This week, the National Science Foundation announced the award of a six-year, $22M grant to UC Santa Barbara under its biofoundries program for the establishment of the BioFoundry for Extreme and Exceptional Fungi, Archaea and Bacteria (Ex-FAB), a collaboration led by UC Santa Barbara (UCSB), together with UC Riverside (UCR), and Cal Poly Pomona (CPP). The NSF Ex-FAB BioFoundry establishes the nation’s first biofoundry that focuses on largely untapped and unexplored extreme microbes. UCSB’s award is one of only five grants made under NSF’s BioFoundry program during this funding cycle, which awarded a total of $75M to the five selected universities.
“Our campus is thrilled to receive this visionary funding from the National Science Foundation, which reflects the research strength and innovation of our colleagues who are working across disciplines and institutions to advance biotechnology and bioengineering,” said UCSB Chancellor Henry T. Yang. “We congratulate Professor O’Malley and our entire campus team, and thank Michelle for her leadership of this pioneering effort. Our campus is known for our culture of working collaboratively at the cutting edge, and we look forward with great anticipation to the discoveries that will be made through the BioFoundry as our colleagues explore new frontiers in the world of extreme microbes.”
“We are extremely excited because this funding enables us to build infrastructure that nobody, especially in academia, has had access to before,” said the new center’s director Michelle O’Malley, a professor of chemical engineering and bioengineering at UCSB. “The facility allows us to unlock the promise of a new generation of synthetic biology — one that focuses on developing new biotechnology from extreme and unusual microorganisms found in nature.”
The research center will focus on developing techniques to learn from nature’s more unusual microorganisms, referred to as “extreme” in that they do not conform to standard growth habits and culture conditions in a lab. They may have unusual nutritional requirements, grow at extremely high or low temperatures, and even grow without oxygen, all of which makes them difficult to study with existing laboratory equipment.
“These extreme microorganisms defy our current understanding of biology, yet they often host traits that we want to harness for biotechnology – such as enzymes that chew up waste, or pathways that make valuable products and new medicines. Now, users have a place to bring their ‘weird’ microbes to study them and prototype new biotechnology from what they learn,” said O’Malley, who is a leading expert in engineering anaerobes to turn waste into more sustainable fuel, chemical, or bio-based materials.
While countless advances have occurred in synthetic biology, which involves engineering nature’s “parts,” such as DNA, proteins, and even entire organisms, to have new functions, the field has focused on microorganisms that are easy to grow, domesticate, and proliferate under standard laboratory conditions. Yet, domesticated microbes are often devoid of the traits that researchers want to exploit most for biotechnology. The most successful biological products in nature are built almost entirely by unusual microorganisms that have unique growth habits and are unwieldy. To unlock the power of extreme microbes, the center will tap into synthetic biology by designing first-of-its-kind instrumentation, novel robotic workflows, and technology powered by machine learning.
The NSF Ex-FAB BioFoundry will focus its efforts on three research themes — bioremediation, biosynthesis, and rules of life — to design microbes that can address environmental challenges such as the clean-up of PFAS (per- and polyfluoroalkyl substances) and other “forever chemicals,” the sustainable production of silica-based materials, the recycling and reuse of carbon materials, and the promotion of productive carbon and nitrogen cycles in soil and marine habitats.
“UCSB is a world leader in promoting multidisciplinary, center-level science,” said Umesh Mishra, dean of the UCSB College of Engineering. “We are extremely proud to host the NSF Ex-FAB BioFoundry, because it unites several strengths across our campus for the first time – from marine science to chemical engineering and bioengineering. This sizeable award by NSF raises the profile of our campus and serves as a focal point for continued investment in biotechnology and bioengineering at UCSB.”
“This new research center provides an exciting opportunity to open synthetic biology to the vast diversity of microbes that nature provides,” added co-director Ian Wheeldon, a chemical environmental engineering professor at UCR, who is an expert in synthetic biology and engineering non-conventional microbes. “The current focus of synthetic biology has been to develop new approaches to engineering a small number of commonly used microbes. This facility will dramatically broaden this approach by enabling synthetic biology in any microbe.”
