- Abstract
- Strain NK34 was characterized for probiotic use. Strain NK34 was named Lactococcus lactis NK34 based on API 50 CHL kit results and 16S rDNA sequencing. L lactis NK34 was highly resistant to artificial gastric juice (pH 2.5) and artificial bile acid. Based on results from the API ZYM kit, 4 enzymes were produced. L. lactis NK34 was resistant to all antibiotics tested except for 10 mu g/mL roxithromycin and 10 mu g/mL erythromycin. The cholesterol-lowering effect of L lactis NK34 was about 46.9%. Concentrations of interleukin (IL)-1 alpha in the 20x concentrated supernatant of L. lactis NK34 was about 361 pg/mL. L lactis NK34 was also found to inhibit the growth of colon cancer cells due to MNNG-induced DNA damage. These results demonstrate the potential of L lactis NK34 as a health-promoting probiotic.
