Cold-Active Lipase from the Ice Cave SC65A.3 Strain, a Promising Biocatalyst for Silybin Acylation.

Cold-active lipase from the psychrophilic bacterial strain SC65A.3 isolated from Scarisoara Ice Cave (Romania) was cloned and characterized as an extremophilic biocatalyst for silybin acylation. Structural analyses highlighted conserved motifs confirming a functional lipase and the presence of primary structure elements for catalysis at low temperatures.

Biocatalytic Strategy for Grafting Natural Lignin with Aniline.

This paper presents an enzyme biocatalytic method for grafting lignin (grafting bioprocess) with aniline, leading to an amino-derivatized polymeric product with modified properties (e.g., conductivity, acidity/basicity, thermostability and amino-functionalization).
