Researchers identify bacterial mechanism for vitamin B12 uptake

A team of scientists led by Dr. Ulrich Kleinekathöfer, professor of Theoretical Physics at Constructor University in Bremen, has now discovered how B12 is absorbed by certain intestinal bacteria. Published in the journal ...

Boosting survival of a beneficial bacterium in the human gut

The microbes that inhabit the gut are critical for human health, and understanding the factors that encourage the growth of beneficial bacterial species—known as "good" bacteria—in the gut may enable medical interventions ...

Study identifies gut bacteria that regulate cholesterol

Certain species of bacteria in the gut interact with and help balance levels of dietary cholesterol by using it to create a molecule that plays important roles in human health, according to a study published August 18 in ...

Common food additive causes adverse health effects in mice

A common food additive, recently banned in France but allowed in the U.S. and many other countries, was found to significantly alter gut microbiota in mice, causing inflammation in the colon and changes in protein expression ...

How humans and their gut microbes may respond to plant hormones

A bowl of salad contains more than vitamins and minerals. Plant matter also includes remnants of the hormones plants produce to control how they grow, age, and manage water intake. Recently, scientists have reported that ...

Unparalleled inventory of the human gut ecosystem

An international team of scientists has collated all known bacterial genomes from the human gut microbiome into a single large database, allowing researchers to explore the links between bacterial genes and proteins, and ...
