Very large ciliate. Feeds on colpidium. Hay medium.
Characterized by cilia; nearly all possess two types of nuclei.

Yeast strains are ideal for genetic study because they are easy to grow and maintain, their life cycle is complete in approximately one week, and you can arrest different stages of the life cycle by growing it on different types of media.

Users can observe the sensitivity of various bacteria and fungi to an array of antibiotics with these convenient kits.

A collection of some of the strains of Escherichia coli needed to grow various coliphages (available separately).

Drosophila melanogaster, the common fruit fly, is widely used in genetic studies. They express a number of mutations such as eye, wing, and body mutations.
