METHOD FOR SELECTING MICROORGANISM HIGHLY PRODUCING MACROPHOMOPSIS GUM AND METHOD FOR PRODUCING MACROPHOMOPSIS GUM USING HIGHLY PRODUCING MICROORGANISM

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a macrophomopsis gum in high yield with a microorganism belonging to the genus Macrophomopsis, to provide a method for selecting a microbial cell having high productivity of the macrophomopsis gum from microorganisms belonging to the genus Macrophomopsis and to provide a method for selecting a microbial cell effectively utilized during the selection thereof.;SOLUTION: The method for producing the macrophomopsis gum comprises a step of subjecting the microbial cell belonging to the genus Macrophomopsis to aerobic culture in a culture medium and collecting a β-glucan produced in the cultured product. A long filamentous microbial cell having slight branches is employed as the microbial cell (spawn) used for the culture.;COPYRIGHT: (C)2007,JPO&INPIT
