Abstract (en)

[origin: WO0073455A1] The present invention relates to an economical method for biosynthesis of intended foreign proteins using transformed microalgae, that is to say, it relates to a method of using transformed microalgae as a bioreactor where economical biosynthesis of foreign protein is possible by transforming protoplast of microalgae such as <i>Chlorella ellipsoidea</i> with DNA vector containing intended foreign protein gene and then culturing it in a large scale. In particular, Sh ble gene, which is resistant to phleomycin, is used as a selection marker in the present invention.
