Amylases are one of the most important and oldest industrial enzymes. The amylase producer Streptomyces sp. MC 10 strain was isolated from soil samples from Celal Bayar University in Manisa. In this study, the α-amylase from Streptomyces sp. MC10 strain was produced and characterized. The effect of initial pH and temperature, fermentation time and substrate concentration was investigated. The effect of initial pH, fermentation time, incubation temparature and initial substrate concentration was investigated. The highest α-amylase concentration of 3,05 IU was obtained for afermentation of period of 96 h with the initial substrate concentration equivalent to %1 and incubation temperature at 28°C, pH 7.5
Streptomyces sp. MC10 SUŞUNUN ALFA AMİLAZ ÜRETİM KABİLİYETİNİN BELİRLENMESİ
Amilazlar en önemli endüstriyel enzimlerden biridir. Amilaz üreticisi olan Streptomyces MC10 suşu Manisa Celal Bayar Üniversitesinden alınan toprak örneklerinden izole edilmiştir. Bu çalışmada Streptomyces MC10 suşundan α-amilaz üretimi ve karakterizasyonu gerçekleştirilmiştir. Bu amaçla suşun besiyerinde üremesi ve α-amilaz üretme yeteneği ve aktivite gösterdiği optimum sıcaklık, pH, inkübasyon süresi ve substrat konsantrasyon değerleri saptanmıştır. Amilaz üretimi için fermentasyon şartları optimize edilmiştir. Optimum fermentasyon şartları üretim süresi 4 gün, substrat konsantrasyonu %1, pH 7.5 ve üretim sıcaklığı 28°C olarak saptanmıştır.
