Background The mechanical properties of parenchyma cell walls and the strength and extension of adhesion areas between adjacent cells, jointly with cell turgor, are main determinants of firmness of fleshy fruits. These traits are modified during ripe

Extracellular vesicles released by the human gut symbiont Bacteroides thetaiotaomicron in the mouse intestine are enriched in a selected range of proteins that influence host cell physiology and metabolism

It is becoming increasingly clear that bacterial extracellular vesicles (BEVs) produced by members of the intestinal microbiota can contribute to microbe-host cell interactions that impact on host health. A major unresolved question is the nature of

There is great interest in understanding changes that occur to cell wall constituents during saccharification of pretreated lignocellulose, particularly in relation to recalcitrance of the residues. This paper reports the effects of hydrothermal pret

Autor: A. Patrick Gunning, Simon M. Loveday

Publikováno v: Biomacromolecules. 19(7)

Nanofibrils of β-lactoglobulin can be assembled into bundles by site-specific noncovalent cross-linking with high-methoxyl pectin (Hettiarachchi et al. Soft Matter 2016, 12, 756). Here we characterized the nanomechanical properties of bundles using
