Functional Pearl-like Multilayer Nanomaterials
Efficient and Eco-friendly Mass Production via Yeast and Koji Mold Fermentation
Overview
This invention presents a new platform for creating organic-CaCO₃ composite materials with pearl-like multilayer nanostructures using a bio-manufacturing process involving yeast and koji mold.
Building on prior research into the bio-mineralization of Pteria penguin pearls, the inventors have successfully expressed the related proteins and enzymes in yeast to produce highly controlled multilayer CaCO₃ crystals.
💎 High-Performance Materials ：By optimizing the expression of matrix proteins and enzymes, the crystal structure and material properties can be precisely controlled.
🌱 Sustainability ：The fermentation-based production process enables large-scale manufacturing with minimal environmental impact and low cost.
