2PHA can synthesize novel polymers

Many natural PHA mainly restricted the growth of microorganisms in the case of accumulation in the body as energy and carbon source Lactic acid esters of (HA) thermoplastic polyesters are synthesized by microorganisms biodegradable material. In PHA produced by numerous microorganisms, found the earliest, the most widely distributed of PHB.
Although the synthesis of PHB can be completed in the laboratory, but not biosynthetic PHB has a price advantage, but also meet the requirements of green chemistry and has broad prospects. Under natural conditions, the bacteria in the mass fraction of PHB only 1% -2%, but through the N, O, P, and the control of mineral ions, bacteria will greatly increase the content of PHB. In addition, through lactic acid powder and genetic engineering techniques to get the "transgenic plant", can improve the yield of PHB, but also a new type of synthetic polymers, and has broad prospects.
