Abstract
Halotolerant killer yeasts which showed killer activity in the presence of NaCl were isolated from fermented foods, such as miso, soy sauce and salted vegetables, and identified as Debaryomyces hansenii, Hansenula anomala, Candida naeodendra and Pichia farinosa. The killer strains of C. naeodendra and P. farinosa were found here for the first time. Seventy-six percent of the salted vegetable samples contained killer yeasts, mainly D. hansenii. On the other hand, killer strains were isolated from 3 of 18 samples of miso and soy sauce. The killer spectra against the standard killer strains, K1-K10, were different from those of other killer strains reported previously.
