COMPARISON OF THE PHENOLIC COMPOUNDS CONTENT AND COMPOSITION IN SYNECHOCYSTIS SP. AND DESERTIFILUM THARENSE

Abstract

The content and composition of phenolic compounds in Synechocystis sp. PCC 6803 GT-L and Desertifilum tharense were studied for the first time. A spectrophotometric method was used to determine the phenolic compounds content, thin-layer chromatography and UV spectrometry to study their composition. A higher accumulation of these secondary metabolites was found in Synechocystis sp., which was almost twice as high as that in Desertifilum tharense. In both cases, the higher content of phenolic compounds was observed in the linear phase of cyanobacteria growth (3 days). Synechocystis sp. and Desertifilum tharense characterized by the formation of phenolics (4 and 7 compounds, respectively), which contain p-oxybenzoic or p-coumaric acids – the initial stages’metabolites of the phenolic compounds biogenesis.
