Protists - Living Material

This species of freshwater algae is commonly used for research on photosynthesis.

Freshwater. Unicellular; desmid. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

Freshwater; large placoderm desmid; well-shaped semi-cells.

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. Homothallic strain. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

Freshwater. Colonial; colonies elliptical, made up of 16–32 cells. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

Freshwater. Colonial; polygonal cells. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

Volvox globator is a species of colonial green algae that forms spherical colonies of cells.

Pink to bright rose color.
Characterized by cilia; nearly all possess two types of nuclei.

Paramecium bursaria is a ciliate that contains mutualistic algae called Zoochlorella. The algae lives in the cytoplasma of the Paramecium and provides it with food. Paramecium bursaria grows in Dilute Alfalfa Medium (Hay Medium) or Soil Water Medium. Requires light for growth.

Paramecium multimicronucleatumis one of the largest species of Paramecium. This ciliate contains a single macronucleus and four or more micronuclei. Grows in Dilute Alfalfa medium (Hay Medium).

A very large Protozoa that graphically demonstrates the basic animal cell.

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.)

Demonstrates isogamous reproduction where gametes are similar in appearance and behavior. Make lectures and labs on protist reproduction clearer with our specially selected cultures that illustrate various reproductive phenomona.

Marine. Filamentous. Branched thallus, zoospores. Erdschreiber’s medium.

Kelp and seaweed; with a distinct set of photosynthetic pigments.

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

Characterized by flagella; lacks plastids.

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

Cellular slime mold. Demonstrates amoeboid state, pseudoplasmodial state, and fruiting body, or sorocarp. Found in woodland soil in decomposing vegetation where bacteria are abundant. Incubation temperature 25°C. Plate cultures grown with Enterobacteria as food source; freeze-dried cultures include food source.

Characterized by an amoeboid stage (lacking cell walls) and a fungus-like reproductive structure.
