1. utilize tea fungus and raffinose to produce a method for Nano bacteria cellulose, comprising:

  • (1) get cotton dregs, be soaked in the aqueous solution containing ethanol, soak 1 ~ 3 hour at 50 ~ 80 DEG C, filter or centrifugally obtain extracting solution, repeatedly, merge;

    (2) by extracting solution or raffinose that extracting solution evaporate to dryness is obtained soluble in water, add nitrogenous source and be mixed with fermention medium, pH is adjusted to 4.0 ~ 6.0 sterilizings;

    By the seed liquor of tea fungus access fermention medium, static gas wave refrigerator, dynamic cultivation or stir culture at 20 ~ 30 DEG C, through 3 ~ 20 days obtained Nano bacteria celluloses.
