Construction and comparison of different vehicles for heterologous gene expression in Zymomonas mobilis
In this study, a series of shuttle vectors compatible with modular cloning were constructed based on the replication mechanisms of the native Z. mobilis plasmids pZMO1, pZMOB04, pZMOB05, pZMOB06, pZM...

I'm assembling a denovo genome of a new pseudomonadota (ONT r10), and barrnap is consistently unable to resolve the 5S site(s) from what should be a fully circularized and decently polished output. Based on the 16S and 23S hits there should at least be 3 5S.
What could be happening here? 🤔

Very happy to share our recent work @cultivarium.bsky.social on genetic tools for Ideonella sakaiensis, a (Betaproteo-)bacterium that degrades PET plastic.
We identified a plasmid vector for the strain and generated a large RB-TnSeq library, screening for genes impacting plastic degradation.

#Lichens form their complex thalli through a partnership involving at least a fungus and an alga. But can these living structures be rebuilt in vitro? For more than a century, people have tried. With @spribille.bsky.social we revisited 150 years of #lichen #resynthesis to ask: has anyone succeeded?

Absolutely the way to fix peer review is for peer reviewers to do better reviews, not an AI to almost match the current poor level of human review. But maybe if you take away the oppotunity for humans to point out a axis label is missing, they'll find more interesting things to say?

Scientists often engineer microbes, like E. coli, to make drugs and other molecules.
But what if, instead, we could isolate ALL the components of a cell into little vials and sell them? How much would, say, 1 liter of cells be worth?
The answer, it turns out, is about $600,000.
