PURPOSE:A composition for culture media, containing carrageenan and galactomannan in a specific proportion, soluble at low temperatures in a short time, capable of giving formed very transparent gels, and stable to cultivation for a long period. CONSTITUTION:A composition obtained by incorporating (A) carrageenan, e.g. kappa-carrageenan, with (B) galactomannan, e.g. locust bean gum, to give 0.5- 70wt% component (B). Preferably, the component (A) contains >=50wt% kappa- carrageenan, and the ratio of potassium ions to counter cations is >=50wt%.
