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.

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

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

Normal flora of respiratory tract. Beta-lactamase positive. Also known by the name Branhamella catarrhalis

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

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

Nitrogen fixation, produces nodules on legume roots. Bacteroids from nodules can be X, Y, and club shapes.

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