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.

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

Suface Features of Monascus ruber van Tieghem Cleistothecia

Botanical Gazette, 1978
Cleistothecial production of Monascus ruber van Tieghem was investigated during delimitation of the antheridium, ascogonium, trichogyne, and ascospore release. Attention was directed to cleistothecial development with formation of branched, sterile, investing hyphae and to the flattening and anastomosis of external cells in the protective wall.

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.

A New Azaphilone Metabolite from the Fungus Monascus ruber

Chemistry of Natural Compounds, 2016
Phytochemical investigation of the 95% EtOH extract of red yeast rice fermented with the fungus Monascus ruber led to the isolation and structural elucidation of one new azaphilone derivative, monascuspurone (1). The structure was defined on the basis of UV, IR, 1D and 2D NMR (1H–1H COSY, DEPT, HSQC, HMBC), as well as HR-ESI-MS analyses, and comparison

Identification of new red pigments produced by Monascus ruber

Dyes and Pigments, 2007
A new monascus red pigment, which was produced in a defined medium with rice and hydrolytic bean powder was identified by IR, UV, NMR and ESI-MS. It was free pigments linked to lysine by amino group, where nitrogen replaced the pyronoid oxygen without hydrophilic side chain.

Kinetic of orange pigment production from Monascus ruber on submerged fermentation

Bioprocess and Biosystems Engineering, 2016
Pigments produced by species of Monascus have been used to coloring rice, meat, sauces, wines and beers in East Asian countries. Monascus can produce orange (precursor), yellow and red pigments. Orange pigments have low solubility in culture media and when react with amino groups they become red and largely soluble.

Proteome analysis reveals global response to deletion of mrflbA in Monascus ruber

Journal of Microbiology, 2018
Monascus spp. are commonly used for a wide variety of applications in the food and pharmaceutical industries. In previous studies, the knock-out of mrflbA (a putative regulator of the G protein α subunit) in M. ruber led to autolysis of the mycelia, decreased pigmentation and lowered mycotoxin production.

Monascus ruber as cell factory for lactic acid production at low pH

Metabolic Engineering, 2017
A Monascus ruber strain was isolated that was able to grow on mineral medium at high sugar concentrations and 175g/l lactic acid at pH 2.8. Its genome and transcriptomes were sequenced and annotated. Genes encoding lactate dehydrogenase (LDH) were introduced to accomplish lactic acid production and two genes encoding pyruvate decarboxylase (PDC) were ...
