Production of Gibberellic Acid and Cytokinin By Phanerochaete chrysosporium ME446 Immobilized on Polyurethane Foam

Authors: SERPİL ÜNYAYAR

Abstract: The fungus Phanerochaete chrysosporium ME446 was entrapped on polyurethane foam to synthesize gibberellic acid (GA 3 equivalent) and Cytokinin (zeatin equivalent). Maximum gibberellic acid was defined on the 6 th day (44.43 µg/mL and 61.22 µg/mL, respectively) in both free and immobilized cells. Maximum cytokinin was defined on the 12 th day (9.61µg/mL and 16.33 µg/mL, respectively) in both free and immobilized cells. An immobilized system of gibberellic acid and cytokinin production resulted in comparatively higher yield than free fungal mycelium.

Keywords: Phanerochaete chrysosporium ME446, immobilization, polyurethane foam, gibberellic acid, cytokinin.
