Indigo is a fabric dye that requires reduction by microbial activity or chemical reagents to render it soluble in water. Sources of indigo for fermentation are primarily divided into composted indigo-containing plants and indigo extracted from plants. To elucidate the factors responsible for bacterial diversity, and for sustaining reduced state of indigo in different preparations, this study assessed fermentation-derived fluids using composted plant leaves, sukumo, and extracted indigo (Ryukyu-ai paste, and Indian indigo cake) prepared using different procedures.
