CULTIVATION OF PHOTOSYNTHETIC MICROORGANISM AND PRODUCTION OF EXTRACELLULAR POLYSACCHARIDE

摘要

PROBLEM TO BE SOLVED: To provide a method for culturing a photosynthetic microorganism high in utility, generating efficiency of a polysaccharide and utilizing efficiency of a light, and a method for producing an extracellular polysaccharide. ;SOLUTION: This method for culturing a photosynthetic microorganism comprises using agar-agar as a comprehensive immobilizing carrier and culturing it to obtain an N/P ratio in a culturing solution of ≥3. In the method for producing a polysaccharide derived from a microorganism by culturing the photosynthetic microorganism generating an extracellular polysaccharide using an immobilizing carrier, agar-agar is used as the comprehensive immobilizing carrier and the photosynthetic microorganism is cultured to cause the N/P ratio in the culturing solution of ≥3 to generate the objective extracellular polysaccharide.;COPYRIGHT: (C)1999,JPO
