Protoga Bio

Protoga Biotech serves a diverse clientele across the food, healthcare, and cosmetics industries. Its business revolves around a proprietary Synbio platform that uses precision fermentation in a closed-system to cultivate microalgae from inexpensive carbon sources. This method allows for the production of high-value ingredients. A key aspect of their sustainable approach is the repurposing of liquid by-products from the fermentation process into items like plant fertilizer. The company has successfully raised nearly RMB 100 million through three financing rounds, including a Series A round of $13.9M in August 2023, to scale its operations.

The firm's product portfolio is extensive, including DHA microalgae oil, microalgae protein, astaxanthin, and chlorella polysaccharides. A notable development is their microalgae-based milk alternative, produced from a powder derived from microalgae, which is rich in protein and lutein while being free from lactose and cholesterol. The company adjusts the cultivation process to manage the stability, texture, and taste of its products. To ensure quality and safety, Protoga Biotech holds several international certifications, including ISO 9001, ISO 22000, HACCP, Halal, and Kosher.
