the plot thickens 👇 as we all suspected and feared(?), organellogenesis is not straightforward, but rather, well,... a thicket ¯\_(ツ)_/¯

Here’s a teaser of how we did it 🧵👇1/5

Synthetic C1 metabolism in Pseudomonas putida enables strict formatotrophy and methylotrophy via the reductive glycine pathway | mBio

Soluble C1 feedstocks, such as formate and methanol, have gained attention as sustainable substrates for biotechnology, with the potential to reduce greenhouse gas emissions and reliance on sugar-based resources. Despite their promise, the metabolic ...

Metabolic interplay drives population cycles in a cross-feeding microbial community

Metabolic interplay drives population cycles in a cross-feeding microbial community - Nature Communications

Here the authors leverage a crossfeeding, engineered microbial community to demonstrate that strain abundance cycles are robust across environmental conditions. They pair this with a nonlinear dynamic model to elucidate population cycles.

The original plan was to isolate >50 phage-host combos (I naively thought this would be the straightforward bit of the project—it wasn’t). Eventually we got 2 phages tripling the number of genome-sequenced, in vitro characterised Strep. suis phages! Read about Bonnie & Clyde👇🏿
