Abstract:
... Wood is a natural and clean material with lightweight and satisfactory mechanical properties and has been widely used at present. In order to better understand the relation between the anatomical properties and the tribological properties of wood, three representative kinds of wood have been used for experiments. The anatomical structure, extractives combined with the mechanical properties of the ...

Abstract:
... The study of peptidoglycan-binding proteins frequently requires in vitro binding assays, in which the isolated peptidoglycan used as a substrate must be carefully quantified. Here, we describe an easy and sensitive assay for peptidoglycan quantification based on a modified Nelson–Somogyi reducing sugar assay. We report the response of this assay to different common sugars and adapt its use to pept ...

Abstract:
... BACKGROUND: Substrate accessibility remains a key limitation to the efficient enzymatic deconstruction of lignocellulosic biomass. Limited substrate accessibility is often addressed by increasing enzyme loading, which increases process and product costs. Alternatively, considerable efforts are underway world-wide to identify amorphogenesis-inducing proteins and protein domains that increase the ac ...
