Determination of Poly(3-hydroxybutyrate) Content in Cyanobacterium Synechocystis sp. PCC 6803 Using Acid Hydrolysis Followed by High-performance Liquid Chromatography

Various photoautotrophic cyanobacteria accumulate intracellular poly(3-hydroxybutyrate) (PHB) granules. This protocol can be used for determining the PHB contents of the cells as % PHB weight per dry cell weight using acid hydrolysis followed by high-performance liquid chromatography (HPLC). This HP...

Sumario:Various photoautotrophic cyanobacteria accumulate intracellular poly(3-hydroxybutyrate) (PHB) granules. This protocol can be used for determining the PHB contents of the cells as % PHB weight per dry cell weight using acid hydrolysis followed by high-performance liquid chromatography (HPLC). This HPLC analysis is rapid, with a running time of approximately 5 min per sample. The technique can accurately determine PHB concentrations in the range of 2–1,000 μg/mL PHB. However, this technique is not applicable for determining the contents of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) in cyanobacteria.
