Please state the expected use date and allow sufficient time for proper handling. Helpful Ordering Hint: To ensure you order enough living materials for the number of students in your class, order 1 culture for up to 30 students, 2 cultures for 31 to 60 students, 3 cultures for 61 to 90 students, etc. Organism Description Medium Temp Catalog No. Each Blepharisma Two interesting features can be studied in this rose-colored ciliate: the effect of light on pigmentation and the normal occurrence of giants Wheat Seed + Carolina® Springwater 22° C 131430 $8.70 Bursaria truncatella One of the largest ciliates known; feed ciliates such as paramecium or Spirostomum and digestion can be studied Carolina® Springwater + Ciliates (e.g., Paramecium or Spirostomum) 22° C 131434 $8.70 Colpidium striatum A small ciliate, easily cultured in large numbers in simple media; one of the chief food organisms for many other protozoa Protozoan Pellet + Wheat Seed + Carolina® Springwater 22° C 131452 $8.60 Didinium One of the better-known examples of a predator-prey relationship, as it feeds exclusively on paramecia Paramecium multimicronucleatum 22° C 131460 $8.70 Dileptus sp. A striking ciliate that uses toxicysts on its long, flexible proboscis to capture prey Carolina® Springwater + Wheat Seed 22° C 131466 $8.70 Euplotes An interesting ciliated protozoan with a bandlike macronucleus and regionally grouped cirri Carolina® Springwater + Wheat Seed 22° C 131480 $8.70 Paramecium sp. P. multimicronucleatum is generally supplied; the organism is characterized by a single macronucleus and 3 or 4 micronuclei Carolina® Springwater + Wheat Seed (Protozoan Pellets can be added as extra nutrients) 22° C 131540 $8.70 Paramecium multimicronucleatum, Conjugating Two separate cultures, each containing a mating type for conjugation Protozoan Pellets 22° C 131558 $18.15 Paramecium aurelia One of the smaller species with a macronucleus and 2 small micronuclei Carolina® Springwater + Wheat Seed (Protozoan Pellets can be added as extra nutrients) 22° C 131546 $8.70 Paramecium bursaria An excellent example of symbiosis; green in color because of zoochlorella in its cytoplasm Protozoan Pellets 22° C 131548 $8.70 Paramecium caudatum Has a massive macronucleus and a compact micronucleus Carolina® Springwater + Wheat Seed (Protozoan Pellets can be added as extra nutrients) 22° C 131554 $8.70 Paramecium tetraurelia Used extensively in research for genetic studies; large in size (as large as 120 µm) with a macronucleus and micronucleus Protozoan Pellets and Carolina® Springwater 22° C 131560 $8.70 Spirostomum Has highly developed lengthwise myonemea Carolina® Springwater + Wheat Seed 22° C 131590 $8.70 Stentor coeruleus The blue stentor with its macronucleus Chilomonas + Wheat Seed 22° C 131598 $8.70 Tetrahymena pyriformis Bacteria-free tube culture Tetrahymena Medium 22° C 131620 $10.85 Vorticella A stalked, bell-shaped, peritrichous ciliate Field collected (may contain other organisms), not recommended for culturing 22° C 131660 $10.15 Shooting Trichocysts! Did you know you could induce paramecia (item #131540) to discharge their trichocysts? Add a small drop of vinegar to a drop of liquid medium containing active cells on a slide. Trichocysts are capsulelike organelles that paramecia extrude in response to certain environmental stimuli (e.g., chemical, mechanical, or electrical). Although their exact function is unknown, trichocysts may act as anchoring devices or defense mechanisms. Customer Review “Specimen arrived on time and was of great quality. They were very lively and suited my purposes perfectly.” High School Biology Teacher Blepharisma An excellent choice for use by amateur microscopists! Moves more slowly than paramecia and the rosy color makes it easy to observe. Coloration is dependent on exposure to light during the culture process. 131430 Per culture $8.70 Stentor coeruleus Vivid blue pigmentation and sessile nature make this protist hard to miss. Students will want to observe its adoral zone membranellae, a ciliated organ that creates a vortex to pull food particles into the cytostome. 131598 Per culture $8.70 The Competitive Paramecia! For competition studies between species of paramecia, we suggest using Paramecium multimicronucleatum (item #131540) and P. aurelia (item #131546). Both are hardy species, easily cultured on wheat seed medium. The 2 paramecia are also easily distinguished because of the drastic difference in their size.
