Molecular Trait Evolution (MTE), a Nebraska-based biotechnology startup, is quietly building a future where agricultural waste can power communities and strengthen rural economies. Founded by University of Nebraska–Lincoln graduate Sean Carr, PhD, alongside UNL professors Dr. Paul Blum and Dr. Nicole Buan, the company’s mission is as ambitious as it is practical: translate cutting-edge microbiology research into bioenergy solutions that work at scale.
“Molecular Trait Evolution offers innovation in the use of non-model microbes for new biocatalysts and renewable products,” the company states on its website – mtebiotech.com.
A Problem Hiding in Plain Sight
Every year, agriculture generates billions of tons of plant waste that often goes unused. According to MTE, as much as 182 billion tons of unusable plant waste is produced annually worldwide (mtebiotech.com). Much of it ends up discarded or burned, missing its potential as a renewable feedstock.
At the same time, biofuel production faces a challenge: converting that waste into usable sugars requires punishingly harsh industrial conditions. High heat, corrosive chemicals, and time-consuming processing add costs that reduce the economic and environmental benefits of biofuels.
MTE believes nature already solved this problem. By studying microbes that thrive in Earth’s most extreme environments, from hot springs to acidic pools, the company has identified and engineered enzymes uniquely suited to biofuel’s toughest conditions.
How the Technology Works
Instead of forcing fragile enzymes to withstand industrial stress, MTE turns to organisms built for it.
“Generating biofuels and renewable chemicals from agricultural waste requires intense heat and acid to be converted into usable sugars for fermentation,” the company explains. “We use enzymes from organisms which thrive in hot acid to develop an inexpensive acid and thermostable enzyme cocktail to digest lignocellulose for biorefineries” – mtebiotech.com.
MTE’s flagship product, Extremase, is a proprietary enzyme blend that can dissolve stalks, husks, and fibers, releasing sugars and oils more efficiently than current industry solutions (mtebiotech.com).
With Extremase, a 100 million gallon ethanol plant could generate an extra one million gallons of cellulosic ethanol without additional feedstock (mtebiotech.com). That translates to more energy from the same crops, a smaller environmental footprint, and improved farm and fuel security.
Competing With Giants
The enzyme space is dominated by multinationals like DuPont and Novonesis, companies with sprawling product catalogs and vast distribution networks. But Carr says size is not everything.
“Our competitors are incredibly large companies with massive product catalogues,” he explains. “The team at MTE are experts in the kind of microbiology many people did not know exists, let alone that it was possible to engineer. We take a dedicated approach to treat each of our enzyme products with the kind of hands-on specialization you won’t ever see with the other players.”
This boutique approach, paired with deep academic expertise, allows MTE to design cocktails that are more potent, faster-acting, and functional under a wider range of conditions than anything else on the market. And crucially, they’re developed and produced in Nebraska.
Teaming Science With Entrepreneurship
Carr, who serves as President and CEO, manages day-to-day operations while also leading lab work at the company’s base on UNL’s Innovation Campus. His co-founders bring decades of academic and entrepreneurial experience.
- Dr. Nicole Buan, Professor of Biochemistry at UNL, is a widely published researcher and editorial leader in microbiology.
- Dr. Paul Blum, Professor of Microbiology, has helped launch other biotech ventures, including Neurocarrus, and brings hard-earned experience from the startup trenches.
Together, the trio combines 60+ years of expertise in microbial engineering (mtebiotech.com).
Early Stage, Big Vision
Currently in the seed stage, MTE is focused on building prototypes and securing partnerships for pilot testing. Moving from bench-scale experiments to full-scale trials remains a daunting challenge.
“The jump from bench scale testing to pilot level real world testing is a daunting task requiring time, manpower, and expensive equipment,” Carr acknowledges. “Finding a strategic partner you can trust to test your product at 40,000 times the scale it has been tested before is a huge endeavor.”
Despite these challenges, the long-term vision is bold: build a full enzyme production facility in Nebraska and set the gold standard for converting agricultural byproducts into sugars and oils.
If successful, MTE’s innovations could help solidify the United States as the global leader in ethanol production while reducing agricultural waste and advancing a circular bioeconomy.
Beyond Biofuels
While ethanol is the immediate target, MTE sees broader applications for its technology. Its microbial solutions are being developed for:
- Wastewater treatment: Increasing the speed and yield of anaerobic digestion, reducing costs for municipalities.
- Renewable energy: Engineering microbes to produce fuel from CO2 and other renewable carbon feedstocks.
- Designed microbial systems: Building custom microbial consortia for specialized industrial biosynthesis (mtebiotech.com).
Each application ties back to the company’s central philosophy: use nature’s toughest microbes to solve society’s toughest biological problems.
Building the Nebraska Bioeconomy
As global demand for agricultural products increases, so too does the amount of leftover biomass. By unlocking value from that waste, MTE hopes to generate new jobs in rural areas, reduce carbon footprints, and create co-products ranging from renewable plastics to biochar (mtebiotech.com).
“Biorefining from ag biomass can create additional value products from the biomass alongside biofuels, such as renewable plastics, pharmaceutical precursors, and biochar for soil improvement,” the company notes. – (mtebiotech.com)
The Road Ahead
Like any startup, MTE is navigating a path filled with uncertainty. Yet, its blend of world-class science, Nebraska grit, and a problem worth solving may be exactly what the energy transition needs.
Carr is candid about what the company requires most: guidance. “Inventors and early entrepreneurs have so much to learn because often business isn’t their main area of expertise, so having knowledgeable guides is worth its weight in gold,” he says.
With the right partners and support, Molecular Trait Evolution could help redefine how the world thinks about agricultural waste—transforming it from a liability into a foundation for cleaner, more sustainable energy.
