摘要

(57) Abstract This invention, regards the production method of method and the selection media and the selection media which select the transformant where the imported gene is introduced making use of the vector of the landlord and this invention which are converted with the vector and that vector which include the polysaccharide disassembly enzyme gene as the selected marker character. As for the vector due to this invention, usage is simple former -garakutoshidaze as the selected marker in comparison with the vector which it includes. Including the reagent which is used for revealing the color, entire cost is very cheap. It possesses the advantage where it can utilize in the host cell of extensive.
