Abstract
|
|
|
|
A lactic acid bacterium LP2 strain, which was previously isolated from a natural cheese, was confirmed to produce 1,4-dihydroxy-2-naphthoic acid (DHNA), a bifidogenic growth factor. The strain was identified as Lactobacillus plantarum (99% identity) by a homology search of the 16S rRNA gene sequence and named Lactobacillus plantarum LP2. The culture supernatant of the strain presented an antimicrobial activity against Helicobacter pylori KCTC 12083, where the DHNA might have influenced on the activity.
