JBEI annual meeting 2022
This year, JBEI held its annual retreat in Monterey, California. On the coast of the bay, we could learn more about the excellent work and updates of each division and the other Bioenergy Research Centers.
It was a very participative week for the group! Aindrila presented the Biofuels and Bioproducts Division talk session highlighting the objectives of FY23, Aparajitha talked about her work modifying bacteria for the production of Isoprenol and other products such as Tetramethylpyrazine using plant biomass, Shawn presented a poster about his work designing and optimizing a synthetic Isoprenol biosensor, and Deepanwita and Javier presented a poster about their work developing growth-coupling strategies for the production of the bio-pigment Indigoidine.
It was a great time to meet new people and to better understand the synergy of our work. Congratulations to the JBEI team for making it possible to enter phase 4!
October 28th, 2022
Today we say goodbye to a great researcher, Nicolas Gurdo! He visited us for 4 months from the Denmark Technical University where he is completing his PhD, and it has been a pleasure sharing lab, knowledge, and research with him. We hope you have a good trip back and that you will visit us soon!!
September 22nd, 2022
In the Science SLAM – Congratulations, Aparajitha Srinivasan!
Aparajitha has placed third in the 2022 Berkeley Lab Research SLAM. With a metaphor about how Google recalculates the estimated time of arrival, Aparajitha explained how her work in computational models is helping her to engineer microbes to produce sustainable products in the most efficient way.
If you want to know more, Checkout the Youtube link to the event recording. Sarah Gleeson (1st place), Mohammed Ombadi (2nd place), and Aparajitha will advance to the regional Bay Area Research SLAM!
M-group annual meeting 2022
To celebrate this year’s annual retreat, we decided to spend the day at Charles Lee Tilden Regional Park. We hiked the mountain with the smell of eucalyptus trees and views of the bay in the morning and finished with a picnic with a mix of international foods. It was a great way to spend the day as a team outside the lab and get some fresh air on the last day of summer, we will definitely do it again!
It’s raining Science at SFO
More the merrier
A modeler in every sense Research Scientist, Deepanwita Banerjee talks about her passion for modeling not just genomes but also miniature houses in this “Behind the Breakthrough” series of Berkeley Lab. Dee takes a trip down memory lane giving us a glimpse of her childhood spent in India and how it inspired her research career. We are in love with the cool doll-house she built from recycled items. Are you?
This month’s Midday Science Cafe menu – CRISPR, Blue dyes, and Biofuels
What happens when you heterologously express response regulators from one bacteria in another? How does the post-translational phosphorylation change? Is it even important to characterize the phosphorylation states upon heterologous expression? Read the full research article here. Congrats to Megan Garber, Anne Kakouridis and other collaborators on this publication!
April 28th, 2022
Congratulations to Kevin Lam, Angela Wei and Kevin Chen-Xiao!! It was great having undergraduate students with us at the lab again! On 4/28/22 they presented the work they had done in the lab in the last months, and as you can see in the picture, their mentors couldn’t be prouder! We hope you have a great well-deserved summer!
March 31st, 2022

Space traveling Cyanobacteria
Aindrila: Hey, What are you up to these days?
Random researcher in the group (RRIG) : Hi Aindrila! I am sending my samples for sequencing today.
Anne Kakouridis: I am sending my samples to SPACE.
RRIG : Wait, what?
Yup, you heard that right!
Anne and Aindrila, in collaboration with Rhodium Scientific and NASA are figuring out ways to transport DNA to space using Cyanobacteria as the model host. Cyanobacteria are fascinating organisms with valuable natural functions such as photosynthesis and viability under extreme conditions. Anne and Aindrila are using these features of cyanobacteria already present in nature to figure out ways to transport DNA to space more easily and reliably.
“In the first part of the project, we transformed simple plasmids into Nostoc punctiforme, desiccated the cultures, and transported them to the International Space Station (ISS) and back. In the second part of the project, we will attempt to revive the cyanobacteria and retrieve the plasmids we placed into them. We will then evaluate if there are any mutations or defects in the DNA to determine if conditions such as desiccation, microgravity, and radiation affected the DNA in situ. Our hope is that the DNA was preserved intact during desiccation and space travel. If this works – these cyanobacteria may become the carrier for DNA for space travel!”, says Anne.
Read the highlights of this work in the biosciences area news and on the ISS national lab website.

Of synthetic chemists, biologists and unnatural biosynthesis..
Check out this supercool study published in Nature Chemistry with our collaborators – Douglas Clark, Jay Keasling and John Hartwig. We demonstrate that marrying synthetic biology with synthetic chemistry can produce molecules that were previously inaccessible to nature, in engineered E. coli cells. Congrats to Jing who led this study! This work was also featured in Chemical and Engineering news and the Berkeley News.

May 6th, 2021
Deepanwita and Thomas lead another nice study where we show that a deletion in a response regulator GacA in P. putida results in greater fitness during bioreactor growth. This mutation also improved the production of Indigoidine from the non-sugar carbon source para-coumarate. Read our OA paper here!
March 11th, 2021
We had our 2021 annual m-group offsite virtually this year. It isn’t the same as spending a day together in person but it’s the next best thing! We had some really great activities! Hearty laughing at impromptu presentations, a great guess-who session, and even some meditation! The best part was welcoming new and yet to join group members who are onboarding during this difficult time.
(Zoom screen! Megan, Aindrila, Javier, Jeff, Shweta, Deepanwita, Jing, Thomas, Anne, Russel. Aparajitha and Alex).

Read it here Photo: Andrew, Thomas and Deepanwita
And Berkeley Lab IPO now has a link to the technology. See the Technology link here!
Oct 23th 2020
Product Substrate Pairing! This is great a start to what we hope are many more such systems to come. Being able to rewire metabolism to ensure that growth is coupled to the production of target compounds or their precursors allowed us to get the highest levels of indigoidine yet, in P. putida KT2440 from glucose. And the production shifted to an exponential phase. The nice production features held up in fed-batch and higher scales. Another collaboration with the ABPDU and JGI. Congrats to Deepanwita and Thomas for leading this paper, now out in Nat Comm.
August 13th 2020

May 29th 2019
We engineered a fungal host, R. toruloides and optimized production condition to get high titer production of a blue pigment Indigoidine. This compound is a non-ribosomal peptide. We are now exploring if R. toruloides is a good host for other NRPs – a large group of compounds ranging from commodity to fine chemicals. All this and sustainability!! Read Maren’s open access paper here!
May 15th 2019
Our first paper on examining the impact of “JBEI” chemicals on biological systems is out!
