"Microbiology"

Students identify and quantify microbes in air, soil, water, or any surface.

This spore-forming, thermophilic organism is commonly used for germicidal and sporicidal testing due to its ability to withstand higher-than-normal temperatures.

Both of these strains of Serratia marcescens are colorless mutants when plated alone, but when grown together, they produce a red pigment.

No Lancefield group shown, alpha hemolysis. Bile solubility test positive, optochin sensitive. Causes pneumonia. 

All-purpose medium that supports the growth of a variety of microorganisms.

This species of Rhodospirillum is commonly isolated from stagnant water and mud. It is especially interesting because it produces a red pigment and is also capable of photosynthesis.

This organism is commonly isolated from soil, and depending upon the temperature of its environment, can produce a distinctive red pigment.

This organism is occasionally isolated from soil, but most frequently from smegma- a secretion from male and female genitalia.

Normal flora of respiratory tract. Beta-lactamase positive. Also known by the name Branhamella catarrhalis

This organism can be isolated from many human urinary tract infections, as well as polluted water and sewage. It is commonly identified by its distinctive grape-like smell (trimethylamine) or because it can turn the agar light green due to production of a blue pigment (pyocyanin).

A fun and safe way to bring STEM-based learning into the classroom.
