Microalgae Photobioreactor Kit for Biology STEM Education or Home Cultivation of Fresh Water Microalgae
An experimental grade photobioreactor kit for the culturing of microalgae. 50L of fresh water microalgae culture and a bottle of nutrient liquid enough for one-year consumption are included. The kit is ready to use straight out of the box plug-and-play.
- Size: D30*100H+80*80*150H cm, < 40kg, < 0.6 m3
- Fluid volume: < 60L
- Air-revitalization power: < 9 forest tree (ref)
- Two LED Light Stripes with Timer control
- Aeration Pump
- Power supply: 100~240V AC, < 80W
- Microalgae Fluid (Euglena, valued:$2,000) 20L included
- Microalgal Nutrients 200ml (one year consumption, valued HK$500) included
- User manual and on-site commissioning service is included
- Monthly water changing:
- Drain 1/3 ~ 1/2 of algae fluid to a bucket. Add few drops of bleach into bucket to inactivate living microalgae cells before pouring the fluid into drainage
- Refill tank with direct tap water (in Hong Kong only). If there is an unusual strong smell of Chlorine in the tap water, fill it into a bucket first and then use the water after some 12 hours
- Clean the tank surfaces as needed
- Monthly nutrient feed: ~10ml
Microalgae are seen as the most promising flexible feedstock, being considered the crop of the future. They grow fast. They contain high value ingredients, such as proteins, carbohydrates, lipids, nucleic acids and others (carotenoids and polymers). Thus, they can be produced for a wide range of markets, including human and animal nutrition, cosmetics, pharmaceuticals and biofuels.
- The reactor is panel shaped 4L reactor with a single partition in indoor. The CO2 concentration of the inlet gas is 490 ppm and its flow rate is 1000 mL/min. After 24 hours, the concentration of the CO2 in the outlet gas is measured to be 146 ppm, with a consumption of 70% CO2. The reactor is able maintain over 70% CO2 consumption for the two week operation cycle.
- The reactor is a tubular reactor with a volume of 1L in indoor. The CO2 concentration of the inlet gas is 450 ppm and its flow rate is 1000 mL/min. After 24 hours, the concentration of the CO2 in the outlet gas is measured to be 90 ppm, with a CO2 consumption of over 80%. The reactor is able maintain over 80% CO2 consumption for 250 hours of operation.
- The reactor is a tubular reactor with a volume of 100L. The reactor is operated in an outdoor site. The CO2 concentration of the inlet gas is 400 ppm and its flow rate is 10L/min. After 72 hours, the concentration of the CO2 in the outlet gas is measured to be 45 ppm, with a CO2 consumption of over 80% The reactor is able maintain over 80% CO2 consumption for 18 days of operation and 40% CO2 consumption for 30 days of operation.

School Curriculum References:
A unique K-12 module that teaches the fundamentals of algae and how algae can be applied as a solution for today’s global dilemmas. This STEM kit includes everything needed for students to grow algae in their classroom: daily lesson plans; laboratory supplies, live algae and the additional consumables needed to complete the curriculum. The Algae Academy curriculum is age specific with different objectives for elementary, middle, and high school classes.
2. Algae to Energy: Optimizing Systems (web)
The concept of utilizing fast-growing, high-lipid content microalgae to produce renewable liquid transportation fuels has first garnered attention in 1960. Investments by industrial and government sectors into “green energy” alternatives to fossil fuels over the last decade greatly advanced research and technological development of sustainable, land-based biofuel crops.
However, at present, the development of novel microalgae biotechnologies is required to realize and evaluate the scaled-up, full-potential of microalgal energy systems – future technologic leaps likely conceived or discovered, years from now, by present day STEM students.
This project is designed for students in grades 9-12 in introductory to advanced biology, environmental science and engineering courses and can be modified for student in grades 7-16.

3. Synthetic Biology – Microalgae Purification System (web)
We thought about applying synthetic biology to develop a photobioreactor system consisting of microalgae (or cyanobacteria) with a few kinds of enzymes produced by genetically engineered Bacillus subtilis. The system is more efficient in improving indoor air quality than traditional air purifiers which are unable to remove CO2 and VOCs.
