ABSTRACT
IMPORTANCE: Tetragenococcus halophilus is a halophilic lactic acid bacterium generally used as a starter culture in fermenting soy and fish sauces. Aggregating strains can be useful in fermenting and obtaining clear soy sauce because cell clumps are trapped by the filter cake when the soy sauce mash is pressed. However, the genetic mechanisms of aggregation in T. halophilus are unknown. In this study, we identified genes encoding aggregation factor and its regulator. These findings may provide a foundation for developing improved T. halophilus starter cultures for soy sauce fermentation, leading to more efficient and consistent clear soy sauce production.
