摘  要:
Objective:This paper presents pilot study on extraction and purification of costliness phycobiliproteins abound in Spirulina maxima.Methods:tissue-trituration method,freezing/unfreezing method and ultrasonic method were applied and compared to prepare crude extracts.Further purification was performed by means of ammonium sulphate precipitation and hydroxylapatite(HA)column chromatogram.Purified protein were examined through absorption spectrum and SDS-PAGE.Results:The results showed that ultrasonic method was the optimal method for extracting phycobiliproteins, and twice hydroxylapatite(HA)column chromatograms have to be performed to obtain fine product.Conclusion:considering cost of economy,manpower and time,this technology is useful in large-scale isolation and purification of phycobiliproteins in Spirulina maxima.
