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.

Environmental ecology review presents how microbial life strategy concepts are applied in complex microbial communities.   Two interesting model systems are described in the techniques section, plus potentially scalable workflow for the preparation of high potency Akkermansia muciniphila cells for therapeutic interventions.  The importance of understanding the role of the microbiome in preventing complications after organ transplant and surgeries are discussed in two reviews.   Another study shows that proton pump inhibitors used to prevent gastric ulcers were associated with distinct gut microbiota signatures.  For faster wound healing, try some saliva. A study shows the beneficial effects of saliva on wound healing in human epidermal keratinocytes and on the attenuation of intracellular Staph. aureus infection.
