"Avantor"

Hemolysis, the rupture of red blood cells, is induced by certain species of streptococcal bacteria that produce extracellular hemolysin.  Observe this phenomenon with this set of 3 non-pathogenic species

Two strains of Escherichia coli (donor and host) with complementary sensitivities to Ampicillin and Streptomycin. Watch them trade traits via conjugation.

Isolated from human urinary tract and wound infections, this organism is identifiable by its characteristic putrefactive odor. 

Three Morphology Types in One Tube

Supplied as tube cultures. Comes with culture and handling instructions, as well as the manual Working with Fungi.

Eight strains: a1 (HAO), α1 (HBO), a2 (HAR), α2 (HBR), a3 (HAT), α3 (HBT), a4 (HART), α4 (HBRT).

Fascinate students with some of the simplest light-producing organisms

Deuteromycete. Biological control organism. Traps nematodes. Incubation temperature 25°C. Cornmeal agar growth medium.

Deuteromycete. Causes thrush, candidiasis. Multiplies by budding. Forms germ-tubes in serum cultures. Incubation temperature 37°C. Potato dextrose agar growth medium. Note: Pathogen.

Ascomycete. Host for rDNA. Incubation temperature 30°C. Sabouraud dextrose/YM agar growth medium.

Zygomycete. Dung Mold. Mating strain; cross with Mucor heimalis (-) for zygospore formation. Incubation temperature 25°C. Potato dextrose agar growth medium

Freshwater. Unicellular; large cells, with four flagella. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

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.

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

Paramecium aurelia is the smallest species of Paramecium we offer. Paramecium aurelia is characterized by cilia, which it uses for locomotion and feeing. Contains a macronucleus and two micronuclei. Grows in Dilute Alfalfa Medium (Hay Medium).

Examine the morphological characteristics of typical soil nematodes with the specimens in our well-populated culture.

Hypsibius sp. The water bear is a complex animal representing the unusual phylum of Tardigrades, which contains about 400 marine, terrestrial, and freshwater species.
