Applications

Eco-sustainable approach to diverse applications

Natural plant saponins are soap-like molecules with many uses and commercial applications, ranging from disinfectants and personal care products to animal feed additives, vaccine adjuvants, pharmaceuticals, agriculture, and more.

SAPONINS

soap-like defense molecules
produced by plants

A Green Biotechnology Company

  • Developed a sustainable and cost-effective cell culture core technology platform based on natural plant physiology and defense effector mechanisms

  • Focusing on the production of phytoactives, i.e., biologically active compounds derived from specific plants or recombinant proteins

  • Major emphasis is on the production of Quillaja-derived saponin vaccine immunoadjuvants, including QS-21

  • Providing an alternative to preserve Quillaja saponaria trees under threat of rapid depletion in their natural habitat in South America, currently the only source of saponin immunoadjuvants

  • Addressing key saponin markets, such as vaccine adjuvants or organic surface disinfectants with antiviral, antifungal, and antibacterial properties
