Good morning!

There are two particularly exciting papers today; a metagenomic analysis of the genera Akkermansia, providing evidence this is a primarily human microbiota member, and a paper aiming to further understand our knowledge of antibiotic exposure – finding significant alterations in neuronal gene expression in mouse pups.

Human gut microbiome

Development of a prebiotic blend to influence in vitro fermentation effects, with a focus on propionate, in the gut. Collins et al. FEMS Microbiology Ecology.

Genomic diversity and ecology of human-associated Akkermansia species in the gut microbiome revealed by extensive metagenomic assembly. Karcher et al. Genome Biology.

Pregnancy and Early life

Effects of early-life penicillin exposure on the gut microbiome and frontal cortex and amygdala gene expression. Volkova et al. iScience.

Animal experiments

Altered milk yield and rumen microbial abundance in response to concentrate supplementation during the cold season in Tibetan sheep. Lin-Sheng Gui et al. Electronic journal of Biotechnology.

Plant, root and soil microbiome

Time outweighs the effect of host developmental stage on microbial community composition. Dibner et al. FEMS Microbiology Ecology.

Food microbiology

Dynamics of dark fermentation microbial communities in the light of lactate and butyrate production. Detman et al. Microbiome.

Bioinformatics

A metabolomics pipeline for the mechanistic interrogation of the gut microbiome. Han et al. Nature.
