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.

Penicillium notatum is a deuteromycete that produces penicillin. It is available in normal and high-yield strains.

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

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

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

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

A Common Intestinal Flora Isolate, Demonstrates Alpha Hemolysis on Blood Agar Growth Medium

Lancefield group A, beta hemolysis. Sensitive to bacitracin. Causes strep throat, rheumatic fever, and scarlet fever.

This organism is often times isolated from food; in large amounts it can cause food poisoning

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. 

Kocuria rhizophila is also commonly known by the name Micrococcus luteus. This organism is commonly isolated from soil, and is frequently used to test antimicrobial efficacy in the food industry.

Isolated from human saliva, sputum, and intestine. No Lancefield group shown, alpha hemolysis.

This organism is a common inhabitant of intestinal flora, and can be a major cause of urinary tract infection.

This organism is normal flora of human intestine and may be pathogenic in humans. This organism will grow in Sodium chloride solution.

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