"3B torso model"

Predatory. Feeds on Paramecium caudatum. Hay medium.

Characterized by cilia; nearly all possess two types of nuclei.

This organism is easily recognized by its trumpet-shape, and can commonly be found in freshwater ponds and streams. It reproduces by budding.

Ward's® Live Diatom cultures

Freshwater; unbranched filaments with cylindrical- to slightly barrel-shaped cells; shows the characteristic H-pieces upon fragmentation of the filament.

Live Cultures are supplied with media in 16 x 125 mm tubes, 2 oz. jars, or 8 oz. jars. Fast delivery is available directly from our laboratory. Please specify a delivery date.

Each culture shipment is prepared in our laboratories and includes the "Working with Algae & Cyanobacteria" manual which contains detailed instructions for subculturing and use.

Canadian Customers:
CFIA and PHAC regulations require customers to submit a completed inspection checklist and signed statement of facilities compliance before receiving certain cultures. A customer service representative will contact you if documentation is required.

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

Characterized by green plastids and cell walls composed of cellulose.

Marine. Filamentous; unbranched thallus. Erdschreiber’s medium.

Characterized by reddish plastids (rhodoplasts).

Two flagella; no chloroplasts. Food organism. Hay medium.

Characterized by flagella; lacks plastids.

Test cylindrical, covered with sand granules. Soil-water medium.

Characterized by pseudopods; with or without a shell (test).

Freshwater. Colonial; net-like structure with multinucleated cells. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

Freshwater. Unicellular; triangular desmid. Basic culture solution. 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.

Marine. Unicellular; contains same pigments as other Golden Algae but contains haptonema, unique to Haptophyceae. Coccoid, from coccoliths. Marine medium. Characterized by golden yellow plastids.

Axenic culture. Food organism. Tetrahymena medium.

Characterized by cilia; nearly all possess two types of nuclei.

The body of this ciliate is transparent, making the large cilia clearly visible.

Our cultures undergo strict biochemical screening and are unconditionally guaranteed for species and purity. Each culture is labeled with scientific name, media on which it was cultivated and optimum growth temperature. Although our cultures are considered non-pathogenic, standard bacteriological laboratory procedures should be used at all times. Cultures are available either live for immediate use or freeze-dried for convenient storage until needed. (Please note: We are not responsible for any infection resulting from the use of our cultures.)

Freshwater, Unicellular; pennate, with bilateral symmetry. Diatom or basic medium.

Characterized by shells (tests) made of silica, in two parts.

Marine. Filamentous; freely branched. Erdschreiber’s medium.

Characterized by green plastids and cell walls composed of cellulose.
