Effects of lignin on indigo-reducing activity and indigo particle size in indigo dye suspensions

Bioscience, Biotechnology and Biochemistry
Abstract Microbial indigo reduction is a key reaction in indigo dyeing; however, the mechanism of the interaction with indigo remains unclear. We hypothesized that lignin is a candidate substance that supports this interaction. The addition of lignin effectively enhanced the indigo reduction.
