摘要:
A dye which is durable for practical use in the field of coloring automobile seat materials for which a good light-fastness is required and a dyeing method making use of the dye is provided. In the method, a disazo dye is obtained by converting guanazole to a tetrazo compound and coupling the tetrazo with an indole derivative to form a compound which is then quaternized using e.g., an alkylating agent resulting in a red dye with superior light-fastness at high temperatures.

Bacillus sp. NTAP-1 having been deposited under accession number FERM BP-6926; and a collagen-decomposing enzyme produced by bacterium. The above enzyme (1) has a capability of hydrolyzing, at the highest efficiency, collagen and gelatin from among casein, gelatin, albumin and collagen; (2) shows the optimum pH of 3.5 to 4.5; (3) shows the optimum temperature of 65 to 70° C.; (4) after heating at 60° C. at pH 6.0 for 4 hours, sustains an activity amounting to 60% or more of the level before the heat treatment; (5) remains stable at pH 3 to 6; and a molecular weight of approximately 46,000 when measured by SDS-PAGE.
