"bacteria"

Isolated from soil. Forms red pigment (best on high carbohydrate medium) and has oval eccentric spores. 

Isolated from sewage, human intestines, and urinary tract infections. Spreading colonies are seen on agar growth medium. 

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.

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

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

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.

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

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.

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

Bacteria Make Up Much of the Composition of the Soil

This organism is commonly recovered from soil and water. As normal intestinal flora, it can also usually be found in sewage.
