Abstract
For the control of dental plaque by the use of lactic acid bacteria(LAB), LAB from Kimchi samples was isolated on Rogosa SL or MRS agar plates and tested for the inhibitory effect on the formation of artificial plaque by Beaker-wire test. One strain inhibiting artificial plaque was selected and identified. The effects on the formation of artificial plaque and the multiplication of Streptococcus mutans were also studied.
1. Among 456 isolates from 154 Kimchi samples, KM214 strain was isolated.
2. KM214 strain inhibited the formation of artificial plaque by Streptococcus mutans upto 71% when compared to the control(p(0.001).
3. KM214 strain inhibited the synthesis of insoluble glucan by S.´ mutans upto 79% when compared to the control(p (0.001).
4. KM214 strain had little effect on the multiplication of S. mutans.
5. The formation of artificial plaque by S. mutans was inhibited upto 50% by the addition of culture supernatant of KM214 when compared to the control(p (0. 001).
6. The isolated strain was identified as Lactobacillus plantarum and named as Lac. plantarum KM214 on the basis of cultural, physiological, biochemical characteristics and carbohydrates fermentation patterns.
