University-Industry Partnership Leverages LSU Library of 11,000 Microbes for Bioremediation
In 2020, LSU licensed access to a vast library of bioremediation microbes to the national environmental services firm Cameron-Cole, LLC. The library was developed by Environmental Sciences Professor Emeritus Ralph Portier over almost 40 years as he and LSU helped private companies as well as local, state, and national government organizations mitigate a wide range of environmental hazards. After Portier’s passing in late 2021, Cameron-Cole continues to build on his legacy in Louisiana and across the globe.
BATON ROUGE, December 15, 2021 — After Ralph Portier’s recent passing, Jerome Edwards, president of Cameron-Cole, LLC, an ADEC Innovation company, expressed his continued commitment to work in partnership
with LSU to build on the scientist’s legacy:
“With 30 active remediation projects, including a number in Louisiana, we continue
to use Ralph’s platform as an opportunity to grow and develop new technologies. Cameron-Cole,
our clients, and LSU have demonstrated time and time again that we are committed to
preserving and broadening access to Ralph’s lifelong work of using proprietary targeted
microbial applications to transform specific contaminants into harmless compounds.
These are challenging problems that we’re working to solve, and Cameron-Cole’s clients
rely on us for answers they can’t find from other environmental consulting companies.
Ralph was a true pioneer in microbe technology, and as we recently merged with a global
organization, ADEC Innovations, his work is starting to get further traction as a viable, scalable solution to heal
the planet.”
BATON ROUGE, July 30, 2020 — LSU has licensed access to a vast library of bioremediation microbes to the national
environmental services firm Cameron-Cole. The company has previously been working
with LSU scientists on specific projects for multiple clients in the manufacturing,
petrochemical, construction, waste management, and military industries for over a
decade. Much of that work has been sourced from the 11,000-organism-strong bioremediation
library Environmental Sciences Professor Emeritus Ralph Portier developed over almost
40 years as he and LSU have helped private companies as well as local, state, and
national government organizations mitigate a wide range of environmental hazards in
the U.S. and across the globe. Now, Cameron-Cole will have a valuable resource at
its fingertips to help its own clients.
Microbes can be used to break down dangerous chemicals and pollutants, including fuels,
plastics, herbicides, and pesticides. For most of his career, Portier—an expert on
ecotoxicology and bioremediation—designed custom bioreactors to do just that, ranging
in size from something close to an ink pen to tanks as tall as four-story buildings.
Bioreactors (microbial habitats, if you will) are filled with bio-beads covered with
specific microorganisms and the round shape of the bio-beads allows for some empty
space in between them. Next, polluted water is pumped in and the microbes get to work
degrading and breaking down the contaminants. Of course, only certain microorganisms
are able to “eat” certain chemical compounds. Over the years, Portier and his LSU
team identified new microbes and figured out which would be the best match to also
keep each bioreactor more or less self-sustaining over time. In some cases, Portier
and his team would chain different bioreactors together to perform complex remediation
tasks more efficiently.
“Microbes are lazy,” Portier said. “They chew up the easy stuff first. The reason
you don’t find sucrose or glucose loose on the planet is because microbes have eaten
it. When you design a bioreactor, you have to make sure the system doesn’t lose its
genetic signature because you gave them something too easy to eat. If there are complicated
compounds to break down, you might have to chain bioreactors together so the microbes
in the last one don’t have the choice to derive energy from simpler sources. If you
can figure that out, the only question that remains is how long and how fast you can
pump the water through.”
The best possible outcome from each system would be polluted water going in and clean
water going out, along with carbon dioxide and some harmless biomass. The better the
match, the cleaner the water. But Portier did not only work on wastewater and ground
water, he worked on soil and sediments, too, helping companies in Louisiana and throughout
the world conduct their businesses more sustainably and avoid potentially bad reputations
and costly fines.
“As companies want to be green and pro-environmental, you have to remember there’s
another green involved here too, and that’s money,” Portier said. “There is a huge
business incentive to this as well, because a good environmental policy is a good
economic policy. It costs a lot of money to be in violation of the federal guidelines,
and companies can’t afford to lose their permits.”
“Also, a lot of these large industrial and chemical plants that we have down here
in Louisiana bring great value to our state,” Portier continued. “Jobs are important,
and if we can help some of these companies solve possible environmental problems so
they can stay here and expand, that’s great for Louisiana. Plus, they hire my students!”
In his work at LSU, Portier helped shape policies and processes for the Environmental
Protection Agency, or EPA. To date, some 265 sites across the country and 12 international
sites have been successfully remediated using LSU biotechnology patents and intellectual
property developed by Portier. Some of the projects he’s been involved in include
the cleanup of an oil refinery in Ascension Parish, Louisiana; a creosote wood treatment
factory in Baldwin, Florida; an army ammunition plant in Karnack, Texas; and a wool
scouring mill in Yorkshire, England.
With the licensing of Portier’s technology to Cameron-Cole and potentially other industry
partners, LSU is able to share knowledge that was primarily developed in university
labs to have a greater impact everywhere.
“This agreement will enable us to work even more closely with LSU’s core resources
to expand our bioremediation capabilities,” Tim Hobbs, Cameron-Cole’s COO and principal
hydrogeologist, said. “These microorganisms have proven to be effective on hydrocarbon
fuels, chlorinated hydrocarbons, and pesticides/herbicides, transforming them into
harmless compounds.”
“It’s a good legacy to have; to have gone places and left them in a better shape than how you found them.”—Ralph Portier
Cameron-Cole President Jerome Edwards remarked on the value of his company’s long-term
collaboration with LSU and continued access to university research expertise in microbiology.
“It has been inspiring to work with Professor Portier,” Edwards said. “His creative
problem-solving is contagious and has led our consulting professionals to identify
opportunities for LSU’s team to develop new approaches to previously unsolvable situations.
We knew we had done our job well when he would say, ‘Why don’t you bring me an easy contaminant sometime, and not all of these difficult ones?’”
One can think of Portier’s library as a collection of microorganisms and preferred
recipes Cameron-Cole can use to design unique microbial communities to help their
clients manage industrial and petrochemical waste before it becomes “pollution.”
“For implementation, university researchers like me need companies like Cameron-Cole,”
Portier said. “Our work at LSU—we would make an initial evaluation, develop a work
plan, conduct a lab feasibility study, then a field pilot, and finally do a field
implementation. Most of our work was in coming up with the know-how and figuring out
solutions, doing pilot studies showing how bioremediation can be done. For wide-scale
implementation, however, universities must partner with industry and government. We
can show them how to do it and that it can be done, but they have to take the lead
with the technology.”
The licensing of Portier’s library fits well into LSU’s overall mission to share knowledge
and resources developed at the university with private industry as well as the general
public.
“Portier has made foundational contributions to bioremediation research at LSU, in
Louisiana, and across the nation for nearly four decades,” Vice President of Research
& Economic Development Sam Bentley said. “We are grateful for his leadership in this
field and proud of the worldwide impact of his work.”
Portier emphasized that bioremediation is good business and an easy “sell” for most
private companies.
“Bioremediation is an attractive approach because you’re using a decomposer and the
natural carbon cycle to clean something up,” Portier said. “Remember, hazardous waste
is just carbon in the wrong form and in the wrong place. Some things that are problems
in one place can be solutions in another.”
During his career, Portier helped remediate several so-called Superfund and RCRA sites,
which are designated by the EPA as toxic and in need of cleanup. In Devil’s Swamp,
miles north of Baton Rouge—“a horrible site”—Portier found a microbe in the soil that
turned out to be so useful for breaking down chlorinated phenolics and chlorinated
benzenes (common in herbicides and pesticides and ubiquitously found in ground water)
that he named it LSU-101. He later used it in the design of several bioreactors and
other remediation projects.
“Based on field samples, we’ve been able to create custom solutions in the lab, including
for the same contaminant in different areas,” Portier said. “If we had pesticides
running off a sugarcane field in St. James Parish and the chemicals made it all the
way to Grand Isle, we could simulate both scenarios in the lab with different groups
of organisms and figure out how to help in both places.”
“It’s a good legacy to have,” he concluded. “To have gone places and left them in
a better shape than how you found them.”
