However, in this study, the mixed culture with Z.rouxii and a late maturing yeast P.guilliermondii did not seem to be suitable for the preparation of salt-reduced soy sauce. Instead, a mixed indigenous culture with T. delbrueckii JBCC-623 replacing Z.rouxii could achieve a balance of volatile flavors having an identical flavor profile pattern to high-salt soy sauce due to better adaptability of the indigenous strains for developing flora. Nevertheless,Z. rouxii and T. delbrueckii, whose genera branched from the Saccharomyces genus, are expected to play similar roles in soy sauce fermentation (Fig. 1).
