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

Ward's® Live Escherichia coli, Lactose Negative Culture

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

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

Produces streptomycin. Branching mycelium and coenocytic hyphae. 

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

Found in seawater and marine animals. Young cultures luminescent.

Frequent human isolate. Causes gastroenteritis.

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

From sewage and human intestine. Causes dysentery. 

This organism is normal flora of human skin.

This organism is normally isolated from soil and is a non-pathogenic strain of the mycobacterium genus.

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

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