Bacteria Make Up Much of the Composition of the Soil

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

This organism is commonly found in soil and water, and is also associated with spoiled food. It produces a diffusible fluorescent pigment.

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

Used for culturing Dictyostelium discoideum (cellular slime mold). 

Isolated from milk and udders of cows. Lancefield group B, beta hemolysis. Causes infection of the female genital tract, maternal septicemia, neonatal infections. Camp test positive; resistant to bacitracin.

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

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

Taking their name from the bluish pigment that most of these organisms share, each jar contains a broad sample of several types of cyanobacteria.

Isolated from milk products; used in the manufacture of yogurt, buttermilk, and cheese. 

Isolated from milk, ferments lactose. Lancefield group N, gamma hemolysis

Azotobacter vinelandii is an aerobic organism normally found in soil, and is commonly known for its ability to fix nitrogen, converting it to ammonia.

All microbial cultures undergo an extensive quality control program prior to releasing for sale, so they are guaranteed for purity as well as for species.

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).
