AUREOBASIDIUM PULLULANS, CULTURE MEDIUM FOR β-GLUCAN PRODUCTION AND METHOD, AUREOBASIDIUM PULLULANS CULTURE PRODUCT AND COMPOSITION COMPRISING SAME

摘要

PROBLEM TO BE SOLVED: To provide Aureobasidium pullulans that provides β-glucan with higher yield and substantially free of melanin.SOLUTION: The present application provides a culture medium for β-glucan production. The culture medium of the present invention comprises a carbon source, a nitrogen source and ascorbate. The present application further provides a method of producing β-glucan, the method comprising a step of culturing Aureobasidium pullulans in a fermentation medium. The Aureobasidium pullulans is advantageous from the standpoint that melanin is not produced and as a result, the yield of β-glucan can be increased and by the improvement of the medium composition and culture method, waste products can be reduced.SELECTED DRAWING: None
