Feeding amylolytic and fibrolytic exogenous enzymes in feedlot diets: effects on ruminal parameters, nitrogen balance and microbial diversity of Nellore cattle

Journal of Animal Science and Biotechnology
Background The environmental impact of feedlot operations is a growing concern, as cattle excrete a significant portion of feed nutrients as waste.

Construction and characterization of bifunctional fibrolytic enzymes

, 2013
植物的細胞壁主要由纖維素、半纖維素與木質素等構成，而這種複雜的結構較不易被單一纖維分解酵素所分解，進而造成利用上的困難，因此近年來許多研究利用基因工程技術融合多種纖維素分解酵素或半纖維素分解酵素基因，建構出具雙功能或多功能之纖維分解嵌合酵素，與單一功能纖維分解酵素相比，多功能或雙功能纖維分解酵素除了可提升分解植物細胞壁纖維的效率之外，在酵素製程方面亦節省了時間與金錢成本。 本研究係將兩段分別由瘤胃真菌Piromyces rhizinflatus選殖出的β-聚葡萄糖酶 (β-glucanase ...

Extracellular enzymes in bioremediation: potential and limitations

, 2016
Bioremediation processes often pivot on the activity of living organisms such as microorganisms, plants, algae. Bioremediation of contaminated soil and water finds very efficient tools in extracellular enzymes.
