Abstract
This study investigated the production performance, carcass characteristics, and meat quality attributes of broilers fed with different doses of Monascus-fermented Moringa oleifera leaves. A total of 400 one-day-old unsexed Greenleg partridge broilers were randomly divided into 4 dietary which were fed a basal diet supplemented with 0, 5% Monascus-fermented Moringa oleifera leaves, 10% Monascus-fermented Moringa oleifera leaves, and 10% Moringa oleifera leaves, respectively. Each group had 5 replicates of twenty birds each. The whole trial lasted for 63 d. The results indicated that a high dose of Moringa oleifera leaves supplement in broiler diet reduced the production performance, carcass characteristics, and meat quality attributes (P < 0.05). While the addition of the same dose of Monascus-fermented Moringa oleifera leaves reversed this adverse effect, and the 5% Monascus-fermented Moringa oleifer leaves supplement was found to be more effective (P < 0.05). In addition, Monascus-fermented Moringa oleifera leaves improved the concentration of amino acids and polyunsaturated fatty acids in the meat, which could be beneficial for human health. We conclude that, a 5% Monascus-fermented Moringa oleifera leaves supplement in the diet is beneficial in terms of improved growth performance and the functional attributes of meat than sole Moringa oleifera leaves supplement.

Abstract
Bidirectional fermentation is a technology that utilizes fungi to ferment medicinal edible substrates, with synergistic and complementary advantages. In this work, a fermentation strategy was established to produce a high yield of γ-aminobutyric acid (GABA) and Monascus pigments (MPs) using Monascus and mulberry leaves (MLs). Firstly, the basic fermentation parameters were determined using single-factor experiments, followed by Plackett-Burman (PB) experimental design to identify MLs, glucose, peptone, and temperature as significant influencing factors. The fermentation parameters were optimized using an artificial neural network (ANN). Finally, the effects of bidirectional fermentation of MLs and Monascus were investigated by bioactivity analysis, microstructure observation, and RT-qPCR. The outcomes showed that the bidirectional fermentation significantly increased the bioactive content and promoted the secondary metabolism of Monascus. The established fermentation conditions were 44.2 g/L of MLs, 57 g/L of glucose, 15 g/L of peptone, 1 g/L of MgSO4, 2 g/L of KH2PO4, 8% (v/v) of inoculum, 180 rpm, initial pH 6, 32 °C and 8 days. The content of GABA reached 13.95 g/L and the color value of MPs reached 408.07 U/mL. This study demonstrated the feasibility of bidirectional fermentation of MLs and Monascus, providing a new idea for the application of MLs and Monascus.

Abstract
Hypercholesterolemia represents a serious public health problem as it significantly increases the risk of developing cardiovascular diseases. Monacolin K (MK) in red yeast rice is an active compound that can effectively lower plasma cholesterol. To enhance the yield of MK in solid state fermentation of Monascus purpureus HNU01, the effects of different variables were systematically examined in single-factor experiments. The optimal conditions for the production of red yeast rice rich in MK were as follows: initial pH value 5.5, initial moisture content 40% w/w, glucose 50 g L-1, peptone 20 g L-1, MgSO4 0.5 g L-1, KH2PO4 1 g L-1, variable temperature fermentation (30 °C for the first 3 days and then 24 °C for 15 days), total fermentation time of 18 days, and additional water added at day 4 at 10% w/w. Under the above optimized conditions, the MK content of red yeast rice produced by fermentation was 9.5 mg g-1. No citrinin was detected in any of the batches of fermentation products. The results will be useful for the large-scale production of high-quality red yeast rice with health benefits for consumers.

Abstract
This study investigated the effect of ultrasound-assisted hydrogen peroxide (H2O2) pretreatment on sugar cane bagasse (SCB) followed by Monascus purpureus TISTR 3003 cultivation for lovastatin production under solid-state fermentation (SSF). Optimization of the pretreatment conditions was investigated using a response surface methodology (RSM). Within the range of the selected operating conditions, the optimized values of H2O2 concentration, amplitude, SCB dosage, and sonication time were found to be 2.74%, 83.22 μm, 2.84% and 52.29 min, respectively. The R 2 value of 0.9749 indicated that the fitted model is in good agreement with the predicted and actual lovastatin production. On the basis of the optimum conditions, the lovastatin production was 2347.10 ± 17.19 μg/g, which is 2.4 times higher than that under untreated conditions. Scanning electron microscopy (SEM) analysis explored the surface structure of the untreated SCB, which showed a compact rigid structure. In contrast, treated SCB had a rough surface structure and cracks as a result of the pretreatment.

Abstract
In this study, a high monacolin K yield was achieved through solid-state fermentation of Ginkgo biloba seeds. Monascus purpureus suspension made from red yeast rice was used as spore inoculum. Fermentation conditions in solid-state fermentation were optimized using response surface methodology, and the optimal conditions for the maximum monacolin K yield (17.71 ± 1.57 mg/g) were 0.22% ammonium sulfate, 0.34% ammonium chloride, 0.05% magnesium sulfate, fermentation time of 12 days, inoculation volume of 11%, and temperature of 27 °C. The total phenolic content of Monascus-fermented ginkgo seeds attained 9.67 mg GAE/g, 4.88-fold higher than that of unfermented ginkgo seeds. The scavenging abilities of DPPH and ABTS free radicals increased to 9.79 mg TE/g and 13.92 mg TE/g, respectively. These findings highlight the importance of investigating the optimal fermentation conditions for maximum monacolin K yield and the utilization value of ginkgo seed as fermentation substrate for higher bioactivities.

Abstract
Monacolin K (MK) is a secondary metabolite of the Monascus species that can inhibit cholesterol synthesis. Functional red mold rice (FRMR) is the fermentation product of Monascus spp., which is rich in MK. FRMR is usually employed to regulate serum cholesterol, especially for hypercholesterolemic patients who refuse statins or face statin intolerance. The present perspective summarized the bioactive components of FRMR and their functions. Subsequently, efficient strategies for FRMR production, future challenges of FRMR application, and possible directions were proposed. This perspective helps to understand the present situation and developmental prospects of FRMR.

Abstract
AbstractIn Asia, Monascus has been used in food fermentation for nearly a thousand years. It has attracted increasing attention in recent years due to its ability to produce a variety of important active substances such as monacolin K (MK) and pigments. MK is an effective drug widely used for lowering human blood cholesterol that functions by inhibiting the rate-limiting enzyme in cholesterol biosynthesis. Monascus strains, fermentation methods and fermentation conditions have significant effects on MK yield, and much research has been undertaken to obtain higher MK yields. In this paper, the research progress of Monascus strain breeding for high MK yield, medium optimization for MK production during Monascus fermentation, and optimization of fermentation process conditions are fully reviewed. This provides reference for future research on Monascus fermentation and industrial production for high-yield MK production.

Abstract
Red Yeast Rice, produced by solid state fermentation of Monascus species on rice, is a traditional food additive and traditional Chinese medicine. With the introduction of modern microbiology and biotechnology to the traditional edible filamentous fungi Monascus species, it has been revealed that the production of red colorant by fermentation of Monascus species involves the biosynthesis of orange Monascus pigments and further chemical modification of orange Monascus pigments into the corresponding derivates with various amine residues. Further study indicates that non-Monascus species also produce Monascus pigments as well as Monascus-like pigments. Based on the chemical modification of orange Monascus pigments, the diversification of native Monascus pigments, including commercial food additives of Red Monascus Pigments® and Yellow Monascus Pigments® in Chinese market, was reviewed. Furthermore, Monascus pigments as well as their derivates as enzyme inhibitors for anti-obesity, hyperlipidemia, and hyperglycemia was also summarized.

Abstract
The biosynthesis of microbial secondary metabolites is induced by a wide range of environmental stresses. In this study, submerged fermentation of Monascus yellow pigments by Monascus ruber CGMCC 10910 under high glucose stress was investigated. The increase of lipid content was the major contributor to the increase of dry cell weight (DCW), and the lipid-free DCW was only slightly changed under high glucose stress, which benefited the accumulation of intracellular hydrophobic pigments. The fatty acid composition analysis in Monascus cell membranes showed that high glucose stress significantly increased the ratio of unsaturated/saturated fatty acid and the index of unsaturated fatty acid (IUFA) value, which would improve the fluidity and permeability of the cell membrane. As a consequence, high glucose stress increased extracellular yellow pigments production by enhancing secretion and trans-membrane conversion of intracellular pigments to the broth. The total yield of extracellular and intracellular yellow pigments per unit of lipid-free DCW increased by 94.86 and 26.31% under high glucose stress compared to conventional fermentation, respectively. A real-time quantitative PCR analysis revealed that the expression of the pigment biosynthetic gene cluster was up-regulated under high glucose stress. The gene mppE, which is associated with yellow pigment biosynthesis, was significantly up-regulated. These results indicated that high glucose stress can shift the Monascus pigment biosynthesis pathway to accumulate yellow pigments and lead to a high yield of both extracellular and intracellular yellow pigments. These findings have potential application in commercial Monascus yellow pigment production.

Abstract
In this study, various grains such as rice, millet, corn, barley and wheat were used as raw materials for monacolin K production by solid-state fermentation of Monascus ruber. Among these substrates, millet was found to be the best one for monacolin K production, by which the yield reached 7.12 mg/g. For enhanced monacolin K production, the effects of fermentation time, charge amount, initial moisture content and inoculum volume were systematically investigated in the solid-state fermentation of M. ruber. Moreover, complementary carbon source and nitrogen source were added for further improving the production of monacolin K. Results showed that the maximum production of monacolin K (19.81 mg/g) could be obtained at the optimal conditions. Compared with the traditional red mold rice, using millet as substrate is promising for high production of monacolin K in the solid-state fermentation of M. ruber.

Abstract
Monacolin K (MK) produced by Monascus spp. is mostly used to regulate cholesterol level, while it can be contaminated by citrinin, a mycotoxin yielded by some Monascus strains. To develop production of citrinin-free MK, an M. sp. MS-1 strain, identified as M. pilosus by morphologies and internal transcribed spacer sequences analysis, was isolated from red fermented rice. After 14 days of fermentation, yields of citrinin-free MK could be up to 0.58 mg/mL and 16.45 mg/g in liquid- and solidstate fermentation products under optimal conditions, respectively. Further determination revealed that no citrinin biosynthesis related genes such as ctnA, pksCT, ctnE, and ctnR were detected. Thus, HPLC combined with citrinin-related gene analyses can be used for rapid screening of non-citrinin production Monascus strains.

Abstract
Red yeast rice (RYR), the fermentation product of mold Monascus purpureus has been an integral part of Oriental food and traditional Chinese medicine, long before the discovery of their medicinal roles. With the identification of bioactive components as polyketide pigments (statins), and unsaturated fatty acids, RYR has gained a nutraceutical status. Hypercholesterolemic effect of this fermented compound has been validated and monacolin K has been recognized as the pivotal component in cholesterol alleviation. Functional similarity with commercial drug lovastatin sans the side effects has catapulted its popularity in other parts of the world as well. Apart from the hypotensive role, ameliorative benefits of RYR as anti-inflammatory, antidiabetic, anticancer and osteogenic agent have emerged, fueling intense research on it. Mechanistic studies have revealed their interaction with functional agents like coenzyme Q10, astaxanthin, vitamin D, folic acid, policosanol, and berberine. On the other hand, concurrence of mycotoxin citrinin and variable content of statin has marred its integration in mainstream medication. In this disputable scenario, evaluation of the scopes and lacunae to overcome seems to contribute to an eminent area of healthcare. Red yeast rice (RYR), the rice-based fermentation product of mold Monascus purpureus is a functional food. Its bioactive component monacolin K acts like synthetic drug lovastatin, without the severe side effects of the latter. RYR has been validated to lower cholesterol, control high blood pressure; confer anti-flammation, hypoglycaemic, anticancer and osteogenic properties. However, dose inconsistency and co-occurrence of toxin citrinin hampers its dietary supplementation prospect. Further research might facilitate development of RYR as a nutraceutical.

Efficient gene targeting in ligase IV-deficient Monascus ruber M7 by perturbing the non-homologous end joining pathway. Fungal Biol 2014; 118:846-54.

Abstract
Inactivating the non-homologous end joining (NHEJ) pathway is a well established method to increase gene replacement frequency (GRF) in filamentous fungi because NHEJ is predominant for the repair of DNA double strand breaks (DSBs), while gene targeting is based on homologous recombination (HR). DNA ligase IV, a component of the NHEJ system, is strictly required for the NHEJ in Saccharomyces cerevisiae and Neurospora crassa. To enhance the GRF in Monascus ruber M7, we deleted the Mrlig4 gene encoding a homolog of N. crassa DNA ligase IV. The obtained mutant (MrΔlig4) showed no apparent defects in vegetative growth, colony phenotype, microscopic morphology, spore yield, and production of Monascus pigments and citrinin compared with the wild-type strain (M. ruber M7). Gene targeting of ku70 and triA genes revealed that GRF in the MrΔlig4 strain increased four-fold compared with that in the wild-type strain, reached 68 % and 85 %, respectively. Thus, the MrΔlig4 strain is a promising host for efficient genetic manipulation. In addition, the MrΔlig4 strain is more sensitive than M. ruber M7 to a DNA-damaging agent, methyl methanesulfonate.
