Abstract

Background: Pectinases are one of the upcoming enzymesin food processing industries and they hydrolyze pectinsubstances.Objectives: This study was done to examine the productionof pectinase by Piriformospora indica in submergedfermentation (SmF) along with growth parameters.Materials and methods: The fungus P. indica was culturedon Kafer medium supplemented with pectin for 0–12 daysand fungus growth, number of spores, total proteincontent, and pectinase activity were investigated.Results: Firstly, pectinase secretion by P. indica was confirmedby cup-plate assay. The maximum dry cell weight(10.21 g/L), growth yield (0.65 g/g), specific growth rate(0.56 day−1) and pectinase activity (10.47 U/mL) on pectincontaining medium (P+) were achieved after 6 day ofculture. In the case of pectin free medium (P−) all the parameterswere less than P+ medium. The pectinase productionby P. indica on P+ was 2.7 times higher than P−. Theoptimum pH and temperature for maximum polygalacturonaseactivity were 5 and 50°C, respectively.Conclusions: For the first time, the work confirmed pectinasesecretion by P. indica fungus and it could be a goodsource for pectinase production. Moreover, optimum pH 5,make it a potential candidate for future application in fruitjuice industries.

Özet

Giriş: Pektinazlar, gıda işleme endüstrilerindeki önemli enzimlerden biridir ve pektini hidrolize ederler. Amaç: Bu çalışma, Piriformospora indica tarafından SmF‘de pektinaz üretiminin büyüme parametreleri ile birlikte incelenmesini amaçlamaktadır. Metod: Piriformospora indica mantarı, Kafer ortamında pektin ile 0–12 gün süreyle kültür edildi ve mantar gelişimi, spor sayısı, toplam protein içeriği ve pektinaz aktivitesi araştırıldı. Bulgular: Pektin içeren ortamda (P+) 6 günlük kültür sonrası, maksimum kuru hücre ağırlığı (10.21 g/L), büyüme verimi (0.65 g/g), spesifik büyüme oranı (0.56 day−1) ve pektinaz aktivitesi (10.47 U/mL) olarak tespit edildi. Pektin içermeyen ortamda (P−) tüm parametreler P+ ortamından daha düşüktü. Piriformospora indica‘nın P+ ortamında pektinaz üretimi, P− ortamından 2.7 kat daha yüksekti. Maksimum poligalakturonaz aktivitesi için optimum pH ve sıcaklık sırasıyla 5 ve 50°C olarak bulundu. Sonuç: İlk kez, P. indica mantarının pektinaz sekresyonunu teyit edildi ve pektinaz üretimi için iyi bir kaynak olabileceği ortaya kondu. Ayrıca, elde edilen enzimin optimum pH’sının 5 olması, meyve suyu endüstrisinde potansiyel bir aday olması için önem taşımaktadır.
