Identification of Microorganisms (Fungi) in Fermented Ganjang from Korea, China, and Japan Using Next-Generation Sequencing Analysis

This study analyzed the identification and community structure of fermented Ganjang microorganisms (fungi) in Korea, China, and Japan using the next-generation sequencing (NGS) analysis method. The results of selecting the top 10 fungal species in three samples at the species level for the distribution of fungi in Korean and Japanese Ganjang showed that Millerozyma farinose species was the most abundant on average, followed by Zygosaccharomyces rouxii, Wickerhamiella versatilis and Sterigmatomyces species. In Korean Ganjang K1 sample, Millerozyma farinosa was detected the most at 90.85%, and in Japanese sample J2 sample, Zygosaccharomyces rouxii was detected the most at 52.46%, showing differences in dominant fungi.
