Indicators of Life Conditions of the Baikal Sponge When Keeping It in Aquariums with the Use of Mass Spectrometry and Liquid Chromatography

Methods of chromatography mass spectrometry and microcolumn high performance liquid chromatography have been used to study complex biological systems. Potentialities to apply these methods have been disclosed by the example of biochemical research of symbiotic community of the endemic Baikal sponge Lubomirskia baicalensis (Dybowsky, 1874) when it is kept both under natural and under simulated conditions. It has been demonstrated that the use of a complex of modern methods of biochemical analysis allows effective, rapid determination, high sensitivity detecting of changes in biologically active compounds in living organisms.
