Characterization of novel bacteriocin PB2 and comprehensive detection of the pediocin gene ped-A1 from Pediococcus pentosaceus PB2 strain isolated from a sorghum-based fermented beverage in Nigeria.

Lactic acid bacteria (LAB) have been known to possess bacteriocidal activity resulting from ribosomally synthesized antimicrobial peptides called bacteriocin. This study focused on the characterization of the bactericidal activity of bacteriocin PB2 and comprehensive detection of the pediocin ped-A1 from obtained from fermented sorghum beverage, , in Nigeria against ATCC 25922 and ATCC 15313. Bacteriocin PB2 was purified in a 2-step purification using 80% NH (SO), and Carboxymethyl-Sephadex G-50 column chromatography to achieve a 12.

Genomic, biochemical and microbial evaluation of probiotic potentials of bacterial isolates from fermented sorghum products.

Fermented products, including and , provide several health benefits, particularly when probiotics are used in the fermentation process. Probiotic microorganisms exert strain-specific health-promoting activities on humans and animals. The objective of this study was to investigate the probiotic potentials of Lactic-acid bacteria (LAB) isolates from indigenous fermented sorghum products ( and ).

Unique Clones of Vibrio cholerae O1 El Tor with Haitian Type ctxB Allele Implicated in the Recent Cholera Epidemics from Nigeria, Africa.

Background And Objectives: The antimicrobial susceptibility patterns and genetic characteristics of Vibrio cholerae O1, which is responsible for several cholera epidemics in Nigeria, are not reported in detail since 2007. In this study, we screened V. cholerae O1 El Tor biotype isolates from cholera cases and water samples from different states to investigate their phenotypic and genetic attributes with special reference to their clonality.
