Cultivated in San Diego labs, this versatile culture supports diverse aquatic habitats and has a proven track record, including three space missions. Perfect for educators seeking an affordable, easy-to-use tool to engage students in cutting-edge aquatic science. ## Description So much fun to grow. Easy to harvest (see Algae Research Supply's Spirulina Farming Kit). Great model organism to teach photosynthesis and aquaculture. ## Features - ALGAE CULTURE: In our labs in San Diego we grow algae and zooplankton cultures for most habitats on our planet (and perhaps Mars!) We carry freshwater, brackish, marine, and extremophile cultures of algae. They grow to exhibit colorful pigments of red (phycoerythrin), orange (carotenoids), brown (fucoxanthin), blue green (phycocyanin), and our favorite->green (chlorophyll). Our algae strains have been selected because they are grown well in bottles and flasks. - SCIENCE PROJECT: Teachers, parents, and students - grow algae easily and get great results for inquiry-based projects. Because algae grow FAST experiments take a fraction of the time as land-plants (and algae is cooler!) Great experiments: toxicology, light quality, environmental changes, algae blooms. Blog posts detail science-fair winners and other projects. Students have sent our algae into SPACE THREE TIMES (would have been four, but the rocket exploded.. we still love you Space X.) - WHO WE ARE: Algae Research Supply is a small group of teachers and scientists with a mission of educating the next generations on aquatic science. Over 50% of the planet's oxygen comes from algae, however we are not emphasizing algae's importance in school- our mission is to make it EASY, AFFORDABLE, and REPEATABLE to teach algae in classrooms. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Algae Research Supply | | Manufacturer | Algae Research Supply | | Model number | AC | | Colour | Spirulina (Arthrospira platensis) | | Number of Memory Sticks | 1 | | Item model number | AC | ## Images ![Algae Research Supply Algae Culture Spirulina, Perfect for School Science Fairs/Projects, Experiments & Classrooms (50mL) - Image 1](https://m.media-amazon.com/images/I/71Ij+kSiNUL.jpg) ![Algae Research Supply Algae Culture Spirulina, Perfect for School Science Fairs/Projects, Experiments & Classrooms (50mL) - Image 2](https://m.media-amazon.com/images/I/91CEPGkzlqL.jpg) ## Available Options This product comes in different **Color, Size, Number Of Items** options. ## Questions & Answers **Q: Hi laura, my question is if this culture is safe to eat (fda?) after harvesting. or is this also for research purpose?** A: Hi Tim,Spirulina is a safe organism to eat. It is how it is raised and prepared that can become problematic. If it is grown in water with a pH around 10, the probability of problems is lessened. Also cleaning the algae after harvest is advised, and drying helps to kill pathogens. Finally, I must state (as my wife is a lawyer), eating anything you grow at home, be it beans, corn, or spirulina; how you grow it effects the safety of the product. Therefore, we offer no guarantee, warrantee, or prediction of safety if you choose to consume this product or feed it to animals. That said, I have not had any one tell me that they have had any problems. **Q: Spirulina platensis, Spirulina maxima, Spirulina fusiformis? What is it?** A: To the best of my knowledge they are all the same species. But technically, S. Platenais. **Q: Without adding nutrients, how much can this algae grow in 5 days?** A: It will contain enough nutrients in the biomass itself (luxury uptake) to likely double. The media it ships with will have enough to more than double as well. **Q: how much solution will this make?** A: You question is a bit vague I think, but I will answer to the best I can.Infinite if done properly, and continue to build your nutrient solution to feed the algae culture as you harvest.I was able to fill 5 gallons and used less than half of the liter, and it was enough to grow very well. So I will be harvesting and adding more nutrient solution to keep it going. I imagine it's at least enough to start 3x five-gallon tanks, but if you plan on growing it out, you will gain an infinite supply if you take care of it. ## Frequently Bought Together - Algae Research Supply Algae Culture Spirulina, Perfect for School Science Fairs/Projects, Experiments & Classrooms (50mL) - Algae Research Supply Algae Research Supply Salts Spirulina Alkali Media, Makes 5 Gallons, Perfect for School Science Fairs/Projects, Experiments & Classrooms - Algae Research Supply Nutrient Media F/2- Grows 50L of Algae Culture in Freshwater & Seawater --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/736792947-algae-research-supply-algae-culture-spirulina-perfect-for-school-science](https://www.desertcart.pt/products/736792947-algae-research-supply-algae-culture-spirulina-perfect-for-school-science) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-07*
