dc.description.abstractPhylogenetic relationship and strains sub-typing of Bacillus species isolated from iru, a traditional fermented condiment in Africa were studied using polyphasic genomic approaches and the profiles compared with bacilli isolated from similar Asian condiments. The 16S rRNA gene sequencing identified the strains as Bacillus subtilis, Bacillus amyloliquefaciens, Bacillus cereus, Bacillus licheniformis, Bacillus pumilus, and Brevibacillus formosus. The phylogenetic analysis conducted showed five distinct clusters with genetic relatedness among B. subtilis and B. amyloliquefaciens strains from Africa and Asia. Amplified ribosomal DNA restriction analysis (ARDRA) successfully differentiated species of B. subtilis phylogeny from B. cereus. Combined analyses of ARDRA, internal transcribed spacer-polymerase chain reaction (ITS-PCR), ITS-PCR-restriction fragment length polymorphism (ITS-PCR-RFLP) and randomly amplified polymorphic DNA (RAPD-PCR) further confirmed B. subtilis and B. amyloliquefaciens as the dominant Bacillus species associated with fermentation of iru, and revealed high strains genetic diversity, while multilocus sequence analysis (MLSA) data distinguished B. cereus from B. thuringiensis. This information is essential for selection of starter cultures with desirable functional attributes to guarantee product consistency and safety quality of traditional fermented foodsen_US
