ABSTRACT
Objective A strain with high alginase activity was screened and isolated by decomposing sodium alginate from the decaying parts of brown alga Laminaria japonica and Undaria pinnatifida,in order to produce alginase.Methods The strain s4 with high alginase activity was chosen by filtration.The alginase producing media was optimized and the alginase was produced and its characterization was investigated.Results The optimum fermentation conditions for alginate lyase producing as follows: media AlgNa 1.2%,NH4Cl 0.9%,NaCl 1.5%,pH=7.5,and temperature 25℃.Conclusion The alginase produced by strain s4 showed high alginase activity and good stability.
