OUR RESEARCH FOCUS

Soil Stabilization

Soil Reinforcement Applying MICP to improve the mechanical properties of loose sandy soil, increasing shear strength and load-bearing capacity for ground improvement.

Bio-Bricks

Sustainable Bio-Construction Materials Developing unfired "bio-bricks" using bacteria and sand. This process eliminates the need for high-temperature kilns, significantly reducing CO2 emissions.

Coral Restoration

Artificial Reefs & Marine Restoration Utilizing the natural calcification process to create eco-friendly artificial substrates that support coral attachment and marine ecosystem recovery.

PROJECT OF 2026-2027

Investigation of Carbonate Precipitation by Sporosarcina pasteurii DSM33 in Saline Conditions using Oyster Shell-Derived Calcium

Objective

To evaluate the calcification efficiency of S. pasteurii in high-salinity environments using a sustainable calcium source extracted from discarded oyster shells, aiming to replace expensive industrial chemicals like Calcium Chloride (CaCl2).

Methodology

Calcium Extraction: Treating waste oyster shells with acid to recover Calcium ions (Ca2+).
Bacterial Acclimatization: Culturing S. pasteurii in media with varying salinity levels (simulating seawater or saline soil).
Precipitation Test: Measuring calcite production and analyzing crystal morphology using SEM/XRD.

Significance

Waste Valorization: Transforming seafood waste into valuable construction resources.
Cost Reduction: Lowering the material cost of the MICP process.
Marine Application: Opening potential for bio-consolidation in coastal and marine environments.
