Formalin preserved sheep brains with dura mater intact.

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

This organism is commonly isolated from soil or water, and produces a pink or rose colored pigment.

Freshwater. Unicellular. Soil-water medium. Characterized by two flagella (one inside a groove at right angles to the other); most also have tests made of cellulose and are encrusted with silica.

This species of Rhodospirillum is commonly isolated from stagnant water and mud. It is especially interesting because it produces a red pigment and is also capable of photosynthesis.

Freshwater. Colonial. Sheet of many cells one cell thick. Soil-water medium.

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 found in soil and water, and is also associated with spoiled food. It produces a diffusible fluorescent pigment.

This organism is commonly recovered from soil and water. As normal intestinal flora, it can also usually be found in sewage.

From soil and water rich in minerals. Organism of putrefaction.

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

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

Found in fresh water. Chromogenesis; blue to purple pigments produced. Motile. Rods. Gram negative reaction. Aerobic. Incubation temperature 30°C. Blood agar growth medium. Note: Pathogen.

Packaged in a 16×125 mm tubes. Call our Customer Service for availability of demo plates and other special orders.

This organism can be isolated from many human urinary tract infections, as well as polluted water and sewage. It is commonly identified by its distinctive grape-like smell (trimethylamine) or because it can turn the agar light green due to production of a blue pigment (pyocyanin).

Freshwater. Filamentous; H-shaped cell walls. Soil-water medium.

Characterized by green plastids and cell walls composed of cellulose.

Freshwater. Unicellular; heart-shaped cell. Soil-water medium.

Characterized by a lack of rigid cellulosic walls, instead these organisms have pellicles made of protein. They store paramylon instead of starch.
