Team discovers potential bacterial solution to 'forever' chemicals

By Nebraska Today


A recent study led by researchers at the University of Nebraska-Lincoln, including DWFI Faculty Fellow Nirupam Aich, discovered that the common bacterium Rhodopseudomonas palustris has the potential to help break down "forever chemicals" known as PFAS. The team's work, published in "Environmental Science: Advances," showed that the bacterium absorbed a significant amount of the chemical PFOA into its cell membrane, demonstrating a biological interaction. While the chemical was later released from the cell, this finding establishes a critical foundation for further research. Dr. Aich and his collaborators are now planning follow-up studies to use microbial and synthetic biology to enhance the bacterium's ability to retain and potentially transform these persistent chemicals.

Collaboration Grows Success With Dry Bean Breed ‘Kikatiti’

By Chabella Guzman, PREEC communications


The new dry bean variety, 'Kikatiti,' is achieving success in East Africa thanks to a fruitful collaboration between DWFI Faculty Fellow Carlos Urrea, University of Nebraska–Lincoln Bean Breeder at the Panhandle Research Extension and Education Center in Scottsbluff, and Teshal Mamo of the Alliance of Bioversity C/AT. Urrea helped develop the pinto bean—a cross first made at the University of Nebraska in 2003—and noted its "exceptional performance" for its resilience to low soil fertility, high temperatures, and drought, along with its disease resistance and quick maturity. This collaborative effort, which also included Urrea's team training African scholars in breeding techniques, is now expanding the drought-tolerant bean's reach to regional nurseries in 10 African countries, aiming to improve nutrition, especially by providing iron and zinc to schoolchildren, and establishing a high-demand cash crop for farmers.
