"AMERICAN TYPE CULTURE COLL."

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

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.

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

From soil and water rich in minerals. Organism of putrefaction.

Dramatic Results Mimic Effects of Sun on Living Tissue

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

All microbial cultures undergo an extensive quality control program prior to releasing for sale, so they are guaranteed for purity as well as for species.

A Common Intestinal Flora Isolate, Demonstrates Alpha Hemolysis on Blood 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.

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

Colorless, most widely dispersed of the Serratia species. 

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.

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