MpigE, a gene involved in pigment biosynthesis in Monascus ruber M7

Applied Microbiology and Biotechnology, 2013
Monascus pigments (MPs) have been used as food colorants for several centuries in Asian countries. However, MP biosynthesis pathway is still a controversy, and only few related genes have been reported. In this study, the function of MpigE, a gene involved in MP biosynthesis in Monascus ruber M7, was analyzed.

Deletion of pigR gene in Monascus ruber leads to loss of pigment production

Biotechnology Letters, 2013
Pigments produced by Monascus are traditional food colorants and are widely used as dietary supplements. Since genes involving in pigment biosynthesis have not been reported, we describe the identification of a putative pigment-regulatory gene (pigR) obtained by molecular analysis of an albino strain of Monascus ruber M7.

Acidic conditions induce the accumulation of orange Monascus pigments during liquid-state fermentation of Monascus ruber M7

Applied Microbiology and Biotechnology, 2019
The influence of pH on the biosynthesis of orange Monascus pigments (OMPs) in Monascus ruber M7 was investigated. Under acidic fermentation conditions, pigment mixtures predominantly rich in OMPs were obtained. HPLC analysis revealed the presence of four orange components (O1-O4) and four yellow components (Y1-Y4) in the mixtures, and the dominant ones

Identification and role analysis of an intermediate produced by a polygenic mutant of Monascus pigments cluster in Monascus ruber M7

Applied Microbiology and Biotechnology, 2016
Monascus pigments (Mps) are a group of azaphilonic secondary metabolites produced by Monascus spp. via a polyketide pathway. A mutant deleted an about 30 kb region of Mps gene cluster from Monascus ruber M7 was isolated previously, which produces a high amount of a light yellow pigment.

Inactivation of MrSir2 in Monascus ruber Influenced the Developmental Process and the Production of Monascus Azaphilone Pigments

Applied Biochemistry and Biotechnology, 2022
Monascus species are the producers of Monascus azaphilone pigments (MonAzPs) and lipid-lowering component Monacolin K, which have been widely used as food colorant and health products. In this study, silent information regulator 2 (Sir2) homolog (MrSir2) was characterized, and its impacts on the development and MonAzPs production of Monascus ruber were

Metabolites of Monascus ruber in silages

Journal of Animal Physiology and Animal Nutrition, 2001
A total of 233 silages were examined and found that Monascus ruber was present in 43 samples with counts between 1 × 103 and 9 × 106 colony‐forming units (CFU)/g (mean: 2 × 105 CFU/g). Monacolin KL and the hydroxy acid monacolin KA were detected by liquid chromatography‐mass spectrometry in 45 and 50 of 233 samples at levels ranging from 25–15 600 and ...

Monascus ruber: A new of onychomycosis in the north of Morocco (Tetouan)

Journal de Mycologie Médicale, 2018
We report a case of onychomycosis caused by Monascus ruber from 57-year old women. The diagnosis was based on culture morphological characteristics on Sabouraud's Dextrose agar one with antibacterial (chloramphenicol) and the other with cycloheximide. The identification of specie was confirmed by DNA sequencing.

A New Pyrrole Compound from Monascus ruber

Chemistry of Natural Compounds, 2019
Phytochemical investigation of the fungus Monascus ruber led to the isolation of one new alkaloid derivative, namely ruberpyrrole (1). The structures were established by extensive spectroscopic characterization and the reported data.

Optimal C:N ratio for the production of red pigments by Monascus ruber

World Journal of Microbiology and Biotechnology, 2014
The carbon-to-nitrogen (C:N) ratio in the biomass of microfungi tends to be quite different (e.g. 10-15) compared with the C:N ratio in the red pigments (e.g. >20) of the fungus Monascus ruber. Therefore, determining an optimal C:N ratio in the culture medium for maximizing the production of the pigments is important.
