A New Family of Carbohydrate Esterases Is Represented by a GDSL Hydrolase/Acetylxylan Esterase from Geobacillus stearothermophilus*

Journal of Biological Chemistry, 2011
Background: Acetylxylan esterases are enzymes that remove acetyl groups from the hemicellulolytic polymer xylan. Results: The axe2 gene product in Geobacillus stearothermophilus removes acetyl groups from acetylated xylan and xylosaccharides. Conclusion:

Directed Evolution of an Efficient Polycarbonate Depolymerase With Exceptional Operational Stability

Angewandte Chemie International Edition, EarlyView.
Here, we show that well studied PET hydrolases can be re‐engineered via directed evolution to deconstruct alternative aromatic‐containing commodity polymers. Introduction of only three mutations into LCCICCG was sufficient to generate an efficient polycarbonate hydrolase with high operational stability that can fully depolymerize a polycarbonate sample

Exploring the Roles of Tuna‐Associated Acinetobacter sp. YFT067: Implications for Host Health and Metabolism

Animal Research and One Health, EarlyView.
This study firstly isolated a tuna‐derived gut probiotic Acinetobacter seifertii YFT067. Dietary administration of YFT067 played significant roles in promoting growth performance, SCFAs production, lipid absorption, and metabolism of the host, indicating YFT067 as a promising probiotic candidate for enhancing tuna aquaculture productivity through ...
