Chromatography, which is a laboratory technique for the separation of a mixture, can be used to determine which microorganisms are good at producing and decomposing the polymers.
Polyhydroxyalkanoates or PHAs are polyesters produced in nature by microorganisms, including through bacterial fermentation of sugar or lipids. PHAs are thermoplastic that can be processed on standard processing equipment.
Microorganisms produce PHAs due to their physiological stress. They synthesize PHAs as a carbon and energy store for future use when other energy sources are not available.
Microorganisms and microbes can also break PHA down into water and carbon dioxide.
Chromatography is a physical method of separation that distributes components to separate between two phases, one stationary (stationary phase), the other (the mobile phase) moving in a definite direction.
Chromatography is used to identify the type and quantity of polymer within the microorganism.
