Vincent, Dickson, and Daniel solve their fishy tale, and present a new case study for your consumption.
It's true that I adore microbiology, and I am lucky to teach it each year to my micronauts. So it was time to commit. Here is my second "Microbial Supremacy" tattoo! The artwork is by Peggy Muddles (http://www.redbubble.com/people/thevexedmuddler/works/15659350-microbial-badass-tattoo-full-co... Read More

E. coli was grown on MacConkey Agar (MAC) at 37 degrees for 24 hour. MAC is a Selective and Differential media used to inhibit G+ growth and some G- bacteria as well as identify and isolate lactose fermenting G- enteric bacteria mainly Enterobacteriaceae. Strong lactose fermentation produces pi... Read More
Serratia marcescens can form brilliant red colonies on LB agar due to the synthesis of the secondary metabolite prodigiosin. In the Microbiology teaching lab, we had students create pigment mutants of S. marcescens and these lovely shades of pink and white were collected for analysis. Read More
