New APC paper in Molecular Nutrition & Food Research.
First author Felipe Miceli de Farias & colleagues identifed a new circular bacteriocin from Streptococcus. The study is part of the research of Prof. Paul Ross's group at APC.

We previously engineered Saccharomyces cerevisiae through CRISPR-Cas9 integration to produce Ply511, a bacteriophage endolysin active against L. monocytogenes, showing the potential of engineered yeast to produce endolysins for biocontrol. In this study, we extended this approach to the probiotic yeast S. boulardii and directly compared the two yeasts as secretion hosts for Ply511. Using a simulated human gastrointestinal environment, we evaluated their ability to retain endolysin activity and reduce L. monocytogenes levels.

Estropausal gut microbiota transplant improves measures of ovarian function in adult mice - Nature Aging To investigate the link between the gut microbiome and ovarian health, here the authors transplant gut microbiota from estropausal female mice to young adult female mice. Microbial transplantation imp...

Very cool paper www.nature.com/articles/s43...

The authors found that FMTs from *older* mice into adult females improved ovarian function and lowered inflammation.

FMTs from younger mice into adult mice led to higher inflammation and *reduced* ovarian function in older mice.

SFA Talks from @Kristinacampbell, Sean Gibbons, and Howard Bauchner offered invaluable wisdom on science communication, career development, and strategies for publishing in high-impact journals! 🙌 #ISAPP2025

This year marked my first @isappscience.bsky.social annual meeting as part of the @isappsfa.bsky.social executive committee (Communications)
Brilliant science, thoughtful discussion, and great company throughout.
A huge thank you to my fellow committee members, I’m already excited for next year!
