Penicillium notatum is a deuteromycete that produces penicillin. It is available in normal and high-yield strains.

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

Cellular slime mold. Demonstrates amoeboid state, pseudoplasmodial state, and fruiting body, or sorocarp. Found in woodland soil in decomposing vegetation where bacteria are abundant. Incubation temperature 25°C. Plate cultures grown with Enterobacteria as food source; freeze-dried cultures include food source.

Characterized by an amoeboid stage (lacking cell walls) and a fungus-like reproductive structure.

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

When hatched, the small, gray larvae are the traditional source for high-quality silk.

This harmless insect parasitizes the Sarcophaga (flesh fly) pupae. Females usually lay 30–50 eggs in the pupae, which provide food for the Nasonia larvae when they hatch.

This large predatory frog will eat any other organism smaller than itself, including smaller bullfrogs; keep similar-sized frogs together to avoid cannibalism.

Includes one 30 student unit of Volvox and a Form and Structure copymaster.

Live Cultures are supplied with media in 16 x 125 mm tubes, 2 oz. jars, or 8 oz. jars. Fast delivery is available directly from our laboratory. Please specify a delivery date.

Each culture shipment is prepared in our laboratories and includes the "Working with Algae & Cyanobacteria" manual which contains detailed instructions for subculturing and use.

Canadian Customers:
CFIA and PHAC regulations require customers to submit a completed inspection checklist and signed statement of facilities compliance before receiving certain cultures. A customer service representative will contact you if documentation is required.

Our cultures undergo strict biochemical screening and are unconditionally guaranteed for species and purity. Each culture is labeled with scientific name, media on which it was cultivated and optimum growth temperature. Although our cultures are considered non-pathogenic, standard bacteriological laboratory procedures should be used at all times. Cultures are available either live for immediate use or freeze-dried for convenient storage until needed. (Please note: We are not responsible for any infection resulting from the use of our cultures.)

The set Includes cultures of wild, white, brown, dumpy, vestigial, vestigial brown and sepia.

We fully guarantee the purity and viability of our Drosophila melanogaster cultures. A large, vigorous culture is shipped in a shatterproof plastic vial. To ship Drosophila cultures with living larvae we require 10 days' notice prior to use date. During very cold weather, adult flies may die but eggs and larvae usually survive. Allow cultures to come to room temperature before checking under low magnification for eggs and live larvae. Complete instructions are always included.

Study the lifecycle of the brown house cricket (Acheta domesticus) with this complete culture kit ideal for behavioral studies, food for insectivorous animals, or both.

These African clawed frogs are entirely aquatic and thrive in an ordinary freshwater aquarium. They are often used in developmental studies and genetic experiments.
