Chinese- and Japanese-type fermented soy sauces are made of different plant
materials. The lactic acid bacterium Tetragenococcus halophila is present
and grows in both types. On the basis of the difference in sugar
composition and content in the plant materials, differences in the
populations of T. halophila bacteria were expected. However, obvious
differences were found only regarding the utilization of l-arabinose. In
the Chinese type, almost all isolates utilized l-arabinose, while in the
Japanese type only 40% of the isolates did. Also, the population in the
Japanese type was more heterogeneous regarding substrate utilization.
Random amplified polymorphic DNA analysis revealed that the heterogeneous
population at the Japanese-type industrial manufacturer was derived from
only three strains at maximum. Genetic relatedness among isolates from
different soy sauce manufacturers was low, but protein fingerprinting
indicated that the isolates still belonged to one species.
