The health-promoting potential of 70% ethanolic extracts of 4 rice varieties fermented with Monascus ruber, Phellinus linteus, Cordyceps sinensis and Agaricus blazei was evaluated mainly focusing on their antioxidative and antimutagenic capacities based on the following parameters: phenolic compound and phytic acid content; inhibitory activity on lipid peroxidation; scavenging activity on DPPH ...

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.

Monascus purpureus is an important medicinal and edible microbial resource. To facilitate biological, biochemical, and molecular research on medicinal components of M. purpureus, we investigated the M. purpureus transcriptome by RNA sequencing (RNA-seq). An RNA-seq library was created using RNA extracted from a mixed sample of M. purpureus expressing different levels of monacolin K output. In t...

We investigated the in vitro inhibitory activity against skin aging-related enzymes and antioxidant activity of Monascus-fermented soybean extracts (MFSEs) obtained by using different solvents. The highest Trolox equivalent (TE) antioxidant capacity (3.13±0.06 mM TE/g) and oxygen radical absorbance capacity (2.79±0.09 mM TE/g) of MFSEs were evaluated for the methanol and 80% ethanol extracts, r...

Hypercholesterolemia is one of the most common chronic diseases in human. Along with chemical therapy traditional medication is used as hypocholesterolemic remedy, however, with unfavorable side effects. Recently, Monascus fermented product (MFP) has become a popular hypocholesterolemic natural supplement. In the present study, the hypocholesterolemic activity of Monascus purpureus FTC5391 ferm...

Four new pyridine derivatives, monasnicotinates A-D (1-4) were isolated from the red yeast rice of Monascus pilosus BCRC 38093. Their structures were elucidated on the basis of physicochemical evidence, in-depth NMR spectroscopic analysis, and high-resolution mass spectrometry. Their inhibitory effects on NO production was also evaluated.

In present study, two species of Hyphomycetes fungi including, Cephaliophora tropica (in soil), and Monascus pilosus (on corn silage) are reported for the first time to Iranian mycobiota. Descriptions of these species have been provided with morphological characteristics and ITS rDNA sequence analyses.  

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 ...

Os pigmentos Monascus, além de possuírem cores atrativas, possuem alto poder corante, entretanto, podem ser instáveis em temperaturas elevadas e pH extremos. Nesse contexto, alguns métodos alternativos vêm surgindo para favorecer sua estabilidade, como a liofilização. Este estudo buscou avaliar o efeito da liofilização na estabilidade frente à temperatura (50 90 ºC) (3 8) dos Monascus purpureus...
