摘要: Methods for using ionic liquids to extract and separate a biopolymer from a biomass containing the biopolymer are disclosed. Methods for dissolving a biopolymer in an ionic liquid are also disclosed. A recovery solvent is used to reduce the solubility of the biopolymer in the ionic liquid and conventional separation techniques are used to recover the biopolymer. Biopolymers encompassed by this invention include chitin, chitosan, elastin, collagen, keratin and polyhydroxyalkanoate.
