Bacteria - Living Material

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 is commonly isolated from human nasopharyngeal mucosa

Isolated from milk and cheese products. Can be used to ferment milk. 

Isolated from human nasopharynx, saliva, and sputum. Spontaneously agglutinates in saline.

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

This organism is commonly isolated in soil and produces antibiotics such as bacitracin, subtilisin, and mycobacillin.

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 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 human nasopharynx. Presumably not related to N. sicca; some relation to N. gonorrhoeae. Often agglutinates in saline. 

Grows on dead tissues. Novobiocin resistant (S. epidermidis and S. aureus novobiocin sensitive). 

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

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

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

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