Produce a Variety of Organisms Simply by Adding Water

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

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

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.

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

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

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

Characterized by green plastids and cell walls composed of cellulose.

Use this cone-shaped fine-mesh nylon net to let water pass while you filter out plankton.

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.

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.

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 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).
