Polyhydroxybutyrate PHB with CAS 26744-04-7 is produced by microorganisms, apparently in response to physiological stress conditions. It is mainly a condition of limited nutrients. The polymer is primarily a product of carbon assimilation (from glucose or starch) and is used by microorganisms as a form of energy storage molecule for metabolism when other common energy sources are not available.
