Abstract

Antibacterial properties of Lactobacillus strains isolated from traditional fermented mustard were investigated. Among the strains tested, strain B0105 was found to produce bacteriocin-like compounds against Streptococcus mutans BCRC 10793. Strain B0105 was identified as Lactobacillus plantarum by phenotypical and physiological tests as well as16S rDNA identification. The molecular weight of bacteriocin-like compounds was 3.5 and 4.7 kDa by Tris-Tricine SDS-PAGE. In addition, this bacteriocin-like exhibited a strong antibacterial activity, heat stability (15 min at 121°C) and pH stability (pH 2.0–4.0) againstS. mutans BCRC 10793, however, it was sensitive to proteolytic enzyme. Overall, the results obtained, demonstrate that strain B0105 is able to produce bacteriocin-like compounds inhibiting S. mutans BCRC 10793, making it potential candidate for antibacterial agents.

 

Key words: Lactobacillus plantarum, bacteriocin, Streptococcus mutans.
