Good morning! Today’s microbiome digest is brought to you by mild insomnia induced by a mid-afternoon coffee. It includes two food related studies, one on pathogenic E. coli found in ready-to-eat foods and the other focused on a antifungal lipopeptide produced by B. velezensis isolated from honey, and an an article focused on a new approach for processing frozen lung and lavage samples for use in microbiome studies. Also included are several articles focused on the gut microbiome, and several preprints focused on soil microbiome studies. Finally, I want to highlight a piece that details the positive outcomes associated with the National Summer Undergraduate Research Project (NSURP). Registration for this year’s program is still open until April 15th, and the organizers are looking for both mentors, mentees, and donors!
