Nannochloropsis live culture refers to the controlled growth of this microalgae under specific conditions such as light, temperature, salinity, nutrients, and aeration. It is typically cultivated in either indoor photobioreactors or outdoor ponds to produce high density algal biomass. Nannochloropsis is a genus of microalgae widely used in aquaculture, biotechnology and bio product industries. It is a small, single celled marine phytoplankton known for its high nutritional value especially its rich content of lipids, proteins and essential fatty acids such as EPA (eicosapentaenoic acid).
KEY FEATURES
- Fast growth rate under optimal conditions
- High lipid content, especially omega-3 fatty acids (EPA)
- Rich in protein and pigments useful for nutrition and aquaculture
- Easy to maintain in controlled systems
- Highly resistant to contamination compared to other microalgae
