New preprint this time through a fantastic collaboration with @jorgebarriuso.bsky.social and team. We have discovered the genetic basis behind the remarkable ability of Pseudomonas putida JM37 to use the PET #plastic monomer ethylene glycol as a growth substrate! www.biorxiv.org/content/10.1...

Pseudomonas putida JM37 as a novel bacterial chassis for ethylene glycol upcycling

Ethylene glycol (EG), one of the main monomers of polyethylene terephthalate (PET), is an attractive target for microbial upcycling. Despite this interest, there is a limited number of described organ...

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.

Preprint alert!! Delighted to share Eve Nery's work exploring the evolutionary landscape of light-harvesting complexes. She found a new variant shifted to the red that allows purple bacteria to grow faster under high intensity light www.biorxiv.org/content/10.1...

Directed evolution and characterisation of light harvesting complexes with altered energy transfer dynamics in purple non-sulfur bacteria

Purple non-sulfur bacteria (PNSB) are metabolically versatile microorganisms that inhabit diverse environments taking advantage of a remarkably efficient photosynthetic machinery. In this work, we des...

Genetic controllers for enhancing the evolutionary longevity of synthetic gene circuits in bacteria

Genetic controllers for enhancing the evolutionary longevity of synthetic gene circuits in bacteria - Nature Communications

Engineered gene circuits often degrade over time due to mutation and selection. Here the authors use a host-aware modelling framework to develop genetic controllers to sustain synthetic gene expression. They identify a range of design trade-offs in production, robustness and long-term performance.

A bit of an awkward request but hoping that someone can help. We are desperately looking for a vial of CHO-S cells that we could use. Ideally in the London area. Thanks!

Ok, to be precise (thanks @marcsdionne.bsky.social), they are considering implementing triage

Jose Jimenez @jjimenez.bsky.social · 28d

BBSRC to implement triage of proposals pre-panel and rolling deadlines to reduce assessment burden. Interesting times ahead!

Jose Jimenez @jjimenez.bsky.social · 28d

It would certainly help panel members, but for applicants would be key to know what their senior management will do if their proposals happen to end in the unfundable tier.

Well, JeS is no longer in use (for better or worse) so maybe it's time to suggest this again?

Appealing to the wisdom of the crowd: Let's say molecule X produced by microbe Y is used as an 'organic' fertiliser. If molecule X is produced recombinantly in microbe Z, purified and used as a fertiliser, could this process receive 'organic certification'?
