The Lactobacillus Bile Salt Hydrolase Repertoire Reveals Niche-Specific Adaptation
MSPHERE, 3(3).
Ed(s): C. Ellermeier
author keywords: Lactobacillus; bile acid; bile salt hydrolase; gastrointestinal tract; niche; penicillin V acylase; probiotic; therapeutic
MeSH headings : Adaptation, Biological; Amidohydrolases / genetics; Genetic Variation; Genotype; Lactobacillus / classification; Lactobacillus / enzymology; Lactobacillus / genetics; Penicillin Amidase / genetics; Phylogeny; Sequence Homology
TL;DR:
The BSH repertoire across 170 sequenced species revealed that BSH-encoding lactobacilli primarily adopt the vertebrate-adapted lifestyle but not the environmental or plant-associated subsets, and will guide future mechanistic studies of BSH activity and contribute to the development and selection of Lactobacillus strains with therapeutic potential.

Characterization and Exploitation of CRISPR Loci in Bifidobacterium longum
FRONTIERS IN MICROBIOLOGY, 8.
author keywords: CRISPR-Cas systems; genotyping; probiotics; Bifidobacterium longum
TL;DR:
It is suggested that CRISPR-Cas immune systems are instrumental in mounting diversified viral resistance in B. longum, and hypervariable loci can be used to gain insights into strain origin, evolution and phylogeny, and can provide discriminatory sequences to distinguish even clonal isolates.

2016 review
Deciphering and shaping bacterial diversity through CRISPR
[Review of ]. CURRENT OPINION IN MICROBIOLOGY, 31, 101–108.
MeSH headings : Bacteria / genetics; Bacteria / virology; Bacteriophages / genetics; CRISPR-Cas Systems / genetics; Clustered Regularly Interspaced Short Palindromic Repeats / genetics; Genome, Bacterial / genetics; Host-Pathogen Interactions / genetics
TL;DR:
Although the ability to target and cleave DNA in a sequence-specific manner is a powerful mechanism utilized by bacteria to fend off phage, plasmids, and potentially harmful nucleic acids, it is also a promising technology for programmable targeting of undesirable bacteria in microbiome consortia.
