Improvement of Monacolin K and Pigment Production in by 5-Azacytidine.

species are known to produce various secondary metabolites with polyketide structures, including Monacolins, pigments, and citrinin. This study investigates the effects of 5-azacytidine on M1 and RP2. The dry weight, red, yellow, and orange pigment values, and Monacolin K yield of both strains were measured, and their hyphae observed through electron microscopy.

Functional Verification of Transcription Factor comp54181_c0 in Monascus purpureus.

Monacolin K is a valuable secondary metabolite produced after a period of fermentation by Monascus purpureus; however, our current understanding of the regulatory mechanisms of its synthesis remains incomplete. This study conducted functional analysis on the key transcription factor, comp54181_c0, that is involved in the synthesis of monacolin K in Monascus. Mutant strains with either knockout or overexpression of comp54181_c0 were constructed using CRISPR/Cas9.

Mutation Breeding of to Produce a High Yield of Orange Pigment and Low Citrinin Content Using the ARTP Method.

is a filamentous fungus with a long history of application in China, which can produce a variety of secondary metabolites, including Monascus red pigments, orange pigments, yellow pigments, and citrinin. There is widespread attention being paid to natural pigments because of their safety. Among the many natural pigments, orange pigment has a wide range of applications because of its unique color, but current production levels in the orange pigment industry are limited to a certain extent due to the insufficiently wide range of sources and low production.

Occurrence, Risk Implications, Prevention and Control of CIT in Cheese: A Review.

is a filamentous fungus that has been used in the food and pharmaceutical industries. When used as an auxiliary fermenting agent in the manufacturing of cheese, cheese is obtained. Citrinin (CIT) is a well-known hepatorenal toxin produced by that can harm the kidneys structurally and functionally and is frequently found in foods.

Effect of polysaccharide on immunomodulatory activity in mice.

polysaccharides (MCPs) have been reported to exert beneficial roles, such as disease healing, in medicine and pharmacy. However, little is known about their effects on immunomodulation The present study aimed to explore the possible effects of polysaccharide (MCP) on the immunomodulatory activity of mice lymphocytes. To this aim, male BALB/c mice aged 6-8 weeks were assigned to the following six experimental groups: i) Normal (NG); ii) model (MG); iii) positive (PG); iv) MCP low-dose (MLG); v) MCP medium-dose (MMG); and vi) MCP high-dose (MHG).
