Enhancement of Monacolin K Production by Intergeneric Hybridization between Monascus purpureus (Arg-) and Monascus ruber (Thi-, Met-) Auxotrophs

Production of Angkak Through Co-Culture of Monascus Purpureus and MONASCUS RUBER

Angkak (red mold rice, red yeast rice, Chinese red rice) is a traditional Chinese medicine produced by solid-state fermentation of cooked non-glutinous rice with Monascus species. The secondary metabolite of Monascus species, monacolin K /lovastatin, has been proven to lower blood lipid levels. In this study, a co-culture of Monascus purpureus MTCC 369 and Monascus ruber MTCC 1880 was used for ...

Biosynthesis of monacolins: conversion of monacolin L to monacolin J by a monooxygenase of Monascus ruber.

The microbial metabolites monacolins J and L are specific inhibitors of 3-hydroxy-3-methylglutaryl CoA reductase, the rate-limiting enzyme in cholesterol synthesis. The producing strain Monascus ruber M 4681 was found to convert exogenously added monacolin L to J. In this hydroxylation reaction 18O2 was incorporated into monacolin L, giving [18O]-monacolin J. The cell-free extracts of M. ruber ...

Review of Angkak Production (Monascus purpureus)

Elevated yield of monacolin K in Monascus purpureus by fungal elicitor and mutagenesis of UV and LiCl.

In China, Monascus spp., a traditional fungus used in fermentation, is used as a natural food additive. Monascus spp. can produce a secondary metabolite, monacolin K namely, which is proven to be a cholesterol-lowering and hypotensive agent. Hence, recently, many researchers have begun focusing on how to increase the production of monacolin K by Monascus purpureus. In the present study, we inve...

Quantification of Lovastatin Produced by Monascus purpureus

Development of a novel method for the quantification of lovastatin is an interesting problem in the analytical field. In the literature, many reports use spectrophotometric method for the quantification of lovastatin. However, the analysis of fermentation broth containing lovastatin appears to be inaccurate using spectrophotometric method. Hence, the estimation of lovastatin produced by Monascu...
