Weissella koreensis is a psychrophilic bacterium that is the dominant species found in kimchi and exhibits anti-obesity effects via its production of ornithine. In this study, we mined the genome of W. koreensis KACC15510 to identify species-specific genes that can serve as new targets for the detection and quantification of W. koreensis in kimchi. A specific polymerase chain reaction (PCR) pri...

A gram-positive, nonmotile, irregular, short, rod-shaped new strain of Weissella confusa bacterium was isolated from fermented cabbage. The isolate was physiologically and biochemically characterised. The 16S rDNA was amplified by polymerase chain reaction (PCR). The isolate was identified as Weissella confusa (GenBank accession number: GU138518.1) based on nucleotide homology and phylogenetic ...

Fermented herbal juices are widely consumed all over the world especially in Thailand. Thai people believe that these herbal juices can prevent and cure disease, and are supplemented as a health promoting beverage said to have anti-aging properties. Lactic acid bacteria (LAB) fermented beverages (LAFB) such as EM-X, fermented soybean broth, and Kefir have been widely used by world population. E...

The bacterial communities of Zaopocu (ZPC), a tropical specialty fermented food in Hainan Island, were characterized this study using high-throughput sequencing. Firmicutes and Proteobacteria the two dominant phyla. primary genus ZPC_A was Weissella, while ZPC_B ZPC_C had Lactobacillus as genus. biomarker lactic acid bacteria (LAB) brevis, Weissella confusa, Leuconostoc citreum, whereas amyloly...

The Ghanaian cocoa bean heap fermentation process was studied through a multiphasic approach, encompassing both microbiological and metabolite target analyses. A culture-dependent (plating and incubation, followed by repetitive-sequence-based PCR analyses of picked-up colonies) and culture-independent (denaturing gradient gel electrophoresis [DGGE] of 16S rRNA gene amplicons, PCR-DGGE) approach...

Viable and nonviable Weissella confusa strain PL9001 inhibited the binding of Helicobacter pylori to human gastric-cell line MKN-45 cells by more than 90%. Spent culture supernatant of PL9001 rapidly decreased the viability of H. pylori, rupturing cell walls. The results suggest that PL9001 is a probiotic that can reduce the infectivity and persistence of H. pylori.
