From the PhD Lab: How do biofilms help keep bacteria alive? - with Josh Horton
Oct 14, 2026 · 26m
Summary
In this episode of "From the PhD Lab," Josh Halton, a molecular microbiology researcher at the Quadram Institute, explains how bacteria form protective biofilms that pose significant risks to food safety, citing the 2022 Kinder Surprise egg recall. He details his PhD work investigating the gene MALP in Salmonella, which regulates biofilm formation and antibiotic resistance, using techniques like TARDIS to identify its role in the complex regulatory pathway. Halton also discusses the potential for using biofilms in bioremediation to break down plastics and extract metals from chemical waste.…
