TAILIEUCHUNG - Production of auxin and abscisic acid by Phanerochaete chrysosporium ME446 immobilized on polyurethane foam

The fungus Phanerochaete chrysosporium ME446 was entrapped on polyurethane foam to synthesize auxin and abscisic acid (ABA). The maximum amounts of auxin produced on the 18th day in both free and immobilized cells were and , respectively. | Turk J Biol 24 (2000) 769–774 © TÜBİTAK Production of Auxin and Abscisic Acid by Phanerochaete chrysosporium ME446 Immobilized on Polyurethane Foam Serpil ÜNYAYAR*, Ali ÜNYAYAR Mersin University, Art and Science Faculty, Department of Biology, 33342 Mersin-TURKEY Elif ÜNAL Mersin University, Faculty of Engineering, Department of Environmental Engineering, 33342, Mersin-TURKEY Received: Abstract: The fungus Phanerochaete chrysosporium ME446 was entrapped on polyurethane foam to synthesize auxin and abscisic acid (ABA). The maximum amounts of auxin produced on the 18th day in both free and immobilized cells were and , respectively. Maximum ABA concentrations on the 12th day in both free and immobilized cells were µg/mL and µg/mL, respectively. An immobilized system of auxin and ABA production resulted in a comparatively higher yield than free fungal mycelium.

Poliüretan Köpük Üzerine Tutuklanmış Phanerochaete chrysosporium ME446’dan Oksin ve Absisik Asit Üretimi Özet: Phanerochaete chrysosporıum ME446 oksin (IAA) ve absisik asit (ABA) üretmek amacıyla poliüretan köpük üzerine tutuklandı. Maksimum IAA hem serbest hem de tutuklanmış hücrelerde 18. günde belirlendi (sırasıyla µg/mL ve µg/mL). Maksimum ABA hem serbest hem de tutuklanmış hücrelerde 12. günde belirlendi (sırasıyla µg/mL ve µg/mL). IAA ve ABA üretiminde tutuklanmış sistem serbest fungal miselyumdan daha yüksek verim sağladı. Anahtar Sözcükler: Phanerochaete chrysosporium ME446, tutuklama, poliüretan köpük, oksin, absisik asit(ABA). Introduction Auxin (IAA) and abscisic acid (ABA) are known as plant growth regulators which have hormonal functions (1). They are mainly produced by plants (2,3), but they are also produced by fungi as primary or secondary metabolites (4). Microorganisms are widely used in industries including food, .
