Researchers at the University of Arkansas have developed a method to simplify the pharmaceutical production of proteins used in drugs that treat a variety of diseases and health conditions, including diabetes, cancer, arthritis and macular degeneration.
With assistance from the National Science Foundation Innovation Corps program, Ellen Brune, primary researcher and inventor of the technology, has started a company to shorten development time so that new drugs can get to patients faster. Current protein pharmaceutical development is a complicated, time-consuming and expensive process because manufacturers must separate and extract contaminant proteins.
Brune, a doctoral student in chemical engineering, created a series of custom strains of the bacteria Escherichia coli that express minimized sets of contaminants or “nuisance” proteins. Brune then sought assistance to commercialize the technology. In an entrepreneurship class taught by Carol Reeves, associate vice provost for entrepreneurship and management professor in the Sam M. Walton College of Business, Brune created Boston Mountain Biotech LLC, a research and biotechnology firm that will save significant time by preparing the proteins for the manufacturing process.
“Millions of people across the globe are suffering from treatable diseases because manufacturers cannot afford to make the drugs they need,” Brune said. “These companies have to spend too much time and money getting rid of stuff that doesn’t work to get to the stuff that does. Our work addresses this problem. Our cell lines reduce the garbage, so to speak, before the manufacturing process begins.”
Current protein pharmaceutical manufacturing involves separating or cleaning up “background” contamination to reach the target protein – a long and expensive process. Background contamination is undesirable and unnecessary proteins that are prohibited by the U.S. Food and Drug Administration in the final drug product. The FDA requires that the final product be 99 percent pure.
Drug companies spend roughly $8 billion a year trying to clean up these contaminants during production. Brune compares the process to making orange juice by blending the peel and seeds along with the meat of an orange. Once the juice is made, producers would then have to filter out the chunks of seeds and peel.
In the laboratory, Brune worked under the direction of chemical engineering professor Bob Beitle, one of several researchers who have been investigating this problem for more than a decade. Brune designed custom strains of “Lotus” E. coli. Lotus refers to a suite of cell lines optimized to work with specific separation techniques and characteristics. She accomplished this through bio-separation and genetic manipulation, specifically by removing the sections of DNA that code for the contaminant regions. Her work simplifies the purification process on the front end of protein pharmaceutical production, so that the cell line is specifically developed for manufacturing. Current cell lines used for protein production look nothing like what has to be achieved for large-scale manufacturing, Brune said.
Brune serves as chief scientific officer at Boston Mountain Biotech. In addition to the assistance from Reeves and the entrepreneurship program, the company has received significant support from the NSF I-Corps Program, including $50,000 in marketing and operational funding and participation in an innovative, start-up training program that provided a foundation for connecting with potential investors. Boston Mountain Biotech has also won a total of $50,000 from business plan competitions, mostly due to Brune’s persuasive presentation skills. The company is seeking additional investors and is currently working with two manufacturers on pilot testing.
Brune has produced two videos about the company, an informational video for the I-Corps grant and a second video intended for investors.
NSF I-Corps is a set of activities and programs that prepare scientists and engineers to extend their focus beyond the laboratory. The primary goal of the program is to foster entrepreneurship that will lead to the commercialization of technology that has been supported previously by NSF-funded research.
Since 2006, the Walton College entrepreneurship program, which Reeves directs, has produced six companies that employ more than 100 people, most of whom work and live in Arkansas. The college offers a Master of Business Administration with an emphasis in entrepreneurship and a certificate in the same for graduate students, such as Brune, in other colleges and schools. Reeves has served as director of the program since its inception in 2006 and has mentored business-plan teams in competitions since 2002. Brune won first place in the graduate competition of this year’s Donald W. Reynolds Governor’s Cup, Arkansas’ largest business plan competition.

Chemical Engineering Students Design Award-Winning Microhydro Power Generator
Under the mentorship of Prof. Roy Penney, two chemical engineering studentdesign teams competed at the 2012 WERC Environmental Design Contest at New Mexico State University in Las Cruces on April 1-4. Roberto Arraya, Aaron Hughes, Travis Rose, and Nathan McAlister won first place and $2,500 for Task 6 - Microhydro Power Generation, for their design which used a turbine to produce electric power from a waster water stream. Teams competing in this task were charged with developing a pilot system that determines whether industrial wastewater can be used to create hydroelectric power. The pilot system was required to create a minimum of 10kW but also create a positive return on investment within a five-year period. The University of Arkansas team was able to produce 40kW of electrical power usinga 3.5 million gallon/day and 120-feet head wastewater stream from Intel's Rio Ranch, New Mexico plant.
Elizabeth Fullerton, Andrew Gibson, Carianne Reed, Tony Smith and Anne Ziegler competed against nine other teams in Task 5 - Green RO Pretreatment, which required teams to develop and demonstrate an alternative to disposable filters or an improved disposable filter design that can last at least four months filtering somewhat turbid feed water. To increase the life of reverse osmosis (RO) membranes, processes from each team should ideally address particle size down to 0.1 microns to account for suspended solids that cannot pass through current cartridge filters, and thus foul RO membranes. Their students' design improved the microfiltration system used by the U.S. Navy to improve the pre-filtering process of ocean water to feed reverse osmosis systems on Navy ships.
WERC is a consortium of agencies, companies and academic partners that try to address environmental education and technology development needs. The consortium is based at New Mexico State University. WERC conducts an annual contest among student teams that design solutions for environmental problems.

Chemical engineering associate professor Keith Roper and his colleagues at the University of Utah have discovered a new method of making nanoparticles and nanofilms to be used in developing better electronic devices, biosensors and certain types of high-powered and highly specific microscopes used for scientific research.
Nanoparticles – far too small for the human eye to detect – make up the building blocks of the latest processing hardware. The researchers’ nanoparticles, made of gold and deposited onto silicon substrates by a unique chemical process, are nontoxic and inexpensive to make and have superior dimensions, densities and distribution when compared to other nanoparticles and conventional methods of producing nanoparticles. The unique deposition technique has the further advantage of being able to rapidly coat fragile, three-dimensional and internal surfaces at the temperature and pressure of its surroundings without requiring conductive substrates or expensive, sophisticated equipment.
This unique approach improves upon a method that involves depositing atoms from a solution onto a substrate with a tin-sensitized surface. The researchers use a novel continuous-deposition process and then heat these deposited atoms to transform “islands” of nanoparticle material into desired forms. Ultrathin films prepared by this new approach are smoother than conventional “sputtered” or evaporated gold films and may exhibit better optical features, such as reduced surface-roughness scattering. These features are desirable in devices such as photovoltaic cells in which narrow metal layers significantly affect local electromagnetic fields. Smoother thin films could also improve the limits of detection, sensitivity, and photocurrent, respectively, in such applications.
The researchers were awarded U.S. Patent No. 8,097,295 on Jan. 17 for the development.

“Mixing is getting to be a lost art,” explained Roy Penney, professor of chemical engineering at the University of Arkansas. While the blending of fluids is still critical to the chemical industry, most current academic research focuses on topics like nanoscience, biological science and biomedical science.
Penney still teaches students and practicing engineers this important skill in his AIChE industrial fluid mixing course, and the North American Mixing Forum, an affiliate of the American Institute of Chemical Engineers, recently recognized his contribution to the mixing field with the Award for Excellence and Sustained Contributions to Mixing Research and Practice.
One of Penney’s most important achievements in industrial mixing research and development was leading the engineering effort at the A.E. Staley Manufacturing Co. and the German company Henkel Co. to design a chemical reactor system to mix and react dextrose, a sugar made from corn, with fatty alcohol from palm oil to produce alkyl polyglocoside. This chemical, which is made from natural, renewable resources, is an important ingredient in personal care products like hand soap and shampoo.
Reacting the two ingredients that make up alkyl polyglocoside requires a strong acid catalyst, and when the reaction is complete, the catalyst must be neutralized quickly using sodium hydroxide.
“You must have very good and fast blending when you introduce the sodium hydroxide,” said Penney, “or the dextrose will degrade in the presence of strong caustic.” The reactor system designed by the Staley Engineering Team is currently in use by Henkel, at plants in Cincinnati, Ohio, and Dusseldorf, Germany. Henkel uses the alkyl polyglocoside in its products, including Dial soaps, and sells it to other companies such as Procter and Gamble.
AIChE has also named Penney a Fellow for his contributions to the organization and to the chemical engineering profession. He has been a member of the AIChE student contest problem subcommittee, which develops and grades problems for undergraduate contests, and he is theauthor of the 2012 AIChE Contest Problem, “The Production of non-Alcoholic Beer from Alcoholic Beer by use of Membranes." Penney was chair of the Contest Problem subcommittee from 1995 to 2003, and he was chair of programming for the North American Mixing Forum from 1989 to 1995.
