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

Ward's® Live Escherichia coli, Lactose Negative Culture

Produces streptomycin. Branching mycelium and coenocytic hyphae. 

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

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

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.

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

Freshwater. Filamentous. True branching, dimorphic structure. Basic culture solution.

Shipped in a form that provides the best quality specimen. Most are supplied in 16 x 125 mm tubes, 2 oz. jars, or 8 oz. jars..

This organism is commonly isolated from sewage, water, soil and dairy products, as it is a normal part of intestinal flora.

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

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

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

This yellow, shiny organism is known to cause wound infections and more famously, toxic shock syndrome.

Red-pigmented halophile from evaporating salt ponds; requires 25% salt medium, lyses easily in plain water, releasing DNA.
