Even good things come to an end. After many weekends of bioreactor service, it’s time to pass the torch Our favorite pet bugs, #Anammox, #Methanoperedens, #Comammox & many others, will now be in the good hands of the next generation. The future of #microbiology @ribesresearch.bsky.social is bright!

Looking to recruit 3 grad researchers. (1) Drinking water micro-ecology, (2) Nitrogen micro (specifically comammox), and (3) Algal micro + imaging. as Spring 2024 & late as Fall 2024. if you know someone creative + motivated + interested in these topics - would appreciate u sharing this with them.

Excited to see this work from @ribesresearch.bsky.social about obtaining comammox and AOB using Cu-MMO labeling and FACS is finally out!

Hoping novel enrichment techniques will enable us to characterize more comammox isolates. Fingers crossed for the isolation/enrichment of a clade B comammox 🤞
