"Ward's Phenomena"

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.

Axenic culture. Food organism. Tetrahymena medium.

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

Freshwater; unbranched cells with parietal chloroplasts; produces zoospores.

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

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. Colonial; polygonal cells. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

One jar containing a mixture of 6 different genera of algae. Each algae is cultured individually in Ward's laboratories, and mixed together immediately prior to shipment to ensure an adequate supply of each organism.

Marine. Unicellular; brackish, centric cells. Marine medium.

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

Extremely small euglenoid. Usually doesn’t rotate when swimming. Scavenger. Hay medium.

Characterized by flagella; lacks plastids.

Marine, Macroalga, Multicellular; membranous thallus. Collected. Characterized by green plastids and cell walls composed of cellulose.

Usually found in freshwater and mosses, this organism has a hard umbrella shaped shell or "test", out of which finger-like pseudopodia project.

Examples of Organisms That Grow in Colonies

Lives in intestine of host — mealworms — as symbiotic organism. Culture of mealworms provided.

One Culture from Each of the Four Major Types

Specially Prepared “Real-Life” Combinations
The world is teeming with a wide variety of micro life, making studying samples of pond water complicated especially for the beginning student. To lessen the confusion, Ward's has prepared different culture mixes that reflect protist combinations that occur in the real world, yet eliminates the hundreds of other life-forms found in a collected sample.

Spirogyra is a genus of filamentous green algae with chloroplasts arranged in a helical (spiral) pattern.
