"The Mystery of Lyle and Louise"

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.

Study the Rotifera under your microscope to discover the variety of structures among them. Subculture them in Alfalfa or Hay medium to increase your supply. Species may vary based on availability.

This organism is often times isolated from food; in large amounts it can cause food poisoning

Isolated from soil. Forms red pigment (best on high carbohydrate medium) and has oval eccentric spores. 

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.

This harmless insect parasitizes the Sarcophaga (flesh fly) pupae. Females usually lay 30–50 eggs in the pupae, which provide food for the Nasonia larvae when they hatch.

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

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).

Isolated from human nasopharynx. Presumably not related to N. sicca; some relation to N. gonorrhoeae. Often agglutinates in saline. 

Grows on dead tissues. Novobiocin resistant (S. epidermidis and S. aureus novobiocin sensitive).
