Bioplastic raw materials in microbes?

                                What if the sources for the degradable bioplastics are naturally and excessively available and renewable? Scientists have identified few microbes when under excess availability of carbon and with a controlled availability of oxygen, nitrogen, phosphorous, or pH fluctuations can produce raw materials of Bioplastics. Eg: polyhydroxyalkanoates (PHAs), are biologically produced polyesters produced by the fermentation processes of microbes. Extremophilic microbes especially the haloarchaea group of the Archaea domain is the interests of the scientists for the high ability to metabolically produce polyhydroxyalkanoate (PHA), polyhydroxybutyrate (PHB), and polyhydroxyvalerate (PHV). These compounds are found to be accumulated as granules within the microbes due to their characteristic lipid and hydrophobic nature, these granules are in crystallized form and are well protected from the metabolic water within the microbe by a well-protected strategy of being compounded by PHA polymer followed by phospholipid monomer with phasein proteins. The quantity of the phasein protein determines the size of the granules. Awesome right!
