Abstract：

This　study　aimed　to　investigate　the　effect　and　regulatory　mechanism　of　ammonium　chloride　on　the　production　of　Monascus　pigments　and　citrinin　in　Monascus　purpureus　M3103.　The　results　showed　that　the　addition　of　ammonium　chloride　could　significantly　increase　the　yield　of　Monascus　pigments　but　reduce　the　yield　of　citrinin　in　red　rice　as　fermentation　matrix.　In　particular,　the　production　of　Monascus　yellow　pigment　and　orange　pigment　were　significantly　enhanced　by　the　addition　of　ammonium　chloride　through　high　performance　liquid　chromatography-ultraviolet　and　visible　light　(HPLC-UV-Vis)　full　wavelength　scanner.　Using　quantitative　real-time　polymerase　chain　reaction,　the　relative　expression　of　the　key　genes(mppC,　mppD,　mppE,　MpFasA2　and　MpPKS5)　responsible　for　the　production　of　Monascus　pigments　biosynthesis　were　detected　significantly　increased　compared　with　the　control　group.　However,　the　key　genes　(ctnA　and　PksCT)　responsible　for　the　production　of　Monascus　citrinin　biosynthesis　were　detected　significantly　decreased　compared　with　the　control　group.　Therefore,　adding　moderate　amount　of　ammonium　chloride　to　solid-state　fermentation　can　affect　the　absorption　and　metabolism　of　nutrients　by　Monascus　purpureus　M3103.　The　addition　of　ammonium　chloride　is　beneficial　to　promote　the　biosythesis　of　Monascus　pigments,　especially　orange　pigment,　and　inhibit　the　biosynthesis　of　citrinin.　©　2019,　Editorial　Office　of　Journal　of　CIFST.　All　right　reserved.
