Production Of Gibberellic Acid And Cytokinin By Phanerochaete Chrysosporiumme446 Immobilized On Polyurethane Foam, Serpi̇l Ünyayar Jan 2000

Production Of Gibberellic Acid And Cytokinin By Phanerochaete Chrysosporiumme446 Immobilized On Polyurethane Foam, Serpi̇l Ünyayar

Turkish Journal of Biology

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.

Production Of Auxin And Abscisic Acid Byphanerochaete Chrysosporiumme446 Immobilizedon Polyurethane Foam, Serpi̇l Ünyayar, Eli̇f Ünal, Ali̇ Ünyayar

Turkish Journal of Biology

The fungus Phanerochaete chrysosporiumME446 was entrapped on polyurethane foam to synthesize auxin and abscisic acid (ABA). The maximum amounts of auxin produced on the 18 th day in both free and immobilized cells were 55.91mg/mL and 76.07mg/mL, respectively. Maximum ABA concentrations on the 12 th day in both free and immobilized cells were 6.87 mg/mL and 10.69 mg/mL, respectively. An immobilized system of auxin and ABA production resulted in a comparatively higher yield than free fungal mycelium.
