Howe it’s done: unraveling environmental secrets for a better future
Guest: Dr. Adina Howe and Nicole Geerdes
Dr. Adina Howe’s research is a groundbreaking blend of molecular and computational biology, focused on unraveling the complexities of microbial systems in both natural and engineered settings. Her work explores various key areas, including the identification of microbes that drive biogeochemical cycles and their responses to climate change, understanding the roles of microbial genes and populations in ecosystem functions, and detecting biomarkers for environmental health like antibiotics and pathogens.
Much of her research also involves managing vast sequencing datasets through cutting-edge computational methods, utilizing high-throughput sequencing techniques to examine microbial community interactions, and advocating for sustainable practices in scientific data and software management.

In this experiment, a plasmid with a gene (DNA) for resistance to the antibiotic ampicillin and the lacZ gene will be transferred into a susceptible strain of the bacteria. The same technique is used to transfer genes (DNA) for the production of insulin, growth hormones, and other proteins into bacteria. The transformed bacteria are used in fermentation to produce commercial quantities of the protein for treating diabetes, dwarfism, or other uses. The cells that take up this plasmid will show resistance to the antibiotic and produce a color change (dark red) as the lacZ gene converts lactase in the media.
