| Popis: | Aspergillus sojae is a koji (starter) mold that has been applied for food fermentation in Asia. The whole genome of A. sojae SMF 134, which was isolated from meju (Korean soybean fermented brick), was analyzed at the genomic level to evaluate its potential as a starter for soybean fermentation. The genome size was 40.1 Mbp, which was expected to be composed of eight chromosomes with 13,748 ORFs. Strain SMF 134 had a total of 151 protease genes, among which two more leucine aminopeptidase (lap) genes were found in addition to the previously known lap 1, and three γ-glutamyltranspeptidase (ggt) genes were newly identified. Such genomic characteristics of SMF 134 with many protease and flavor-related (lap and ggt) genes support its merits as a starter for soybean fermentation. In addition, this first complete genome of A. sojae will allow for further genetic studies to better understand the production of various enzymes, including proteases, LAPs, and GGTs, as well as other characteristics as a starter mold for soybean fermentation. |
