Sorry for the delayed post, WordPress was playing some mean tricks on me today and there were no treats! Good morning all and happy spooky season! It’s been a moment since I’ve written a post and I write to you now as a freshly (pepper)minted PhD! I’m feeling gourd and can’t wait to pumpkin spice things up with some fangtastic papers.

Some of the highlights include a paper by McAlpine et al. examining interkingdom relationships between bacteria and fungi. Specifically, they found that the gut commensal species Lactobacillus can produce a small molecule that blocks filamentous growth of the opportunistic pathogen Candida albicans. Another interesting paper comes from Michael Adams lab at the University of Georgia, Athens which showed that members of the gut microbiota have the capacity to assimilate the metal tungsten which, in turn, allows these microbes to oxidize a broad range of aldehydes in the gut. Additionally, a paper by Plummer et al. looked at the vaginal microbiota of women who have recurrent bacterial vaginosis as well as the penile microbiota of their partners, and found that when males also underwent antibiotic treatment it led to a decrease in bacterial vaginosis in their female partners.

Hope you enjoy reading these fa-boo-lous papers and may you eat, drink, and be scary this Halloween!

Hyvää Päivää from Helsinki, Finland ! Today’s digest contains a selection of really interesting preprints and published studies. If you are interested in soil microbiology, take a look at the preprint by Nelson and collaborators, who characterized the soil microbiome across a wildfire burn severity gradients in coniferous forests and made their dataset available in the Fire Responding Ecogenomic database (FiRE-db).

Looking at a large variety of ecosystems, Rodriguez-Gijon and collaborators used a vast collection of Metagenomes Assembled Genomes (MAGs), to investigate the genomes size of prokaryotes in these ecosystems. They show that, while the environment of origin can be linked to genome size, it seems like evolutionary phylogenetic history is in many cases a stronger predictor.

Finally, today’s non-microbiology pick is a great “10 simples rules” paper reviewing best practices on organizing bioinformatics workshops in low and middle-income countries.

Have a great Weekend!
