General Description of the Research Project

Discovering and mass-culturing high-value microalgae using new technologies
Microalgae are capable of producing powerful antioxidants such as astaxanthin. Both aesthetically and functionally beneficial, they are truly worthy of the title “aquatic jewels.” Malaysia is one of the most biologically diverse nations, and habitat to a vast population of microalgae species. Our goal is to establish advanced microalgae mass-culture reactors suited to tropical ecoclimate conditions using targeted high-value microalgae coupled with innovative growth-promoting substances from Malaysia.

Contributing to the development of environmentally-friendly aquaculture industries through innovative microalgae mass-culture technologies
The rapid growth of aquaculture industry has led to the discharge of large volumes of sludge and sewage into the natural environment causing degradation to ecosystems. The proactive recovery of rich nutrients from the sludge and sewage can be utilized for the mass-culturing of high-value microalgae species, empowering a new recycling system that provides economic incentive while simultaneously preserving the natural ecosystem.
