ABSTRACT:
The invention provides a method of textile printing using microorganisms with less limitation to dyes with less damage on base materials, and with less blurring of color borders. The method is capable of producing a complex, fine pattern; capable of realizing colored discharge printing with brilliant colors; and capable of readily producing an ombre pattern. The invention also provides a microorganism for decolorization of azo-system dye and use in the textile printing method. In accordance with the invention, textile printing is carried out by coating a solution or paste (which may contain a dye) containing a bacterial strain Bacillus OY1-2 of genus Bacillus (Deposit Number: FERM 13118), in a desirable pattern on the cloth dyed with an azo dye (which may include a non-azo dye), subsequently proliferating or acting the bacterial strain while keeping the strain in a wet state, and to entirely or partially metabolize the azo dye to eliminate or decrease the coloring of the azo dye for textile printing. The method may be used, for example, in direct textile printing, white discharge printing, colored discharge printing or reserve printing. A non-colored base material can be combined with the solution containing the bacterial strains and azo dyes and the like as described above.
