Novel Siphoviridae phage PMBT4 belonging to the group b Lactobacillus delbrueckii subsp. bulgaricus phages.

A novel Lactobacillus delbrueckii bacteriophage PMBT4 was isolated from the Nigerian fermented milk product nono. The phage possesses a long and thin, non-contractile tail and an isometric head, indicating that it belongs to the Siphoviridae family. A neck passage structure (`collar`), previously hypothesized to be encoded by two genes located in the Lactobacillus delbrueckii phage LL-K insertion sequence (KIS) element, as well as in two additional Lb.

Isolation and Characterization of Potential Starter Cultures from the Nigerian Fermented Milk Product .

, an important traditional fermented dairy food produced from cow's milk in Nigeria, was studied for microbial diversity and for starter culture development for industrial production. On the basis of a polyphasic approach, including phenotypic and genotypic methods such as 16S rRNA gene sequencing, repetitive element PCR (rep-PCR) fingerprinting metagenomics, and whole genome sequencing, we identified () , , , and () as predominant bacterial species involved with milk fermentation during traditional production in Nigeria, while the predominant yeast species in was identified as . Using metagenomics, and potential pathogens such as enterobacteria were detected at low levels of abundance.

Draft Genome Sequences of Lactobacillus helveticus, Lactobacillus fermentum, and Lactobacillus delbrueckii Strains from African Fermented Nono.

The genomes of predominant , , and strains from fermented nono were sequenced. The genome sizes were 2.1, 1.
