Abstract

Clostridium isatidis, an endospore-forming, indigo-reducing bacterium recently isolated from a woad dye vat prepared according to traditional methods, was also isolated from enrichments prepared from a variety of other indigo-yielding plant materials, and from material interpreted as dyebath waste from 10th-century Anglo-Scandinavian (Viking) deposits (York, U.K.). Genotypic identity of the new isolates with the original isolate was demonstrated by 16S rRNA gene sequencing. It is concluded that C. isatidis was the organism responsible for indigo reduction in the woad vats of the past. Copyright 2000 Academic Press
