Chlorella sorokiniana

Chlorella sorokiniana is a species of unicellular green microalgae belonging to the family Chlorellaceae. It is recognized globally for its extraordinary photosynthetic efficiency and rapid growth rate, which allows it to produce high amounts of biomass rich in proteins, lipids, and various bioactive compounds essential for agricultural use.

The species has a broad distribution, naturally occurring in diverse freshwater ecosystems and soils across the globe. Its resilience to various environmental conditions, particularly high temperatures, has allowed it to thrive in diverse habitats, making it a highly reliable and versatile candidate for industrial-scale cultivation in varied climates.

Botanically, the organism is defined by its spherical morphology and a complex cell wall structure. It reproduces through the formation of autospores within the parent cell. A significant biological characteristic of Chlorella sorokiniana is its superior heat tolerance compared to other species in the Chlorella genus, allowing it to remain productive in conditions reaching 40°C.

Successful cultivation requires specific agronomic conditions, including controlled light intensity, supply of nutrients such as nitrogen, phosphorus, and carbon dioxide, and precise temperature management. In agricultural settings, it is primarily used as a liquid biofertilizer to enhance soil fertility, a high-protein supplement in animal feed, and a key agent for remediating nitrogenous waste.

Commercial production faces challenges related to biological contamination, including viral outbreaks, predatory zooplankton, or invasive fungi that can outcompete the desired strain. To mitigate these risks, farm managers utilize rigorous sterilization protocols for growth media and automated sensors to maintain optimal pH and nutrient concentrations, ensuring the health of the algal culture.
