"measured the growth effects of 308,461 #yeast variants, identifying 18,009 with significant effects"

James Boocock@theboocock.bsky.social

Excited to share our preprint! “Genome-scale base editing reveals the functional effects of variants in yeast” Using high-throughput base editing, we measured the growth effects of 308,461 variants, identifying 18,009 with significant effects. #Genomics #CRISPR 1/8 www.biorxiv.org/content/10.6...

New study out in #Yeast: Samer El Khoury, Cecile Grondin, Hugo Devillers, Marizeth Groenewald and @jllegras.bsky.social analyzed the genome of the Metschnikowia pulcherrima complex to resolve #taxonomic issues regarding the classification of this species. 👇 onlinelibrary.wiley.com/doi/10.1002/...

While book chapters are frequently a bear to write, it’s always thrilling to get a physical object at the end. Thanks to my coauthors Chris and Barbara! We got the intro to yeast chapters for this nice volume from MBAA.

Very interesting story on #Aspergillus westerdijkiae in cheese caves! #fungalevolution

Benjamin Wolfe@benwolfe.bsky.social

Over the past decade, a toxic fungus that destroys cheese rinds has been popping up in cheese caves throughout New England. In a new paper from my lab, we tried to better understand this emerging threat to New England's artisan cheese industry. doi.org/10.1128/aem....

"profiled fitness responses to over 600 bioactive and natural compounds, revealing broader and more polarized bioactivity than the standard #yeast gene-deletion collection" #Saccharomyces

Joseph Schacherer@schacherer.bsky.social

Excited to share our latest #haploteam paper! We developed a barcoded collection of 520 natural yeast isolates to screen 600+ compounds at population scale, uncovering how natural genetic variation shapes chemical responses. Congrats to Abhishek and Marion, who led this work! doi.org/10.1038/s414...

"fungi are reliable biomarkers for gut maturation, with the notable emergence of #Saccharomyces and Malassezia as some of the strongest indicators. Fungal composition was strongly associated with infant age and with the later development of both atopic dermatitis and food allergy" #mycobiome

Nature Portfolio@natureportfolio.nature.com

The results of a study in Nature Communications highlight the early life mycobiome as a potential therapeutic target to mitigate allergic disease development. go.nature.com/4xO6pST #microbiome #medsky 🧪

1/2 Happy to share this #Saccharomyces epidemiological study led by @renatokovacs1.bsky.social: retrospective analysis of all patients with S. cerevisiae isolated from sterile body sites between January 2019 and December 2025 in Debrecen. Rare sterile-site infections associated with high mortality!

Renátó Kovács@renatokovacs1.bsky.social

rdcu.be/fk5fx Not all probiotics are harmless: our new study shows that Saccharomyces cerevisiae can cause rare but severe sterile-site infections in critically ill patients — especially in ICU settings, after GI surgery, or with central venous catheters. 🍄💊 with @pflieglerlab.bsky.social

2/2 Among 196 patients with S. cerevisiae, 30 had sterile-site infections. 23% were paediatric cases. Bloodstream infections were the most common source (23%)! All in all, #Saccharomyces #yeast infections are not negligible but have been studied too sporadically! Few retrospective studies so far.

Most of my at-home fermentation experiments are successful, this one is not :) It took me a looooot of time to get my hands on viable and pure Monascus from red yeast rice products. After inoculating to steamed rice, the Rhizopus-like and Aspergillus-like molds took over the slow-growing Monascus:

Low-level contamination confounds population genomic analysis and also phylogenomics in this example of #yeast #Saccharomyces. Very important: "Contamination rates differed however among sequencing centers: was high for 2 #Saccharomyces studies (2% or 15% of genomes)."

Genetics Society of America@genetics-gsa.bsky.social

It is no surprise that contamination leads to incorrect conclusions in population genetics studies. @audreykward.bsky.social, @mcmomany.bsky.social, @dbensasson.bsky.social caution that even low-level contamination has a greater impact on analyses than expected. More in #G3journal: buff.ly/kYFXQfM

This week we conclude our General and Applied Microbiology Lab class with 1st year BSc students at UDebrecen. We spent the semester with studying sourdough yeasts and bacteria, with spp identification, genetic fingerprinting, and classic microbiological experiments. We also made new sourdoughs...

The new sourdoughs were identical but had various rare #yeast species from our sourdough collection added in triplicates. After continuous feeding, we will characterize the experimental sourdoughs for the microbiota and chemically as a follow-up project. Looking forward to see which one is best!

Fzata's new drug candidate, in fact a probiotic #Saccharomyces, FZ002, is designed to neutralize both of the main C. diff toxins (toxin A and toxin B).

Finally, after 8.5 years, this massive new farmhouse yeast paper is out! We've analyzed no less than 1760 yeast samples, and discovered that there is more farmhouse yeast than all known modern beer yeast put together. New results about contamination, too. www.garshol.priv.no/blog/440.html

Candida Genome Database’s new website is live! #yeast

Gavin Sherlock@gsherloc.bsky.social

The Candida Genome Database’s new website is now live! Everything has been entirely rewritten from scratch! A quarter of a century old Perl code (some of which I wrote!) producing HTML 2.0 (😬) is all gone, with modern python in its place, producing modern webpages with JavaScript and CSS to make
