Biological activities of oligoketide pigments of Monascus purpureus
Food Additives and Contaminants, 1999Rubropunctatin (1), monascorubrin (2), monascin (3) and ankaflavin (4) were purified from the mycelium of Monascus purpureus by flash chromatography on silica gel or reversed phase. Their embryotoxicity towards chicken embryos decreased in the order 2 > 1 > 3 > 4.

Genetic transformation of Monascus purpureus DSM1379
Biotechnology Letters, 2003Monascus purpureus was transformed into hygromycin B resistance with hygromycin B phosphotransferase (hph) fused to Aspergillus nidulans trpC or a putative Monascus purpureus gpd1 promoter by electroporation. Among five strains, only M. purpureus DSM1397 was a competent recipient.

Polyhydroxylated sterols from Monascus purpureus-fermented rice
Steroids, 2020Using a cell-based cytotoxicity assay, two new polyhydroxylated sterols, 16(S),22(S)-epoxy-3β,5α,6β,20(R),23(R),25-hexahydroxy-7-ergostene and 3β,7β,8α,25-tetrahydroxy-5,22E-ergostadiene were isolated from the ethyl acetate portion of the ethanolic extract of Monascus purpureus.

A new ergostane from Monascus purpureus
Chemistry of Natural Compounds, 2013A new ergostane, named 3,16,20,22,23,25-hexahydroxyergostane, was isolated by means of chromatographic techniques from Monascus purpureus Went., which is the main component of xuezhikang capsule, a Chinese traditional patent medicine. In China, it is used to treat hyperlipidemia, atherosclerosis, cancer, and osteoporosis [1].

Effect of Yeast Extract on Growth Kinetics of Monascus purpureus
Applied Biochemistry and Biotechnology, 2001Growth kinetics and red pigment production of Monascus purpureus CCT 3802 was studied. A reproducible inoculum with extremely dispersed hyphae for bioreactor runs was obtained through a two-step cultivation in a shaker. First, the spores were cultivated in a complex medium rendering a suspension of vegetative cells.

Cytotoxic steroids from Monascus purpureus-fermented rice
Steroids, 2011Bioassay-guided fractionation of an EtOH extract of Monascus purpureus-fermented rice led to the isolation of two new steroids (22S, 23R, 24S)-20β,23α,25α-trihydroxy-16,22-epoxy-4,6,8(14)-trienergosta-3-one (1), the first example of a steroid possessing both a conjugated triene ketone system and a fused 4H-furan ring side chain within one molecule, and

Repeated-batch production of pigments by immobilised Monascus purpureus
Journal of Biotechnology, 2000Extracellular pigment production by immobilised Monascus purpureus C322 has been studied in repeated-batch processes using different immobilising carriers such as Ca-alginate, polyurethane sponge, active carbon and pearlite. With Ca-alginate, pigment production was maximum (30.5 UA470 as process mean production, three batches) while the cell leakage ...

Mycologia, 1910
During the year I909, the writer had frequent occasion to examine the molds which are common in silage not properly prepared or cared for. Such moldy silage has in several instances caused the death of farm animals, particularly horses; the symptoms of the disease being those of " forage poisoning" or " equine cerebro-spinal meningitis." Numerous ...

Pigment production by monascus purpureus [PDF]
This work was concerned with the production of natural red pigments from submerged cultures of Monascus purpureus. The effect of three environmental factors on fungal growth and pigment production was elucidated, and techniques which enhance red pigment production were investigated.Recently, due to public interest in "natural" products, increasingly ...

A comparison of conidial and ascospore germination of Monascus purpureus
Transactions of the British Mycological Society, 1978On malt-extract agar, conidia of Monascus purpureus Went germinated more rapidly and more abundantly than ascospores. Generally, one to two germ-tubes were formed by both conidia and ascospores, but up to six were produced by some larger conidia. Spore germination was influenced by the age of spore, spore density, pH, temperature and nutrient.
