Microbiota involved in fermented traditional Japanese indigo
In Japan, indigo-dyeing has traditionally been performed by natural fermentation. The indigo remains in a reduced state for 6 months, on average, although the fermentation fluid has a greater chance of being contaminated in an open environment, especially during the dyeing process. This fermentation system has several advantages for investigations on certain aspects of microbial ecology such as the functions of individual microorganisms and interactions between individual microorganisms. To understand the mechanisms underlying the changes in the initial fermentation phase that are concomitant with the initiation of indigo reduction, we made an indigo fermentation vat and took 7 samples from original indigo to fermented for 5.5 months. The bacterial V3-V4 region of 16S rRNA genes were PCR amplified for next-generation sequencing. Here are the data of these 7 samples.
