ABSTRACT
Post-fermented tea production involving microbial fermentation is limited to a few regions, such as Southeast Asia and Japan, with Japan's Shikoku island being particularly prominent. Lactiplantibacillus plantarum was the dominant species found in tea leaves after anaerobic fermentation of Awa-bancha in Miyoshi City, Tokushima, and Ishizuchi-kurocha in Ehime. Although the draft genome of L. plantarum from Japanese post-fermented tea has been previously reported, its genetic diversity requires further exploration. In this study, whole-genome sequencing was conducted on four L. plantarum strains isolated from Japanese post-fermented tea using nanopore sequencing. These isolates were then compared with other sources to examine their genetic diversity revealing that L. plantarum isolated from Japanese post-fermented tea contained several highly variable gene regions associated with sugar metabolism and transportation. However, no source-specific genes or clusters were identified within accessory or core gene regions. This study indicates that L. plantarum possesses high genetic diversity and that the unique environment of Japanese post-fermented tea does not appear to exert selective pressure on L. plantarum growth.
