METABOLOMIC ANALYSES OF INTRACELLULAR DYNAMICS IN BLOOM - FORMING CYANOBACTERIUM MICROCYSTIS

Abstract

 In this study, we used metabolome analysis technology to investigate the intracellular dynamics of cyanobacterial groups that form blue-green algae. Specifically, we took samples of the blue-green algae formation from the water surface and at a water depth of 30cm in the morning and afternoon and at night, and conducted metabolome analysis on these samples. The analysis results showed variations in the metabolite were consistent with differences in the water depth (water surface and at a water depth of 30cm). This is also reflected in the sugar-nucleotide that forms the base of biofilm; hence, the low amount of extracellular polysaccharide is considered to be a reason why blue-green algae do not form within the water.
