"VWR"

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

Organisms with Characteristics of Two Kingdoms

Basidiomycete. Inky-capped mushroom. Jar culture. Incubation temperature 30°C. YM/rabbit dung agar growth medium.

Water mold and fish parasite. Demonstrates sporangia and oospores. Grows on wheat seed, cucumber seed, or hemp seed in water environment. Reproduces sexually and asexually. Incubation temperature 25°C.

Cell walls made of cellulose; feeds by extending hyphae into host's tissue.
