VALABio is now live 🚀
Our new project turns dairy & meat side streams into bioactive ingredients and diagnostics, from peptides to EVs.
Proud to coordinate this multidisciplinary effort.

🚀 New study on Propionibacterium freudenreichii:
🔹 B12 needed under low O₂, but not when oxygen is high
🔹 B2 always essential — external supply helps
🔹 Smart oxygen + vitamin control = better yields, lower costs

Study suggests that both regular-fat and low-fat dairy (milk, yogurt, cheese) show neutral associations with CVD risk. The focus should shift to reducing nutrient-poor, energy-dense foods instead. #Nutrition #CVD #Dairy #DietaryGuidelines sciencedirect.com/science/ar…

Tämä on niin huippua! 🥳
#DanceYourPhD kisan voitto Suomeen Sulo Roukan @AgriForHelsinki biisille ja esitykselle.
🌶️🌶️🌶️
Tutkimuksesta viestintää voi toteuttaa näinkin.
Tästä hyvä jatkaa euroviisuihin. 💪

Cheese microbiota-associated bacteria can be traced in the human gut microbiota and may expand its functional repertoire, with potentially significant implications for human health. 🧀 Learn more in @AppEnvMicro: asm.social/2jA
ALT Microbial analysis workflow and taxonomic profile of cheese after cultivation in GESM. Panel a depicts the workflow followed to investigate the taxonomic, transcriptomic, and metabolomic outcomes obtained after a batch cultivation of raw milk cheese in a simulated gut environment. Panel b shows the hierarchical clustering approach based on Bray-Curtis matrix calculated on taxonomical profiles of cheese samples after GESM cultivation. In the center, the heat map displays the Bray-Curtis distance value matrix, highlighting the substantial taxonomic variability among cheese samples after GESM cultivation. Bar plots flanking the heat map illustrate the dominant bacterial species of raw cheese samples (left) and those cultivated on GESM medium (right). Only bacterial species with a maximum relative abundance of at least 10% across metagenomic samples were included.
Ravinto ei ole vain energiaa, vitamiineja ja proteiineja. Esim. tomaatin ja maidon nanokokoiset kalvorakkulat kuljettavat informaatiota ja päätyvät verenkiertoon. Lisää mielenkiintoisesta tutkimusaiheesta ravitsemuksen ja lääketieteen näkökulmasta: hs.fi/tiede/art-200001099941…

New study found eating #Camembert cheese could improve memory & protect the brain during aging (at least in mice)..
Camembert uses #Penicillium camemberti in its fermentation, which produces fatty acid amides that are rarely found in other cheeses.

Vitamin B12 in beer? Once an urban legend—since yeast don’t synthesize it. But thanks to @iida_l and team, B12🍺is now a reality! They added a fermentation step with cobalamin-producing Propionibacterium. Discover more: sciencedirect.com/science/ar… #b12vitamin #fermentation #foodtech
Our latest research shows how fermenting faba bean flour fortify plant-based meat analogues with vitamin B12 while reducing antinutrients. This approach enhances nutritional value and texture in high-moisture extrudates. @AgriForHelsinki #VitaminB12 shorturl.at/pk2Ua

Bovaer on näköjään uusi koronarokote*. Hienoa että biokemia (ja naudat) kiinnostavat, mutta otetaas pari asiaa selväksi.
* Ei ole, vaan nautojen rehulisäaine, joka vähentää niiden metaanipäästöjä jarruttamalla erästä pötsimikrobien entsyymiä. Eikä tätäkään myy Bill Gates.
🚀Hold onto your lab coats! 🧪 We tossed our favorite B12 producer, Propionibacterium freudenreichii, into the oxygen pool and it thrived! Under oxygen, it bulks up on biomass, overproduces heme, and even cuts back on its famous B12! journals.asm.org/doi/10.1128…

Pari muistutusta juhannukseen;
🧀 Halloum grillataan kokonaisena
🧀 Provolone on paras burgeriin
🧀 Gorgonzola pihvin päälle
🧀 Jos juusto on yli 3 vkoa vanhaa, se on laktoositon
🧀 Koiralle juustoa myös ☝🏻
🧀 Ei väliä mitä juustoa on leivällä kunhan on
Juustoista juhannusta!
