"AMERICAN TYPE CULTURE COLL."

This organism can be isolated from soil, wounds, and intestinal tracts of humans. It digests protein and is known for its strong, distinctive odor.

Azotobacter vinelandii is an aerobic organism normally found in soil, and is commonly known for its ability to fix nitrogen, converting it to ammonia.

Colorless, most widely dispersed of the Serratia species. 

Red-pigmented halophile from evaporating salt ponds; requires 25% salt medium, lyses easily in plain water, releasing DNA.

Use Sordaria fimicola to allow students to visualize the results of crossing over during cell division.

This organism is an aerobic organism that is commonly found as part of normal human intestinal flora. It is pathogenic.

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

Zygomycete. Common black bread mold. Lab contaminant. Mating strain, cross with Rhizopus stolonifer (nigricans) (-) to produce zygospores. Incubation temperature 25°C. Potato dextrose agar growth medium.

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

Both of these strains of Serratia marcescens are colorless mutants when plated alone, but when grown together, they produce a red pigment.

Two o strains of Escherichia coli; one exhibiting Ampicillin resistance, and one sensitive, but competent and ready to receive the plasmid that confers resistance.
