Abstract：

A　pectinase-producing　strain-Aspergillus　niger　YQ-13　was　mutagenized　with　UV-LiCl　and　the　mutant　YQY-36　was　obtained.　The　pectinase　activity　of　the　mutant　YQY-36　was　increased　to　67.6　U/mL,　2.44　times　higher　than　that　of　the　original　strain　YQ-13.　Plackett-Burman,　steepest　ascent　and　central　composite　designs　were　employed　to　optimize　the　fermentation　media　of　YQY-36　in　this　study.　The　results　showed　that　the　optimum　medium　contained　(g/L):　orange　peel　42.5,　glucose　5.0,　peptone　28.5,　(NH4)2SO4　15.0,　Na2HPO4·12H2O　1.7,　KH2PO4　1.4,　ZnSO4·7H2O　0.5.　As　a　result,　the　maximum　pectinase　activity　of　strain　YQY-36　was　92.1　U/mL　and　increased　36.2%　after　optimization.　©　2016,　Chinese　Institute　of　Food　Science　and　Technology.　All　right　reserved.
