Abstract

In this study, determination of liver lipase activity of mature and immature Oncorhynchus mykiss has been purposed. Liver lipase (E.C 3.1.1.3) purification process from mature and immature O. mykiss consisted of three steps: Preparation of homogenate, ammonium sulfate precipitation, Diethylamino ethyl (DEAE) cellulose ion exchange chromatography. Through the purification procedure, liver lipase enzyme of mature fish was purified with a yield of 0.037± 0.06% and a purification coefficient of 2.65±1.94, having the spesific activity of 2.23±1.59 µmol/mg protein. From immature fish, the enzyme was purified with a yield of 3.24±0.51% and a purification coefficient of 15.50±1.13, having the spesific activity of 1.86±0.14 µmol/mg protein.

Özet

Bu çalışmada, ergin ve ergin olmayan Oncorhynchus mykiss’ in karaciğer lipaz (E.C 3.1.1.3) enzimi aktivitesinin belirlenmesi amaçlanmıştır. Ergin ve ergin olmayan O. mykiss karaciğer lipazını saflaştırma işlemleri 3 adımdan oluşmuştur: Homojenatın hazırlanması, amonyum sülfat çöktürmesi, Diethylamino ethyl (DEAE) selülozik iyon değişim kromatografisi. Saflaştırma işlemleri boyunca, ergin balıkların karaciğerinden elde edilen lipaz enziminin spesifik aktivitesi 2.23±1.59 µmol/mg protein, verimi %0.037 ve saflaştırma katsayısı 2.65±1.94 olarak belirlenmiştir. Ergin olmayan balıklarda ise spesifik aktivite 1.86±0.14 µmol/mg protein, verim %3.24±0.51 ve saflaştırma katsayısı 15.50±1.13 bulunmuştur.
