Fibrinolytic enzymes constitute one of the most important groups of industrial enzymes Aspergillus japonicum KSS 05 strain were used for fibrinolytic enzyme production. The potential strain were kept for mutational studies. UV radiation is used as mutagenic agent. The mutant obtained Aspergillus japonicum KSS 05 mu were used for screening of fibrinolytic enzyme production by plate assay and it showed 6 mm diameter clear zone around the colony. Screened mutated strain was employed for the production of fibrinolytic enzyme through submerged fermentation and it showed 252 IU after 72 hr of fermentation. It showed better results compared with Aspergillus japonicum KSS 05 parent strain. | Effect of mutational studies on biosynthesis of fibrinolytic enzyme from Aspergillus japonicum
