Welcome to the Mukhopadhyay group site! 

Some news from lab..

June 29th, 2021

Ankita’s cool study on the discovery of Viral Genomes from the circular plasmid sequence data is out in mSysems!



June 25th, 2021

A new review in Nature Microbiology Reviews with Jay Keasling and our close collaborators at JBEI and ABPDU.



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).



Nov 30th, 2020

The Daily Cal published a great article on our Pseudomonas putida study to require glucose use for indigoidine production!

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 Deepawita and Thomas for leading this paper, now out in Nat Comm.





August 13th 2020

Our paper on using the yeast Bar-seq library to study population dynamics during bioreactor cultivation is published. Congrats to  Maren, Mitch, and Deepanwita. Great collaboration with the ABPDU. Check out the OA paper.





July 2nd 2020

Our paper on microbe-microbe interactions is out in Frontiers. We found iron to play an important role in antagonistic interactions, by using P. putida as a proxy microbe. Congrats to Thomas and Robin and collaboration with Jenny Mortimer!





March 24th 2020

Our first paper in Stay-at-Home life. A review on methods to study response regulators of  Two component signaling systems. The paper is Open Access. We highlight the DAP-seq and DAP-chip methods developed in our group.




March 14th 2020

The day we left our labs for the shelter-in-place and then the stricter stay-at-home, as a response to COVID19. Many papers and proposals to write. And lots to pick up when we return.

Feb 24th 2020

Our study on a genome scale approach and implementation to engineer a P. putida strain that show high production reliably across scales in on BioRxiv

Feb 13th 2020

Our 2020 annual m-group offsite. At the Cal Faculty Club again. A fantastic day of discussing science, careers, kindness, building clay objects and failing at unentangling human knots!!










Jan 11th 2020

Megan gives a beautiful talk on swapped domains in response regulators at the GRS for Sensory Transduction in Microorganisms at Ventura Beach, CA





Nov 21 2019

Thomas Eng and Yusuke Sasaki showed that ceratin variation in the heterologous  isopentenol production pathway lead to the production of tetramethyl pyrazine – solely and upto 5g/L. TMP is famous for its use as a coffee flavoring! Open source in Metabolic Engineering Communications!









Nov 21 2019

Kudos to Ankita Kothari for showing that a putative mercury resistance operon present on an abundant 8-kbp native plasmid found in Oakridge ground waters encodes functional genes and that this plasmid can be taken up via natural competence by a range of isolates from this site! The paper is open access on mSystems.





Nov 21 2019

A very special day for our group. THREE papers accepted. One: Deepanwita and Aindrila co-authored a review led by Yan Chen and Chris Petzold on Systems biology methods and that’s accepted in Current Opinions in Biotechnology ! Thanks also to Deepanwita for supporting JBEI in our outreach activities (Nov 11th Biotechnology Celebration event on Saturday!)






Summer 2019: Conference season


We had a great summer of conferences! Thomas presented at the ECI conference, Ankita at the SEED conference Maren at the SIMB conference , Aindrila at Pseudomonas2019!  We heard some great talks, got awesome feedback and came back to the lab inspired!

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! Robin and Thomas make a great team and we have fantastic cross-disciplinary contributors this story from across LBNL and also from external collaborators. We found that microbial presence does impact how plants respond to exposure to many chemicals. Check out the paper! More studies to follow and all in collaboration with the Mortimer group!!
