1. a production method for high conversion organoselenium malt yeasts, is characterized in that comprising the following steps:

  • (1) wheat being placed on concentration is the 20 ~ 22h that soaks seed in the solution of the sodium selenite solution of 200-400mg/L, and makes seed soaking degree reach 42-44%;

    (2) wheat vernalization under appropriate conditions, namely relative humidity is 90 ~ 95%, temperature is 20 ~ 25 DEG C;

    (3) with the sodium selenate solution spraying wheat of 50 ~ 100mg/L, every 10 ~ 30 minutes sprays once;

    (4) calcium sulfate of 0.5 ~ 1% is added in solution automatically to regulate potential of hydrogen;

    (5) young shoot cut to lengthen is at 1 ~ 5cm, after having germinateed, totally obtains rich selenium to wet Fructus Hordei Germinatus with clear water drip washing;

    (6) the above obtained rich selenium Fructus Hordei Germinatus ozone that wets is added microwave disinfection, pulverize pulping, tune pH is 4.5-7.0, makes Fructus Hordei Germinatus rich in selenium substratum slurries.(7) barms of access 22 ~ 30% in obtained Fructus Hordei Germinatus rich in selenium substratum slurries, cultivates 10 ~ 15 hours, obtains first-generation high conversion organoselenium malt yeasts bacterial classification under the condition of 25 ~ 32 DEG C.
