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

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.

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 ...

Effect of Amino Acids on Red Pigments and Citrinin Production in Monascus ruber

Journal of Food Science, 2012
ABSTRACT:  Amino acids were used as sole nitrogen sources to examine their effects on the production of water‐soluble red pigments and citrinin by Monascus ruber ATCC 96218 cultivated on chemically defined media.

Conversion of a Monascus ruber esterase into a lipase by disrupting a salt bridge

Journal of Molecular Catalysis B: Enzymatic, 2016
Abstract Cold-active lipases have emerged as an important class of biocatalysts for chemical and food industries due to their high efficiency at low temperature and long-chain substrate preference. In an effort to explore the feasibility of converting a cold-active esterase from Monascus ruber (Lip10) into a cold-active lipase, an Y264F variant in ...

A fedbatch strategy for optimal red pigment production by monascus ruber

Bioprocess Engineering, 1995
According to the measurement of the pigment production and some material balance treatments, the monosodium glutamate (MSG), which represents a main substrate involved in the production of red pigment by Monascus ruber, is recovered on-line. Fedbatch operation then represents an alternative for increasing the production of pigment. A nonlinear quotient

Sugarcane bagasse hydrolysate as a potential feedstock for red pigment production by Monascus ruber

Food Chemistry, 2018
Sugarcane bagasse (SCB) hydrolysate could be an interesting source for red pigment production by Monascus ruber Tieghem IOC 2225. The influence of different wavelength of light-emitting diode (LED) at 250 μmol.m-2.s-1 of photon flux density on red pigment production by M. ruber in glucose-based medium was evaluated.
