Francisco Cubillos

Big congratulations to Dilanaz Arisan (@rquatrini.bsky.social 's lab) and Pablo Quintrel (@fcocubillosr.bsky.social 's lab) for winning the best posters awards sponsored by the #Yeast journal at the @smbe-chile2025.bsky.social conference in Puerto Varas 🎉🎉🎉

We had an amazing @official-smbe.bsky.social satellite meeting in Puerto Varas. Great science, colleagues & Patagonian experience. Thanks the organizers @pablo-villa.bsky.social et al & SMBE for putting this together!

No te quedes fuera del @EMBO PhD course a realizarse en Chile entre el 13-24 de Octubre 2025 en Santiago. Becas para estudiantes de regiones disponibles.

📣 Attention!🚨🚨🚨🚨🚨🚨
We’ve extended the scholarship application deadline to June 27th.
Don’t miss your chance, submit your application and abstract

Would you like to make it to both?? Think about it!!!

🌳🌳 big sampling days in Australia hunting yeast in Nothofagus forests together w/ @cristianvarela and @katehowell Great southern hemisphere collaboration to make sense of yeast ecologyon this side of the world!

And now, we also have a 2-year postdoc position in the Stelkens Lab! 🧪 If you are interested in parallel evolution, genomics, yeast, and climate adaptation, this could be for you! Please apply through U Stockholm's job platform here: su.varbi.com/en/what:job/...

Hahahah not sure about that, but certainly curious about what we find!! Maybe Saccharomyces fischerensis!

Great experience this week at #SarahKnight’s lab in NZ sampling the local beech forest (Nothofagus relative’s), & giving a Departamental seminar to share our findings and common grounds between Chile & NZ. So much in common!! Yeast 💪🏽💪🏽🌳🌳 @ibiochile.bsky.social

Schematic of lab and field experiments testing for yeast fitness with and without killer viruses. Panel A depicts a classical fitness assay in which a yeast with a virus (or cured of the virus) is cultured with a viral toxin-resistant reference strain and the number of doublings is compared between the two yeasts. Panel B diagrams field chambers made of 12-ml tubes in which a membrane holding yeast cells lines the mouth of the tube; the tube is then buried next to a tree. Panel C depicts a field experiment with the chambers. Yeasts hosting (or cured of) viruses are mixed with virus toxin-resistant reference cells, put onto chamber membranes, and incubated in soil for fifteen days. The relative ratios of tested and reference strains are then used as a proxy for fitness.

Check out my latest paper on fitness costs and benefits of hosting a killer virus if you're a yeast in the forest!

Spoiler alert:
In a few days we will announce around 30 PhD positions for the Cluster of Excellence Circular Bioengineering, one of them in my lab at @bokuvienna.bsky.social on synthetic single carbon pathways in yeast. Stay tuned!

This week we’ve been in Bariloche (ARG) sharing the main results on our novel lager yeasts & whisky prototype. Happy to be here thanks to @embo.org 😃🌳 for the @embo.org global investigator lecture at the IWOBY conference. @ibiochile.bsky.social

Registration is open for @official-smbe.bsky.social
satellite meeting in Chile. We have a great lineup of speakers for topics in Microbial ExpEvo and Adaptation 👏👏
Please consider attending. Plenty of scholarships for students and postdocs!

Hola! 😅 Can I just add something? ‘The Holarctic S. eubayanus are poor beer makers’ since they lack the MAL genes. Patagonian S.e. have multiple MAL copies and make ‘average’ beers 😂. Glad to see S. eubayanus talks!

Laboratory yeast strains are highly diverse in lipid metabolism

Happy to share this JOVE MS, we provide details on live-tracking maltose metabolism activation in yeast using LUC. We used our ❤️Patagonian Sacch. eubayanus to show how activitation proceeds under beer fermentation 🧐 🍺
