Biochemical technology the basis of the combination of decalcification technology, biochemical, electrochemical and MBR technology, the invention currently manages wastewater from book production, is cost effective and high efficiency, and results in the wastewater that meets the standards. biochemical technology is entering the genomics era, the Center is in the process of converting a single laboratory operating from a biochemical laboratory to a network lab, leading to the development of a new biology center. Polymerase chain reaction (PCR) biochemical technology creating single curtains or a few copies of a piece of DNA in several orders of magnitude, it produces billions of copies of DNA sequences.
