The invention discloses a red rice yeast bacterial strain culture medium used for increasing yield of Monat Klin, containing the following materials in parts by weight: malt, potato, corn starch, glucose, glycerol, agar, lactic acid, absolute ethyl alcohol, sodium acetate, soy peptone, phosphate, calcium chloride, a folia perillae acutae concentrated solution, functional yeast, multi-bacteria compound enzyme and sterile glacial acetic acid. According to the invention, a mixed thick slurry prepared from malt, potato and agar as main components is induced by glycerol, high-density growth of cells in the thick slurry is promoted by glucose, and then the thick slurry is induced to perform self protein expression by glycerol, so as to further promote cell growth, increase the protein expressionquantity, and increase the activity of red rice yeast in the culture medium in culture of a red rice yeast bacterial strain, thus effectively promoting metabolism of Monat Klin K, and increasing theyield of Monat Klin K.
