Students determine contamination levels of ground beef in different environments.

Everything you need to safetly collect and culture bacteria and fungi from your environment

Ward's® Live Escherichia coli, Lactose Negative Culture

Produces orange pigments. 

Produces streptomycin. Branching mycelium and coenocytic hyphae. 

E. coli with JM101 can be transformed with pUC8 plasmid to become resistant to Ampicillin and to metabolize lactose

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

The presence of A. viscolactis in milk is a common cause for sliminess or "ropiness".

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

Found on dental plaque, implicated in cavities. No Lancefield group shown, gamma hemolysis. 

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

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

This pathogenic organism is sometimes isolated from hay and grass.

Isolated from the alimentary tract of cows. Lancefield group D, gamma hemolysis. May be pathogenic in humans. 

A collection of some of the strains of Escherichia coli needed to grow various coliphages (available separately).

Capsules produced in milk. Psychrophilic (prefers low temperatures), produces yellow pigments.
