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. 

Produces orange pigments. 

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.

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

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.

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

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

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.

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.
