Unique adaptations in sulfatases underpin colonic mucin degradation by Akkermansia muciniphila
Abstract Excessive foraging of colonic mucin glycans by gut bacteria is associated with diseases such as inflammatory bowel disease. Although Akkermansia muciniphila is an important mucin degrader, the role of carbohydrate sulfatases that facilitate digestion of these heavily sulfated glycans remains unclear. Combining in vitro digestion assays, proteomics and structural biology, we show that A.

Ruminococcus torques is a keystone degrader of intestinal mucin glycoprotein, releasing oligosaccharides used by Bacteroides thetaiotaomicron
Abstract Symbiotic interactions between humans and our communities of resident gut microbes (microbiota) play many roles in health and disease. Some gut bacteria utilize mucus as a nutrient source and can under certain conditions damage the protective barrier it forms, increasing disease susceptibility.
Fiber deprivation and microbiome-borne curli shift gut bacterial populations and accelerate disease in a mouse model of Parkinson’s disease
Highlights • Fiber deprivation shifts microbiome structure and affects gut barrier • Curli accelerates alpha-synuclein pathology in colon and brain • Combining challenges replicates and accelerates Parkinsonian features Summary Parkinson’s disease (PD) is a neurological disorder characterized by motor dysfunction, dopaminergic neuron loss, and alpha-synuclein (αSyn) inclusions. Many PD risk factors are known, but those affecting disease progression are not.
If You Eat It or Secrete It, They Will Grow: the Expanding List of Nutrients Utilized by Human Gut Bacteria
Minireview Robert W. P. Glowacki, Eric C. Martens William Margolin, Editor DOI: 10.1128/JB.00481-20 ABSTRACT In order to persist, successful bacterial inhabitants of the human gut need to adapt to changing nutrient conditions, which are influenced by host diet and a variety of other factors.

Reports from a Healthy Community: the 7th Conference on Beneficial Microbes
Meeting Review Mark J. Mandel, Nichole A. Broderick, Eric C. Martens, Karen Guillemin Harold L. Drake, Editor DOI: 10.1128/AEM.02562-18 ABSTRACT The last two decades have seen an explosion in research about the beneficial microbial communities associated with plants and animals. Initially, this explosion was driven by technological advances that enabled explorations of microbiomes on unprecedented scales.

Lactobacillus acidophilus Metabolizes Dietary Plant Glucosides and Externalizes Their Bioactive Phytochemicals
Therapeutically active glycosylated phytochemicals are ubiquitous in the human diet. The human gut microbiota (HGM) modulates the bioactivities of these compounds, which consequently affect host physiology and microbiota composition. Despite a significant impact on human health, the key players and the underpinning mechanisms of this interplay remain uncharacterized.

Could gut bacteria that help us digest beer & bread fight disease, too?
ANN ARBOR, Mich. -- Bacteria that have evolved to help us digest the yeast that give beer and bread their bubbles could support the development of new treatments to help people fight off yeast infections and autoimmune diseases such as Crohn’s disease, researchers report. The study shows how microbes in our digestive tract have learned to unravel the difficult to break down complex carbohydrates that make up the yeast cell wall.
