Considering the importance of lignocellulose macrophyte-derived for the energy flux in aquatic ecosystems and the nutrient concentrations as a function of force which influences the decomposition process, this study aims to relate the enzymatic activity and lignocellulose hydrolysis in different trophic statuses. Water samples and two macrophyte species were collected from the littoral zone of ...

In the artificial pearl industry, the epithelial cell of mantle grafting proliferates to form the pearl sac and secret organic matrix to guide pearl biomineralization. This article summarized the process of pearl formation, the involvement of matrix proteins in calcium carbonate (CaCO3) deposition and the genetic contribution of saibo in pearl formation. At last summarizes the existing issues a...

Using alkali-metal cation-substituted zeolites and 2,4,6-trihydroxyacetophenone (THAP), which is a typical organic matrix molecule for matrix-assisted laser desorption ionization (MALDI), mass spectrometry has been performed for maltohexaose and acetylsalicylic acid, and the cation-selective ionization of these analytes was achieved. It is found that a complex of cation-substituted zeolite and ...

Scleractinia coral skeleton formation occurs by a heterogeneous process of nucleation and growth aragonite in which intraskeletal soluble organic matrix molecules, usually referred to as SOM, play key role. Several studies have demonstrated that they influence the shape polymorphic precipitation calcium carbonate. However, structural aspects occur during received less attention. In this researc...
