As a typical filamentous fungus Rhizopus chinensis CCTCC M201021 was an important functional strain in the brewing industry, which could produce many kinds of enzymes. In our previous studies, Rhizopus chinensis lipase gene (proRCL,GenBank Accession No. EF405962) had been cloned and high-level expressed in pichia pastoris GS115. In this study, the GAP promoter was inserted into the inducible expression vector pPIC9K-proRCL in order to introduce the double-crossover integration of the lipase gene into the ye...
