A 糖心Vlog官方 Mānoa undergraduate who conducted a research project on her way to earning a bachelor of science degree in 2014 in was instrumental in the discovery of a spiral-shaped bacterium that is the only known representative of a new genus and species.
Vanessa K. Zepeda, 30, is the lead author of a paper published in the current issue of the . She worked with advisor Stuart Donachie, chair of the , on research that led to the discovery and cultivation of the bacterium named Terasakiispira papahanaumokuakeensis, which reflects its origin in the .

“The spiral-shaped bacterium grown from a pond on the Pearl and Hermes Atoll in the Northwestern Hawaiian Islands is the only known representative of a new genus and species,” explained Donachie. “The species is distinct from those in related genera because of the conditions it requires for growth, such as the presence of salt, its biochemical profile, and through the composition of its DNA. This discovery is another example of the novelty that occurs even among microbes in Hawaiʻi.”
The cells are spirals, and are quite unusual because they have flagella at each end. Flagella are what the cell uses to move. .
