Abut 100 strains f lactic acid bacteria shwing blue clny n the MRS agar medium cntaining X-gal were islated frm several kinds f Kimchi. Amng them, 2 strains were selected as ptential β-galactsidase prducers. The selected strains, ET-1 and LA-12, were identified as Lactbacillus fermentum and L. acidphilus, respectively by the analysis f 16S rdna sequences. They shwed relatively high β-galactsidase activity and cellular viability. Their β-galactsidase shwed the highest activity at 55 C. And the ptimum phs f the enzymes prduced by ET-1 and LA-12 were ph 5.5 and ph 7.0, respec-

7 222 Yung-Ki Lee et al. Kr. J. Micrbil tively. They were als highly resistant t artificial gastric juice and bile. Tw selected strains shwed little change f viable cell number fr 3 hr incubatin in artificial gastric juice, and maintained the viable cell number at 10 8 CFU/ml fr 24 hr in 0.3% xgall after incubatin fr 2 hurs in artificial gastric juice. Based n these results, ET-1 and LA-12 are expected t be applied in dairy industry.
