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. The reducing activity of indigo correlated with the particle size after the addition of lignin.
