Nice start of the week. MRA by Isabel Rigutto et al accepted for publication. We isolated several #nitrous oxide reducing bacteria including a Roseovarius strain that can link denitrification to C1 metabolism. Research supported by @erc.europa.eu Synergy project #MARIX 854088 accession PRJNA1300775

The new academic year didn't start with a MacBook, latte & cowork space or lectures, but with some real hands-on renovation and painting of my new hopefully future-proof, low maintenance digs, albeit literally in the back yard of Radboud University HQ. Luckily the RU sports centre is even closer 🏋️♀️
