Patent number: 5908775Abstract: 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.Type: GrantFiled: September 14, 1995Date of Patent: June 1, 1999Assignees: Okasa Prefecture, Yushiro Chemical Industry Co., Ltd.Inventors: Wataru Sugiura, Keiko Nagai, Tadashi Yokoyama
