Continuous Operation System for Microalgae Production
Optimized for Sustainable Tropical Aquaculture (COSMOS)

The rapid growth of aquaculture industry has led to the discharge of large valumes of sludge and wastewater into the natural environment causing degradation of ecosystems. The proactive recovery of rich nutrients from the aquaculture sludge 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.

High-value microalgae
Growth promoters

Discover native,
high-value microalgae.

Native microalgal species collected from various coastal and inland water bodies will be evaluated and selected based on their productivity of biomass and valuable substances. The selected microalgal species will be cultivated to see what emvironmental conditions are suitable for the highest production of high-value compounds.

Explore natural growth promoters for
enhancing microalgae productivity.

To maximize the production of high-value microalgae, artificial culture medium alone are not adequate, but nature-based nutirents are also essential. We will explore growth-promoting substances from natural environments such as tropical forests, lakes and rivers. The exploration of growth-promoting substances may lead to a breakthrough of microalgae cultivation.

Nutients

Pioneer a photobioreactor for optimum microalgae
mass-culture.

Conventional photobioreactors for microalgal mass culture requires are expensive and cunsume high energy. Additionally, high temperature and strong sunlight in tropical regions cause growth inhibition and damage to bioreactors. To overcome these issues, a novel floating bioreactor will be innovated taking into account cost performance and energy efficiency.

Recycle nutrients for microalgae and
protect the sea.

Current aquaculture practices involves discharging large volumes of wastewater into the aquatic ecosystems, causing pollution and loss of biodiversity. On the other hand, the wastewater contains valuable nutrients that can be recycled for microalgae production. This recycling system assures high-value microalgae production, protection of the environment and sustainable aquaculture practice.

Utiliza high-value resources
from microalgae.

Microalgae are not only potential bioenergy resources, but also a source of high-value substances such as unsaturated fatty acids (e.g., EPA and DHA) and antioxidants (e.g., astaxanthin and B-carothene). We employ the newly established system to culture selected high-value microalgae and develop value-added products such as pharmaceuticals, cosmeceuticals, nutraceuticals, functional feeds (e.g., aquaculture and livestocks) and many others.

What is SATREPS and the COSMOS projects?

SATREPS is a government-sponsored program supported through the collaboration between Japan International Cooperation Agency (JICA) and Japan Science and Technology Agency (JST), which promotes imternational joint research. Under SATREPS, COSMOS is an international collaboration amongest seven institutions from Japan and Malaysia. COSMOS focuses on research and capacity building in developing sustainable aquaculture practices through recycling technologies.
