Did you ever wonder about vitamin B12 role in microbiome organization and function? using a chemical probe mimic of vitamin B12, the authors reveal a light- and B12-dependent DNA regulator and predict that organismal interdependencies for B12 may be critical to microbiome stability and overall function.  On the extremophiles front, a study provides an analysis of the genomic content of the most abundant bacterial inhabitants of the salt-secreting desert tree Tamarix aphylla.  An interesting paper reinforced linkages between the colonization of the foodborne pathogen E. coli O157:H7 in cattle and the nature of the microbial community inhabiting the digestive tract of super-shedders. And as for future generations, if you want to get your kids or students excited about microbiology, try an interactive tool created by Stanford bioengineers: the 3D printed microscope powered by your smartphone.

The new Microbiome Digest team

Microbiome Digest proudly presents: the New Microbiome Digest Team! From now on, Microbiome Digest will be taken over by a team of 21 enthusiastic scientist from all over the world.

I have tried to make this change as smoothly as possible, but I still anticipate some unanticipated SNAFU’s in the beginning. As we all need to adapt to this new style of publishing, there will probably be some irregularity in posting, some duplicate entries, or formatting issues. Or maybe you won’t notice anything at all!

Let’s give a warm welcome to the new Microbiome Digest team. Here is a short introduction to the new members (I am very short on time) – I will make a decent page with a better description in the near future.

Welcome on board!
