TL;DR: Three robust clusters (referred to as enterotypes hereafter) are identified that are not nation or continent specific and confirmed in two published, larger cohorts, indicating that intestinal microbiota variation is generally stratified, not continuous.

TL;DR: The authors' classifications based on variation in the gut microbiome identify subsets of individuals in the general white adult population who may be at increased risk of progressing to adiposity-associated co-morbidities.

TL;DR: The 3,308,274-bp sequence of the chromosome of Lactobacillus plantarum strain WCFS1, a single colony isolate of strain NCIMB8826 that was originally isolated from human saliva, has been determined, and contains 3,052 predicted protein-encoding genes, suggesting that these genes form a lifestyle adaptation region in the chromosome.

TL;DR: Cell‐density‐dependent gene expression appears to be widely spread in bacteria, and genetic linkage of the common elements involved results in autoregulation of peptide‐pheromone production.

TL;DR: Efficient nisin-controlled expression (NICE) systems were developed for several different lactic acid bacteria and a promising application of the NICE system is the development of autolytic starter lactococci, which will lyse in an early stage during cheese ripening thereby facilitating the release of intracellular enzymes which can contribute to flavour formation.
