While not original art, it’s still a fun piece. BBL’s CHROMagar Orientation agar is the canvas for this piece of agar art. Chromogens in the agar release a colored compound when hydrolyzed by specific enzymes allowing certain bacteria to appear different colors on it. The brown color is Proteus... Read More
Slime production by Staphylococcus epidermidis on Congo Red agar; demonstrated by black colored colonies. Slime production is one of the most important virulence factors produced by Coagulase negative Staphylococci.
The colonies of slime non-producing strains remain pink to red.
