$500,000 endowment will support UGA Extension entomologist Daniel Suiter as Orkin Professor of Urban Entomology

Dan Suiter, University of Georgia Cooperative Extension entomologist and well-known expert in addressing the needs of pest control operators, has been named the Orkin Professor of Urban Entomology at the University of Georgia.

Orkin, an industry leader in pest control services and protection, has created the endowment to help strengthen the entomology program in the UGA College of Agricultural and Environmental Sciences (CAES).

By supporting the CAES Department of Entomology, Orkin is supporting science that delivers transformative research to the world and helping to ensure that UGA faculty in urban entomology are leaders in their field. Orkin’s professorship paves the way for new research partnerships that advance the pest control industry, create new businesses and generate new jobs.

The World Health Organization estimates that there are 600 million cases of foodborne illness every year. One way harmful pathogens can enter the food supply is through irrigation water, but researchers are using precision agriculture to create a cost-effective and environmentally friendly way to combat the bacteria that makes us sick. And the tool they are using is available to everyone — the sun.

In recent years, researchers have begun to examine the effects of light on microorganisms. Antimicrobial blue light is used in hospital settings to reduce pathogens, and current research is underway at the University of Georgia to determine the viability of its use in food production.

UGA College of Agricultural and Environmental Sciences Professor Govindaraj Dev Kumar, who has been involved with those studies, is also the lead researcher on a recent study to determine sunlight’s ability to affect the survival of certain bacteria in water.

Food technology entrepreneur James Gratzek will serve as the next director of the Food Product Innovation and Commercialization Center (FoodPIC) on the University of Georgia Griffin campus, according to the Department of Food Science and Technology at the College of Agricultural and Environmental Sciences (CAES). Gratzek will begin his new role July 1.

Gratzek comes to FoodPIC from Food Physics USA, a food technology start-up focused on sales and applications for pulsed electric field technology — a way to preserve food using short pulses of electricity — where he served as technical and business development director.

Gratzek also founded Gratzek Food Technology, a Minneapolis-based food technology consulting company.

According to Manpreet Singh, food science and technology department head, Gratzek has been a leader in the food industry for more than 25 years. During his career, Gratzek has served as director of aseptic technology (a food processing technique) and project applications with TetraPak; director of innovation, technology and quality with General Mills; and senior vice president for research, quality and innovation with Sunopta Inc.

Researchers from the University of Georgia’s Center for Food Safety have developed software that functions as an important step in improving the accuracy of DNA sequence analysis when testing for microbial contamination.

Sepia is a cutting-edge read classifier, written by College of Agricultural and Environmental Sciences Assistant Professor Henk den Bakker, that is out now as open-source software. And it should make genome sequencing much faster for researchers studying bacteria.

The length of chromosomes of bacteria typically range between 1.5 million base pairs to roughly 9.5 million base pairs, but if researchers want to “read” the individual bases of a genome (the genome sequencing process), they can only do that in pieces of 150 to 10,000 base pairs using modern technology. These pieces are called “reads.”

Any time you walk through a park, play a recreation-league soccer game or enjoy an afternoon on the golf course, you are using the products of the multibillion-dollar turfgrass industry. In Georgia alone, turfgrass covers 1.8 million acres, making it one of the largest agricultural commodities in the state, employing more than 100,000 people with a maintenance value of $1.56 billion.  

Despite its economic importance, turfgrass researchers often face a lack of research infrastructure and facilities to conduct Extension and educational activities. That is no longer the case at the University of Georgia Griffin campus, where industry-funded partnerships have led to the installation of a research golf green and a research and Extension soccer field.

While the old song “Tiny Bubbles” lauds the happy effervescence of a glass of sparkling wine, new University of Georgia research on nanobubbles seeks to discover whether the tiniest of bubbles can hold beneficial properties for turfgrass.

Led by soil microbiologist Mussie Habteselassie, the Georgia Department of Agriculture-sponsored study will evaluate the potential applications of nanobubble technology to control pathogens and improve plant growth, water use efficiency and soil biological health in turfgrass systems. Other researchers on the project include turfgrass and forage pathologist Bochra Bahri and crop and soil scientist David Jespersen, all with the College of Agricultural and Environmental Sciences.

Using technology that generates oxygenated nanobubbles — which are roughly 2500 times smaller than a grain of salt — researchers will apply nano-charged water to turfgrass root systems through irrigation.

University of Georgia professors Scott NeSmith, Anumantha Kanthasamy and S. Edward Law have been elected Fellows of the National Academy of Inventors. Including these three new Fellows, 12 UGA faculty have received this honor, all of them since 2013.

NAI Fellows must be involved in creating or facilitating inventions that make a tangible impact on quality of life, economic development and welfare of society. Becoming an NAI Fellow is the highest professional distinction awarded solely to academic inventors. According to the organization, $3 trillion in revenue has been generated based on NAI Fellow discoveries. NAI Fellows’ research and entrepreneurship have resulted in more than 42,700 issued U.S. patents, 13,000 licensed technologies and 3,200 new companies — not to mention more than 1 million jobs created, according to NAI.

“As a National Academy of Inventors (NAI) director and Fellow, I am thrilled to welcome our newly elected Fellows to the NAI,” said Karen Burg, UGA vice president of research.

Congratulations are in order for UGA Griffin student, Darian Adams, for being named the recipient of the Marie Fort Garden Club Scholarship for 2021. The local club presents the $1,000 scholarship annually to a UGA Griffin undergraduate student in the College of Agricultural and Environmental Sciences (CAES). Adams was awarded the scholarship in October at a club meeting.

“Thank you so much,” said Adams to the club. “This scholarship will help me reach my career goals by helping fund my tuition and books. Getting a degree is my top priority and this scholarship will help tremendously.”

Getting up early on a Saturday morning to do physical labor is not necessarily every person’s idea of fun, especially when your bed is beckoning you to roll over for just five more minutes. However, that is exactly what a group of UGA Griffin students, along with faculty and staff, did on October 16 as they took part in the annual City of Griffin’s Stream Cleanup.

The Annual Stream Cleanup is a long-standing event that brings together citizens of Griffin-Spalding County to cleanup area streams and waterways. Volunteers remove trash and debris from their assigned stream in efforts to make their county a better and cleaner place.

“I think we were one of the largest groups who signed up to volunteer,” said Melissa Slaughter, a Center for Food Safety employee on the UGA Griffin campus. “I got involved because I used to help out when I was with 4-H and wanted to get the Griffin campus involved. It is a great way to give back to the community.”

When professional golfer Patrick Cantlay sank the birdie that won him the 2021 PGA TOUR Championship, he did it on turf that had been tested that morning by a student from the University of Georgia’s Griffin campus.

Ethan Barr, a junior and environmental resource science major at UGA-Griffin, scored a job assisting the PGA Tour with its culminating event of the season during the first weekend in September at East Lake Golf Club in Atlanta.

Barr's task was simple, but it had a significant impact on the tournament's outcome and reinforced his chosen field of study.

“We would go up early in the mornings to test how firm the greens are with a tool called TruFirm. It has a sensor on the end that you drop on the green and it tests how firm the greens are. You give those results to the person in charge of the golf course, and they make changes in the afternoon to make it firmer or less firm,” Barr said. “The head guy at the golf course said they want to make the greens challenging, but fair and consistent with regard to speed and firmness. We helped with that.”
