Reduction dye for indigo using bacterial strain

Abstract

The present invention relates to a reduction dyeing method for indigo using Dietzia sp. KDB1; being a reduction dyeing method which is relatively simple, efficient and allows good reproducibility, by using a Dietzia sp. KDB1 bacterial strain instead of a traditional fermentation process which entails poor reproducibility and is exacting and complicated. The method has the advantage of being able to substantially contribute to the field of dyeing using indigo, as the method can be used not only with natural indigo but also with synthetic indigo and makes it possible to efficiently increase the dye uptake of fabrics, and makes it possible to simplify difficult reducing processes including existing fermentation conditions which are exacting and complicated.
