Purification and characterisation of fibrinolytic enzymes from endophytic fungi and Lignosus rhinocerus

Three enzymes fh3,s13 and lr1 from three different sources showed fibrinolytic activities. two were from endophytic fungal cultures and one from the sclerotium of lignosus rhinocerus mushroom (lr1). fh3,s13 cultures and lr1,the crude extract of the sclerotium were concentrated and purified by ammonium sulphate precipitation,ion-exchange chromatography and gel-filtration. the molecular weights of the fh3,s13 and lr1 purified enzymes were estimated to be approximately 34kda,34kda and 10kda,respectively. maximum fibrinolytic activities were observed for fh3 at ph 7 and 30°c,s13 at ph 8 and 40°c and lr1 at ph 6 and 40°c. in our earlier paper we identified fh3 as fusarium sp. and s13 as penicilium citrinum. © 2016 penerbit utm press. all rights reserved.
