Medium-chain fatty acids affect citrinin production in the filamentous fungus Monascus ruber.
During submerged culture in the presence of glucose and glutamate, the filamentous fungus Monascus ruber produces water-soluble red pigments together with citrinin, a mycotoxin with nephrotoxic and hepatoxic effects on animals. Analysis of the (13)C-pigment molecules from mycelia cultivated with [1-(13)C]-, [2-(13)C]-, or [1, 2-(13)C]acetate by (13)C nuclear magnetic resonance indicated that th...
متن کاملBiosynthetic pathway of citrinin in the filamentous fungus monascus ruber as revealed by 13C nuclear magnetic resonance
Carbon isotope distribution of [13C]citrinin from Monascus ruber incubated with [13C]acetate revealed that the biosynthesis of the toxin originated from a tetraketide, instead of a pentaketide as has been shown for Penicillium and Aspergillus species. The production of polyketide red pigments and citrinin by M. ruber may therefore be regulated at the level of the tetraketide branch point.
متن کاملEffect of media composition on citrinin and bio-pigments production by Monascus ruber
Article history: Received on: 06/12/2016 Accepted on: 19/01/2017 Available online: 20/03/2017 Monascus species are used for production of red bio-pigments, which are used as food coloring agents. However, presence of the mycotoxin citrinin, which is a secondary metabolite produced in conjunction with the red pigments, prevents the use of these pigments in large scale. In the present study, Mona...
متن کاملRepression of secondary metabolite production by exogenous cAMP in Monascus.
The cAMP signal pathway controls various biological functions, including secondary metabolism of filamentous fungi. We found that exogenous cAMP represses the production of lovastatin, red pigments, and citrinin in Monascus. Interestingly, a mutant MK-1 with increased lovastatin and red pigments production was not influenced by cAMP on these productions, indicating that cAMP signaling might be ...
متن کاملProduction of Angkak Through Co-Culture of Monascus Purpureus and MONASCUS RUBER
Angkak (red mold rice, red yeast rice, Chinese red rice) is a traditional Chinese medicine produced by solid-state fermentation of cooked non-glutinous rice with Monascus species. The secondary metabolite of Monascus species, monacolin K /lovastatin, has been proven to lower blood lipid levels. In this study, a co-culture of Monascus purpureus MTCC 369 and Monascus ruber MTCC 1880 was used for ...
