This Week in Microbiology is a podcast about unseen life on Earth hosted by Vincent Racaniello and friends. Following in the path of his successful shows 'This Week in Virology' (TWiV) and 'This Week in Parasitism' (TWiP), Racaniello and guests produce an informal yet informative conversation about microbes which is accessible to everyone, no matter what their science background.

272 272: Metabolism’s Got Rhythm Sept. 16, 2022

TWiM explores the activation of natural product synthesis using CRISPR interference in Streptomyces , and how light/dark and temperature cycling modulate Electron Flow in Pseudomonas aeruginosa biofilms.
