a continuous industrial separation process for biopolymer extracts each individual single component from a stream of cell extract . the process can be set up as a mixed flow reactor or fluidized bed in a continuous operation under normal pressure to treat a volume of cell extract in a short period of time . the separated single biopolymer is continuously withdrawn from the process and be easily condensed into the desired concentration . a resin , which can be an ion exchanger or affinity adsorbent or dye ligand adsorbent or hydrophobic adsorbent or immunoadsorbent , is evenly suspended in a well mixed reactor to equilibrate with the biopolymers in the liquid phase . the fundamental separation scheme is successive adsorption and desorption of biopolymer from liquid . biopolymers are isolated into a single stream or multistreams for one component or many individual components . each stream contains only one high purity biopolymer . the new process has the advantages of short operation time and economical usage of resin and high production throughput for treating massive volumes of cell extract in a continuous mode .
