Astaxanthin is a red-colored carotenoid, used as food and feed additive. Astaxanthin is mainly produced by chemical synthesis, however, the process is expensive and synthetic astaxanthin is not approved for human consumption. In this study, we engineered the oleaginous yeast Yarrowia lipolytica for de novo production of astaxanthin by fermentation. First, we screened 12 different Y. lipolytica isolates for β-carotene production by introducing two genes for β-carotene biosynthesis: bi-functional phytoene synthase/lycopene cyclase ( crtYB ) and phytoene desaturase ( crtI ) from the red yeast Xanthophyllomyces dendrorhous ...

Hyperlipidemia is a major risk factor for cardiovascular morbidity and mortality. Treatment strategies include both lifestyle modification and pharmacological therapy. Statins are among the most effective agents to achieve optimal LDL-cholesterol levels, but, not infrequently, patients suffer from myalgia or other side effects. The proven or perceived intolerance to statins requires, therefore, alternative lipid-lowering strategies. In recent years, nutraceuticals have become extensively accepted, and a growing number of molecules with hypothetical cholesterol-lowering activity have been proposed, sometimes with no scientific evidence and/or no methodological accuracy, based only on the belief that these agents are "natural" and do not show side effects...

The new amylolytic oleaginous red yeast, Sporidiobolus pararoseus KX709872, produced both α-amylase (540 ± 0.09 mU/mL) and amyloglucosidase (23 ± 0.00 mU/mL) and showed good ability to directly convert rice residue from canteen waste to biomass and lipids. Effects of medium composition and cultivation conditions on growth and lipid accumulation for strain KX709872 were investigated under shaking-flask and up-scaling levels. At C:N ratio of 25:1, pH 5.45, 22.36°C, and 199.40 rpm for 7 days, volumetric production of biomass and lipids, lipid content, and lipid productivity reached 17...

The extracts of red yeast rice represent a nutraceutical with proven cholesterol lowering effect. Its efficacy is proportional to the concentration on monacolin K in the extract that could reach the amount of 10 mg per daily dose. The daily assumption of monacolin K could then reduce LDL-cholesterol plasma levels by 15-25% in 6-8 weeks. The LDL-cholesterol reduction is associated with a proportional reduction in total cholesterolemia, non-HDL cholesterolemia, plasma apolipoprotein B, high-sensitivity C-reactive protein, and matrix metalloproteinases 2 and 9...

The single cell oil (SCO) production by the mono and mixed culture of microalgae Chlorella pyrenoidosa and red yeast Rhodotorula glutinis was investigated using non-detoxified cassava bagasse hydrolysate (CBH) as carbon source. The results suggested that the two strains were able to tolerate and even degrade some byproducts presented in the CBH, and the mixed culture approach enhanced the degradation of certain byproducts. Biomass (20.37 ± 0.38 g/L) and lipid yield (10.42 ± 1.21 g/L) of the mixed culture achieved in the batch culture were significantly higher than that of the mono-cultures (p < 0...

The red yeast Xanthophyllomyces dendrorhous is an established platform for the synthesis of carotenoids. It was used for the generation of novel multi oxygenated carotenoid structures. This was achieved by a combinatorial approach starting with the selection of a β-carotene accumulating mutant, stepwise pathway engineering by integration of three microbial genes into the genome and finally the chemical reduction of the resulting 4,4'-diketo-nostoxanthin (2,3,2',3'-tetrahydroxy-4,4'-diketo-β-carotene) and 4-keto-nostoxanthin (2,3,2',3'-tetrahydroxy-4-monoketo-β-carotene)...

BACKGROUND: Berberine, an alkaloid with both glucose- and cholesterol-lowering action, is also characterized by an anti-diarrheal effect. Consequently, berberine-based therapies are recommended for diabetic patients with irritable bowel syndrome (IBS) or gut discomfort caused by metformin. AIM: As the anti-glycemic and cholesterol-lowering action of berberine is improved by co-administration with P-glycoprotein inhibitors and naturally derived statins, we have analyzed the effect of the food supplement Berberol®K (hereafter referred to as BSM) containing, berberine, silymarin, and a highly standardized red yeast rice containing monacolins K and KA in the ratio 1:1 but no secondary monacolins, dehydromonacolins, or citrinin (Monakopure™-K20)...

Specific dietary strategies are the mainstay of management in most cases of dyslipidaemia, prior to or simultaneously with the initiation of a lipid-lowering agent. The exact approach differs according to the type of dyslipidaemia. In particular, a reduction in carbohydrates (mainly foods with a high glycaemic index) and their substitution with mono- and polyunsaturated fatty acids is the main strategy in patients with high levels of triglycerides (Tg) and/or low levels of high-density lipoprotein cholesterol (HDL-c)...

BACKGROUND: Statin-associated muscle symptoms are reported by 10% to 29% of patients in clinical practice and are a major determinant of statin nonadherence, discontinuation, and switching. Little is known about what advice patients receive from their providers when dealing with these symptoms. OBJECTIVE: The objective of the study was to assess patient's reports of provider advice when experiencing new or worsened muscle symptoms while taking a statin. METHODS: Data were analyzed from the Understanding Statin Use in America and Gaps in Education survey, a self-administered internet-based survey of 10,138 adults with a reported history of high cholesterol and statin use...

Xuezhikang (XZK), an extract of red yeast rice, is a traditional Chinese medicine widely used for the treatment of cardiovascular diseases in China and other countries. However, whether XZK treatment can improve atherosclerotic plaque stability is not fully understood. Based on our previously developed mouse model of spontaneous vulnerable plaque formation and rupture in carotid arteries in ApoE-/- mice. We showed that low-dose (600 mg/kg/d) XZK improved plaque stability without decreasing plaque area, whereas high-dose (1200 mg/kg/d) XZK dramatically inhibited vulnerable plaque progression accompanied by decreased plaque area...

Bioconversion of biodiesel-derived crude glycerol into carotenoids and lipids was investigated by a microbial conversion of an oleaginous red yeast Sporidiobolus pararoseus KM281507. The methanol content in crude glycerol (0.5% w/v) did not show a significant effect on biomass production by strain KM281507. However, demethanolized crude glycerol significantly supported the production of biomass (8.64 ± 0.13 g/L), lipids (2.92 ± 0.03 g/L), β-carotene (15.76 ± 0.85 mg/L) and total carotenoids (33...

BACKGROUND: Phytosterols and red yeast rice are largely studied cholesterol-lowering nutraceuticals, respectively inhibiting the bowel absorption and liver synthesis of cholesterol. Our aim was to test the effect on lipid profile of phytosterols, red yeast rice and their association. METHODS: We performed a three parallel arms, double blind, clinical trial randomizing 90 moderately hypercholesterolemic subjects to treatment with phytosterols 800 mg (group 1), red yeast rice standardized to contain 5 mg monacolins from Monascus purpureus (group 2), or both combined nutraceuticals (group 3)...

Xuezhikang (XZK), an extract of Chinese red yeast rice, is recommended as an optimal choice for patients with coronary heart disease (CHD) with markedly elevated triglyceride (TG) levels. This study was designed to compare the hypotriglyceridemic effects between XZK and simvastatin. The role of apolipoprotein A5 (apoA5), a key regulator of TG metabolism and a target gene of peroxisome proliferator-activated receptor α (PPARα), was to be identified in XZK-related hypotriglyceridemic actions. For these goals, hypertriglyceridemia of rats was induced by a high-fructose diet...

OBJECTIVE: To observe the effects of red yeast rice (RYR) on blood lipid levels, aortic atherosclerosis (AS), and plaque stability in apolipoprotein E gene knockout (ApoE-/-) mice. METHODS: Twenty-four ApoE-/- mice were fed with a high-fat diet starting from 6 weeks of age. Mice were randomized into three groups (n = 8 in each group): model group (ApoE-/- group), RYR group (ApoE-/- + RYR group), and simvastatin group (ApoE-/- + simvastatin group). Eight 6-week-old C57BL/6 mice were assigned as the control group and fed with a basic diet...

PURPOSE OF REVIEW: Reduction in circulating cholesterol is an important step in lowering cardiovascular risk. Although statins are the most frequently prescribed cholesterol-lowering medication, there remains a significant portion of patients who require alternative treatment options. Nutraceuticals are increasingly popular as cholesterol-lowering agents. Despite the lack of long-term trials evaluating their use on cardiovascular endpoints and mortality, several studies have demonstrated their potential cholesterol-lowering effects...

Here we tested the bioconversion of biodiesel-derived crude glycerol by the oleaginous red yeast Sporidiobolus pararoseus KM281507 in two bioreactors types (stirred-tank and airlift). High production yields (biomass, 10.62 ± 0.21 g/L; lipids, 3.26 ± 0.13 g/L; β-carotene, 30.64 ± 0.05 mg/L; total carotenoids, 46.59 ± 0.07 mg/L) were achieved in a 3.0 L airlift bioreactor under uncontrolled pH regimes (initial pH 5.63). Under optimized conditions (6.0 vvm aeration rate; 60 ± 5% constant dissolved oxygen [DO] maintained by flushing pure oxygen [O2] into the vessel; 10,000 Lux light irradiation) volumetric production in the airlift bioreactor was further increased (biomass, 19...

Low-density lipoprotein cholesterol (LDL-C) reduction is associated with a significant decrease in mortality, and statins represent the most effective drugs to achieve this. However, side effects of statins are very common and may lead to treatment discontinuation. Nutraceuticals are a combination of natural components that have shown efficacy in lowering LDL-C concentration when used alone or in association with other agents in patients who are intolerant to high-dose statins. Our aim was to compare the efficacy and tolerability of low-dose statin (LDS) therapy versus combined therapy of LDS plus a nutraceutical combination containing red yeast rice, policosanol, berberine, folic acid, coenzyme Q10 and astaxanthin (Armolipid Plus) in high-risk patients...
