Biopigments from Monascus: Strains Selection, Citrinin Production and Color Stability
Fungi form the genus Monascus are a promising source for natural color additives. However, before effectively applying Monascus to foods, it is important to select strains which produce large amounts of biopigments but little or no citrinin, a mycotoxin usually also produced by these fungi. Also, color stability of these pigments should be properly investigated. In order to compare Monascus str...
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 کاملEFFECT OF DISSOLVED OXYGEN CONCENTRATION ON RED PIGMENT AND CITRININ PRODUCTION BY Monascus purpureus ATCC 36928
The present study investigated the effects of agitation speed, N (200, 500, 600 or 700 rpm), and dissolved oxygen concentration, C (120, >70, 70, 60, 10 or 10%), on red pigment and citrinin production by Monascus purpureus ATCC 36928, cultivated in liquid medium by a batch process. The gas flow rate was the same for all runs with C controlled by means of the incoming gas composition control (ai...
متن کاملPigments and citrinin biosynthesis by fungi belonging to genus Monascus.
Citrinin is a mycotoxin, which is produced by fungi belonging to the genus Monascus, known in biotechnology as producers of azaphilone pigments. The relation between biosynthesis of these secondary metabolites was investigated in different species of the genus Monascus in batch-culture at the following cultivation conditions: T = 28 degrees C, agitation 220 rpm, and a medium, which induce citri...
متن کاملMedium-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...
