Description

technical field

[0001] The present invention relates to promoters and their use. Background technique

[0002] In Asian countries, Monascus has long been used as a food additive. The grain fermented by Monascus is bright red to purple, and retains the original shape of rice. In addition, Monascus ferment products are also believed to have health-promoting properties. The application of Monascus in rice wine production is due to its high amount of α-amylase, which can promote the conversion of starch into glucose. Current studies have confirmed the medical effects of Monascus fermented products such as Monacolin K. Moreover, the preservation effect of the fermented product of Monascus has also been proved by experiments.

[0003] The main research focus in this field is the gene product or cultivation and production methods of Monascus, however, the research on Monascus sequence tag (EST) gene bank is in the ascendant, and the sequence tag of Monascus may provide more inf...
