TL;DR: Time courses obtained by targeted qPCR revealed that ‘blooms’ in specific bacterial groups occurred rapidly after a dietary change, and these were rapidly reversed by the subsequent diet.

TL;DR: It is argued strongly that R. bromii has a pivotal role in fermentation of RS3 in the human large intestine, and that variation in the occurrence of this species and its close relatives may be a primary cause of variable energy recovery from this important component of the diet.

TL;DR: This organization of starch-degrading enzymes is unprecedented and provides the first example of cohesin-dockerin interactions being involved in an amylolytic system, which is referred to as an “amylosome.”

TL;DR: Evidence is presented that Ruminococcus bromii has a superior ability to degrade certain forms of particulate resistant starch when compared with other highly abundant species of amylolytic bacteria found in the human colon and that this bacterium provides an example of a keystone species within the microbial community with respect to RS fermentation.

TL;DR: The metabolic benefits, for overweight adults, from WL were maintained through a subsequent WM diet with higher total carbohydrate intake and inclusion of resistant starch in the WM diet altered gut microbiota composition positively and resulted in lower fasting glucose compared with the control, with no apparent change in appetite.
