporated into the symbiotic association of the Baikal sponges Lubomirskia baicalensis and Baikalospongia bacillifera are obtained by means of microcolumn reverse-phase high-performance liquid chromatography with UV detection. A connection between the number of chlorophylls and the depth of sponge habitat is demonstrated. A stronger decrease of chlorophyll content with depth increase is observed in Lubomirskia baicalensis.
