In China, the toxic metabolite potentially existed in Monascus products might be a new concept.With 8 papers published in recent years as references, we have reviewed the research work in Monascus metabolite-citrinin, such as the potential producer strain, the biosynthetic metabolic pathway, the control of its formation in submerged fermentation process.

In China, the toxic metabolite potentially existed in Monascus products might be a new concept.With 8 papers published in recent years as references, we have reviewed the research work in Monascus metabolite-citrinin, such as the potential producer strain, the biosynthetic metabolic pathway, the control of its formation in submerged fermentation process. As the citrinin was considered as a kind of mycotoxin, and it was found in Monascus products manufactured by both solid state and submerged fermentation processes, so we have to pay close attention to this problem. It is necessary to investigate the strains used in factories to see if they produce citrinin, then select the citrinin-free strains as producers; and we have to establish the suitable production process to manufacture citrinin-free Monascus products.

红曲产品中可能存在真菌毒素(mycotoxin)———桔霉素(citrinin)。根据国内外对红曲桔霉素的最新研究成果,介绍了桔霉素的有关性质,如桔霉素的产生菌种(株)、桔霉素的代谢途径、桔霉素的有关理化性质、如何控制桔霉素的产生。作者认为,桔霉素问题的出现,对我国红曲生产及应用领域来说,既是机遇,又是挑战。我国红曲生产行业对红曲桔霉素的问题应引起足够的重视,对生产菌种及红曲的发酵工艺技术要进行系统的考察,以便生产不含桔霉素或桔霉素含量低的红曲产品。

The methods for the determination of citrinin contents in Monascus products were described in this paper. The detecting limit for the standard citrinin solution is 0.2 mg/L when spotting 1ml of standard citrinin onto TLC with the length of 1cm by observing under UV (365 nm) with naked eye. Three types of methods were employed by using different HPLC detectors and the pretreatment of the samples, and two of them were found satisfied in recovery rate, repeatability test and accuracy. The lowest detecting limit...

The methods for the determination of citrinin contents in Monascus products were described in this paper. The detecting limit for the standard citrinin solution is 0.2 mg/L when spotting 1ml of standard citrinin onto TLC with the length of 1cm by observing under UV (365 nm) with naked eye. Three types of methods were employed by using different HPLC detectors and the pretreatment of the samples, and two of them were found satisfied in recovery rate, repeatability test and accuracy. The lowest detecting limit of the citrinin by HPLC with fluorescence detector is 0.6 ng. The lowest detecting concentration of the citrinin solution by using HPLC is 0.2 mg/L. The linear relationship between the contents of the standard citrinin and the peak area is satisfied with the value of R 2 being 0.998.

用16株红曲霉分别接种酵母浸膏蔗糖培养基(YSM)和土豆葡萄糖培养基(PDM),并采用高效液相色谱法(HPLC)检测了培养基中桔霉素的含量,以观察不同培养条件对红曲霉产桔霉素的影响。结果发现,红曲霉于YSM中27℃静置培养14d时,有13株产桔霉素,其含量为2~192mg/L不等;而在PDM中35℃振荡培养8d时,只有4株产桔霉素,其含量在3~21mg/L之间;在两种培养条件下均产桔霉素的有4株,且均为安卡红曲霉。
