How to direct #carbon traffic at junction of different pathways? Our paper in PNAS @PNASNews shows how #Pseudomonas #bacteria use two versions of same enzyme. Collabs with @NorthwesternEng Niall Mangan @DTUBiosustain @PabloINik Adam Guss @doescience Jake Waldbauer Lab @UChicago

A team led by Professor Ludmilla Aristilde found that two versions of one enzyme act as “traffic controllers” for carbon in bacteria — a discovery that could help engineers turn waste like plant matter or plastics into useful chemicals and fuels.

That was so much…we discussed different research topics covered by the @AristildeLab
@AristildeLab joins Nanoscape to discuss how microbes and minerals work together to recycle waste, nutrients, and even plastics. Hear how her nanoscale discoveries are helping shape the future of sustainability.

How do soil bacteria balance energy metabolism with carbon #metabolism in using #lignin carbons? Check out our @CommsBio article on how we figure out the "traffic jams" and "stoplights" in Pseudomonas metabolic reactions in lignin carbon conversion. Link: nature.com/articles/s42003-0…

Many years ago, I decided to follow in the footsteps of my parents who were both educators: my mother, a kindergarten teacher; my father, a school principal. I so wish they were both still around to celebrate this milestone!

Growing up in Haiti, my love of science started from being curious about how do soils make plant grow. Now, my research group studies the molecular chemistry and biochemistry of minerals and bacteria from soils that benefit agriculture, biotechnology, and sustainability.

In this period of uncertainty, the University will fund research that is subject to stop-work orders or the federal funding freeze, President Schill and Board of Trustees Chair Peter Barris announced today.

#Pseudomonas putida preprint alert: We provide a quantitative blueprint of #carbon and #energy fluxes in the native metabolism of #lignin aromatics: ferulate, coumarate, vanillate, and hydroxybenzoate.

Concrete is a climate problem, and this breakthrough could help fix it.
Professors Alessandro Rotta Loria and Jeffrey Lopez have developed a carbon-negative material that makes cement and concrete more sustainable without compromising strength.

A worthy read!

Today I’m joining 30 colleagues in taking an unusual step: calling for a halt to a line of research I was excited about, the long-term effort to build “mirror life”.
We’re sharing our findings in a @ScienceMagazine paper:

Check out live interview @WGNNews #Chicago on the 5'Oclock news today. We discussed the plastic problem and @Aristildelab research on figuring out how microbes in #nature can feed on #plastics...a slow process that could be engineered to benefit #society.
