Organisms grown in Fluid Thioglycollate Media w/out resazurin dye is a reducing media that uses sodium thioglycollate to chemically combine with dissolved oxygen to deplete the oxygen in the media. All organism except for Neisseria sicca were grown for 48 hours at 37 degrees C. Neisseria sicca i... 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

Most mushrooms actually do not produce the visible fruiting bodies known to us as boletus, champignons, or toadstools. Many fungal species are the familiar “mold” and other unappetizing films, or are completely unknown to us. Here, you can discover some of the remarkable shapes and lifestyles of... Read More
