Bacterial Classification and Morphology Set
Bacterial morphology, the shape of the individual cells, is the primary characteristic
used to classify this enormously complex group. Set includes individual tube
cultures of Bacillus subtilis (rods/bacilli), Micrococcus luteus (spheres/cocci) and
Rhodospirillum rubrum (spirals/spirilli).
Catalog No. Description Price/Set
LM1017 Bacterial Classification and Morphology Set $38.38
High School
Bacterial Collection
Convenient collection of six different bacteria cultures representing different chemical
and morphological groups. Cocci, bacilli, and spirilli representatives can all be
grown on common nutrient agar. One culture each of:
• Bacillus megaterium • Rhodospirillum rubrum
• Micrococcus luteus • Serratia marcescens
• Pseudomonas fluorescens • Escherichia coli
Catalog No. Description Price/Set
LM1236 High School Bacterial Collection $86.86
Bacterial Pigmentation Set
Demonstrate the diversity of pigments produced by bacteria with this set. Pigment
formation (chromogenesis) can, in most cases, be easily influenced by the manipulation
of incubation temperatures. Set includes individual tube-cultures of Micrococcus
roseus (pink), Serratia marcescens (red), and Micrococcus luteus (yellow).
Catalog No. Description Price/Set
LM1018 Bacterial Pigmentation Set $49.88
Fungal Cultures
Maintenance requirements for fungal cultures are similar to those for bacterial
cultures. Fungal culture media are typically more acidic and higher in carbohydrates
than bacterial media. Fungal cultures take five days to develop.
Catalog No. Description Incubation Temp. and Medium Price/Each
LM1019 Aspergillus niger. Ascomycete. Black mold found on plants. Citric acid producer. 25 °C Potato Dextrose Agar $12.79
LM1022 Rhizopus stolonifer (nigricans). Minus Zygomycete. Black bread mold. Used with
plus strain for zygospore demonstration.
25 °C Potato Dextrose Agar 12.79
LM1023 Saccharomyces cerevisiae. Ascomycete. Baker’s and brewer’s yeast. 25–30 °C Potato Dextrose Agar 12.79
LM1150 Sordaria fimicola. Wild type. Ascomycete. Produces brown ascospores. 30 °C Cornmeal-Glucose-Yeast Agar 12.90
LM1219 Sordaria fimicola. Tan Mutant. Ascomycete. Produces tan ascospores. 30 °C Cornmeal-Glucose-Yeast Agar 12.90
LM1259 Sordaria fimicola. Wild/Tan Combination Plate. 30 °C Cornmeal-Glucose-Yeast Agar 29.56

Slime Molds
A group notable for its unwillingness to be neatly classified. Grouped with the Protista
because their vegetative state is a mobile amoeboid mass, and with the fungi due
to their production of fungus-like fruiting bodies. Like the fungi they also produce
spores with cell walls. Slime-molds live primarily in moist habitats on decaying plant
matter, consuming bacteria and other microorganisms. Physarum polycephalum
develops bright orange-yellow plasmodia and is readily cultured so that all stages
can be studied and observed. Slime mold cultures take five days to develop.
Catalog No. Description Price/Each
LM1025 Physarum polycephalum—plasmodium. The active stage of the life cycle,
popular for observation of its amoeboid motion and cytoplasmic streaming.
Supplied as plate culture on oatmeal agar.

$16.18
LM1026 Physarum polycephalum—sclerotia. The dormant stage of the life cycle,
can retain its viability up to a year. Supplied as a vial of dried sclerotia
on 5–7 filter paper strips. Easily regenerated to form plasmodia.
15.80
LM1027 Physarum Study Set. Includes both plasmodium and sclerotia as described
above, plus: one plate of oatmeal agar (for regenerating sclerotia), one
filter paper plate (for inducing sclerotial stage), one small jar of oats for
culturing, and complete instructions.
