[unpad.ac.id, 27/7/2018] Unpad is actively involved in a consortium of international research projects that identify the potential of the diatoms Haslea ostrearia in the aquaculture sector. The research project funded by the EU Agency Horizon 2020 which is attended by 21 universities from 12 countries in the world.
The “Genus Haslea, New Marine Resources for Aquaculture” or GhaNa (Ghana) project aims to explore the utilization of diatoms mareninne bioactive compound of Haslea ostrearia, a microalgae in the waters of various sectors.
Unpad researchers headed by Professor of Biochemistry from FMIPA, Prof. Dr. Toto Subroto, M.S., focuses on research related to ecophysiology and biochemical aspects. The consortium coordinated by Prof. Jean Luc-Mouget of Universite du Maine, Le Mans, France has divided every member country to work on specific research packages. Research has been ongoing from 2017 to 2021.
“(This research) develops new marine resources for blue biotechnology that focus on antimicrobial, aquaculture, biodiversity, cosmetics, ecophysiology, and others,” said Prof. Toto in the discussion of “Unpad Priority Research and Cooperation for Prosperous Society (Riung Karsa)” at Unpad Training Center, Bandung, Friday (27/7) afternoon.
Further Prof. Toto explained, mareninne compound is a blue pigment that is often used to green the shells in the western France. Green shells are much in demand especially among the nobility of European society. This is based on the hypothesis of the benefits of green shells for health.
Although it has been used as a natural shell dyes since the 18th century, no research has been able to solve the molecular structure of mareninne. The last recent study concluded mareninne as a glycoside. Through this consortium, Unpad goes further on smashing mareninne structure.
Together with two other Unpad researchers, Muhammad Yusuf, PhD, and Fiddy Semba Prasetya, PhD, Prof. Toto traced the structure of mareninne compounds and their role.
“We have made progress from this research,” Prof. said. Toto. Currently, the research is entering the stage for publication.
Successfully raising the economic value of shellfish, mareninne becomes an interesting study for science. One of the interesting functions of mareninne is its ability to be an antibiotic.
Mareninne compounds effectively increase endurance, especially in shrimp and shellfish larvae. During this time, continued Prof. Toto, shrimp seed or larvae are susceptible to death due to weak metabolism power against bacteria and virus attacks.
“Mareninne is expected to be applied in ponds or shrimp and shellfish cultivation,” Prof. said. Toto.
This research maintained marine biodiversity and its sustainability. The samples were taken from the sea and then were reproduced in the laboratory. “Thus, the ecosystem has been well maintained,” said Prof. Toto. *
