Taxonomy of Eurotium species isolated from meju.

Eurotium strains were isolated from 77 loaves of meju (dried fermented soybeans), in various regions of Korea from 2008 to 2010. Morphological characteristics and DNA sequences of ß-tubulin were examined. They were identified as Eurotium amstelodami, E. chevalieri, E. herbariorum, E. repens, E. rubrum, and E. tonophilum. Of these species, E. chevalieri and E. tonophilum had not been previously reported in association with meju. E. chevalieri and E. repens were the species isolated most frequently. This paper summarizes the morphological characteristics of six Eurotium species and provides key to identify the species from meju.
