Spirulina live culture refers to the actively growing, living form of the microalgae Spirulina (Arthrospira) maintained in a controlled liquid medium. Unlike dried powder or processed forms, the live culture contains viable, reproducing cells that are continuously photosynthesizing and multiplying under suitable light, temperature, and nutrient conditions.
Spirulina is a blue-green microalgae known for its high nutritional value and when kept as a live culture, it remains in its most natural and active biological state. It is typically cultivated in open ponds or closed photobioreactors where conditions such as pH (alkaline), salinity, and light intensity are carefully managed.
KEY FEATURES
- Active growth state with continuous cell division
- Deep green-blue suspension due to high chlorophyll and phycocyanin content
- Requires light (natural or artificial) for photosynthesis
- Thrives in alkaline water (pH ~9–11)
- Sensitive to contamination, requiring controlled cultivation conditions
KEY BENEFITS
High Nutritional Potency
- Rich in protein, vitamins (B-complex), minerals (iron, magnesium) and antioxidants like phycocyanin.
Fresh and active biomass
- Cells are alive and metabolically active, meaning higher biological quality compared to dried forms.
Fast growth rate
- Multiplies quickly under proper light and alkaline conditions, making it efficient for production.
Eco-friendly production
- Requires low land use and can grow using simple mineral-rich water systems.
High adaptability in applications
- Suitable for aquaculture feed, bioproduct development, and research use.
TARGET APPLICATIONS
Aquaculture feed production
- Used to enrich live feed systems (rotifers, artemia, zooplankton) and improve fish/shrimp larval nutrition.
Commercial Spirulina farming
- Serves as a starter inoculum for large-scale production of Spirulina biomass in ponds or photobioreactors.
Research & Biotechnology
- Used in studies involving microalgae growth, bioactive compounds, and photosynthetic efficiency.
Environmental Applications
- Used in wastewater treatment research due to nutrient uptake capability and oxygen production.
DIRECTIONS OF USE
- Add Spirulina live culture directly into the live feed tank until the water becomes light green.
- Feed 1–3 times daily depending on organism density and water clarity.
- Maintain gentle aeration to keep the algae suspended evenly.
