Engineered yeast now produces succinic acid from plant sugars with an 85% yield, significantly lowering production costs and advancing sustainable alternatives to petrochemical-based methods. doi.org/g9wn2w
Ready for market: Engineered yeast boosts clean, cost-efficient chemical production
Building on their success developing a cleaner way to make valuable organic acids, researchers from the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) have pushed one product closer to commercialization with a major upgrade in yield.

Researchers have invented a system that captures carbon dioxide from ocean water and converts it to succinic acid, a key monomer used to make the commonly used biodegradable plastic polybutylene succinate. cen.acs.org/environment/... #chemsky 🧪

The unique #CellEnvelope of #corynebacteria: @tbharat-lab.bsky.social &co map the C. glutamicum cell surface, revealing a patchy S-layer & specific assembly of the PS2 protein, thereby informing our understanding of cell envelopes that contain #MycolicAcids @plosbiology.org 🧪 plos.io/3Y6JNgw
Left: The atomic model of the PS2 lattice is shown in top and side views. PS2 hexamers are repeated in the 2D sheet with a lattice constant of 176 Å. Each PS2 monomer is colored and labeled separately within the hexamer, which repeats throughout the lattice (with pore dimensions highlighted). The side view of the lattice shows the smooth surface facing the extracellular space and rough surface with coiled-coil segments protruding towards the MM. Top right: Interactions at the hexameric and trimeric interfaces are stabilized by both hydrophilic and hydrophobic residues. Bottom right: A cell envelope tomogram was used to overlay the cryo-EM structure of the S-layer onto the in situ S-layer tomographic density. A single slice of the tomogram is shown, with the overlayed PS2 S-layer lattice in green and the tomogram in grayscale. The S-layer (surface layer), MM (mycomembrane), IM (inner membrane), and Cytosol are labeled.

I was waiting two years to see this out!! The genomic location of bacterial genes is not random!!! Congratulation on the authors (Martin Lercher and Team!). www.science.org/doi/10.1126/...
Most bacterial gene families are biased toward specific chromosomal positions
The arrangement of genes along bacterial chromosomes influences their expression through growth rate–dependent gene copy number changes during DNA replication. Although translation- and transcription-...
