How to cultivate Chlorella
This article provides an explanation on how to cultivate Chlorella and introduces related knowledge about the correct maintenance methods for Chlorella. It is a very useful tip worth collecting!
Chlorella belongs to the green algae group, which is a small, spherical, unicellular freshwater algae. It mainly lives in shallow water areas, with some marine species. Under natural conditions, individuals are few, but it can be mass-reproduced through artificial cultivation. It has a high content of protein, fat, and carbohydrates, which can be used as feed. Due to its excellent performance, it is widely used in aquaculture production, mainly for reducing water transparency, improving the water's buffering capacity against the external environment, providing dissolved oxygen for the water, and offering abundant feed.
Since there are no strict requirements for lighting conditions in self-cultivation, both natural and artificial lighting are acceptable. The main components of the culture medium are inorganic compounds, with the most suitable pH range between 6.5 and 7.5. Maintaining an environmental temperature of 20-30 degrees Celsius can successfully cultivate Chlorella.
Several requirements should be noted during the cultivation process:
A good culture medium is needed. The nutrient base for Chlorella is made with: sodium carbonate 0.02g/L, sodium nitrate 2.0g/L, potassium dihydrogen phosphate 0.02g/L, and urea 0.8g/L, prepared in an environment with a pH of 6.0 (for reference only). In addition to the above nutrient base formula, Chlorella is usually cultivated using SE medium, Pr medium, and BG-11 medium. Chlorella culture media can also be purchased on the market.
Choose a high-quality algae strain. Select a highly concentrated liquid Chlorella strain, preferably observed under a microscope, to ensure its survival rate.
Follow the cultivation process for Chlorella culture, and the expansion steps are as follows: Step one: Dissolve the culture medium in water by stirring; Step two: Place the algae strain at room temperature indoors for 1-2 hours to recover temperature; Step three: Pour the compound Chlorella strain into the water with the prepared culture medium and stir well; Step four: After expanding for 5-7 days, it can be used.
Cultivation conditions: 1. Water temperature: 25-30℃; 2. Lighting: Natural light or artificial light source, 12 hours of lighting and 12 hours without lighting, with the most suitable lighting intensity of 5000-10000Lux (ordinary incandescent lamps can also be used); 3. Aeration: Stirring and aeration to increase water mobility; 4. Water: Aerated and sterilized tap water, aerated for 1-2 days; 5. Expansion time: 5-7 days; 6. Usage and dosage: The expanded algae strain can be used for 50-100 acres.
