πŸ“’ New preprint on bioRxiv!

We introduce V4-EXT, a revised 16S rRNA V4 primer set that dramatically improves detection of Patescibacteria and other undersampled lineages

βœ… 938 samples
βœ… More novel ASVs

Primer choice matters πŸ‘€

Sulfoquinovose is exclusively metabolized by the gut microbiota and degraded differently in mice and humans - Microbiome Background Sulfoquinovose (SQ) is a green-diet-derived sulfonated glucose and a selective substrate for a limited number of human gut bacteria. Complete anaerobic SQ degradation via interspecies metab...

Our recent paper by @julkras.bsky.social provides further insights into the metabolism of sulfoquinovose in humans and lab mice, and its prebiotic potential.

During homeostasis, host-driven habitat filters, such as the maintenance of anoxia by epithelia Ξ²-oxidation and stable iron levels through dietary intake, curate a diverse microbiota dominated by beneficial obligate anaerobic primary fermenters. Upon onset of diverse inflammatory intestinal disease states, including inflammatory bowel disease and colorectal cancer, host habitat filters become compromised. Inflammation-driven increases in luminal oxygen levels favor facultatively anaerobic pathobionts at the expense of commensal obligate anaerobes. In parallel, host nutritional immunity factors, such as lactoferrin, sequester iron to defend against potential bacterial pathogens. These environmental perturbations can drive the microbiota to an imbalanced, pro-inflammatory dysbiosis. However, a resilient microbiota can withstand or rapidly recover from these perturbations until host habitat filters are restored. The mechanisms that mediate this resilience and restoration of host habitat

Understanding microbiota resilience in the face of imbalances is crucial for maintaining host health. This #mBio review explores microbiota resilience, emphasizing the interplay between microbial communities and host-driven environmental controls. asm.social/2qW

New preprint @julkras.bsky.social et al.

We show that degradation of sulfoquinovose, ubiquitous in plants and algae, is a core function of the cow rumen microbiome

and describe novel SQ-metabolizing taxa.
