Particle size of straw and gelation of pectin influence gastric mixing and emptying in pigs.

Physicochemical properties of fibres can strongly impact gastric processes such as emptying and sieving. This study evaluated the influence of particle size of insoluble fibres, and gelation of soluble fibres when added to insoluble fibres, on gastric emptying of digesta phases from the proximal and distal stomach of pigs. Twenty-four boars (51.

Effect of substrate size reduction and periodic nutrient supplementation on biological wood oxidation.

Biological wood oxidation (BWO) is a composting heat recovery system tailored for woody lignocellulose valorization, with the potential to generate sustainable and low-temperature heat. This study investigated the effects of feedstock particle sizing and periodic nutrient supplementation (PNS) on microbial activity and wood decomposition during BWO. Birch wood was processed into sawdust (<5 mm) and cubes of various diameters (5, 10, and 15 mm), incubated in batch-mode BWO reactors for 88 days, and periodically supplemented with a nutrient medium.

Salt stress alters the cell wall components and structure in Miscanthus sinensis stems.

Miscanthus is a perennial grass suitable for the production of lignocellulosic biomass on marginal lands. The effects of salt stress on Miscanthus cell wall composition and its consequences on biomass quality have nonetheless received relatively little attention. In this study, we investigated how exposure to moderate (100 mM NaCl) or severe (200 mM NaCl) saline growing conditions altered the composition of both primary and secondary cell wall components in the stems of 15 Miscanthus sinensis genotypes.

Particle size of insoluble fibres and gelation of soluble fibres influence digesta passage rate throughout the gastrointestinal tract of finishing pigs.

Fibres, as abundant in agricultural by-products, exhibit a large range of physicochemical properties that can influence digestive processes such as digesta mean retention time (MRT), thereby affecting nutrient digestion kinetics. In this study, we investigated the effects of particle size of insoluble fibres, and gelation of soluble fibres on MRT of liquids, fine solids, and fibrous particles in the different segments of the gastrointestinal tract (GIT) of pigs. Twenty-four boars (51.

From C-lignin to C-mycelium: uses polymeric lignin as a carbon source.

Plant biomass conversion by saprotrophic fungi plays a pivotal role in terrestrial carbon (C) cycling. The general consensus is that fungi metabolize carbohydrates, while lignin is only degraded and mineralized to CO. Recent research, however, demonstrated fungal conversion of C-monoaromatic compounds into proteinogenic amino acids.
