Abstract:A cold inducible protein was found in soluble proteins of Volvariella volvacea mycelium treated by low treatment. This protein was isolated and purified by electrophoresis technique. The isoelectric point of this protein is 6.79 and the result of SDS?polyacrylamide gel electrophoresis indicated that the cold inducible protein consists of two polypeptides with molecular weight 48000 and 70000 Da respectively.
