Macro partitioning
The protein content of microalgae varies significantly (6-71% of dry matter) and is heavily influenced by environmental factors such as light intensity, temperature, CO2 concentration, and nutrient availability.
When choosing microalgal products, be aware that protein content can vary widely depending on how the algae were grown. Look for products that specify their protein content, as this can range from 6% to over 70% of dry weight depending on cultivation conditions.
GoodQualifiesHIGH confidence
Protein contents can be vastly different among microalgal species and strains... is substantially affected by the environments in which they are grown... typically 40–60% of dry matter... ranges from 6 to 63%
Why this rating
The paper reviews multiple studies showing significant variability in protein content based on environmental factors.
