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

Oscillatoria is a genus of filamentous green algae that moves by sliding filaments back and forth against each other.

This organism is a common environmental isolate, and can be found in soil as well as in industrial settings.

Colorless, most widely dispersed of the Serratia species. 

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 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.
