What if bacteria were using wax esters to shape skin microbiomes? Staphylococcal lipases convert skin antimicrobial fatty acids into harmless wax esters. This publication is the very first first-author paper for my first PhD student, my first time acting as last author, and our first ISME paper.

After having to deal with fracture-related infection and its impact, up close and personal within my family during the past year, our latest research publication hits different... Deeply dedicated to see our 'Fibrilysins' developed towards clinical use in the near future.

Happy to see the work of @laucamus.bsky.social published today (rdcu.be/i9p3mJUiX3ta); We show that S. aureus proliferation in nasal communities is impacted by amino acid availability. With amazing support of @linklab.bsky.social, L. Angenent and many more. @lmu.de, @unituebingen.bsky.social
