“…Interestingly, they demonstrated that bending tests can be used to estimate the cell wall thickness and that a core ring structure, with a cellular core of lower density than the outer shell, can significantly increase the bending resistance of plant stems. Similar conclusions were obtained by Deger et al thanks to numerical modelling [354]. These kinds of structures are similar to the structure of a flax stem and offer explanation for the extraordinary length to diameter ratio of this plant (Figure 12).…”

For the past 15 years, there has been tremendous and ever-increasing industrial and academic interest and technological material development concerning plant fibre reinforced composites.Plant fibres can be sourced from a multitude of natural agro-sources, with the preferred choice as a composite reinforcement material often being driven by abundance, geographical location, and historical use. While from a product designer's or engineer's point of view, all plant cell walls are 'similar', there is indeed substantial diversity in plant fibre cell walls. Indeed, a growing body of research demonstrates how cell wall mechanical behaviour is strongly linked to its *Manuscript structure, biochemical composition and the plant growing conditions. At the same time, significant progress has been realised on the knowledge of plant fibre cell wall reinforcement mechanisms in biocomposites. Here, we provide a holistic overview of the main types of plant cell walls used as reinforcements for polymer composites. By synthesising a large body of bibliographic data, we present and discuss the useful diversity in cell walls, illustrated by original schematics for clear comparison. The link between their structures and main properties, in constant link with potential associated composite, is specifically discussed. Then, the different fibre extraction and cultivation modes are discussed and compared, especially through an environmental assessment. We also show how a scientist's point of view on cell wall structure and associated experimental approach and use of characterisation techniques lead to distinct results; following a critical review, we make recommendations on appropriate characterisation techniques for a specific fibre. A final discussion concludes this work by highlighting the pertinent parameters that accurately define a composite reinforcement cell wall. The review will serve as a useful handbook reference for researchers in the field of bio-based materials, and will provide important insights to designers and engineers for appropriate selection of plant fibre cell walls for specific composite applications.

“…In addition, pig C had the highest UniFrac distance and IQR indicating large variation between DNA extracted from FAS and POW . The major components in diet fed to pig C are barley fines which are physically more granular and abrasive than wheat fines [ 39 ], and thus possibly contribute to additional physical shear in addition to the extraction method.…”

Evaluating DNA Extraction Methods for Community Profiling of Pig Hindgut Microbial Community

Recovery of high quality PCR-amplifiable DNA has been the general minimal requirement for DNA extraction methods for bulk molecular analysis. However, modern high through-put community profiling technologies are more sensitive to representativeness and reproducibility of DNA extraction method. Here, we assess the impact of three DNA extraction methods (with different levels of extraction harshness) for assessing hindgut microbiomes from pigs fed with different diets (with different physical properties). DNA extraction from each sample was performed in three technical replicates for each extraction method and sequenced by 16S rRNA amplicon sequencing. Host was the primary driver of molecular sequencing outcomes, particularly on samples analysed by wheat based diets, but higher variability, with one failed extraction occurred on samples from a barley fed pig. Based on these results, an effective method will enable reproducible and quality outcomes on a range of samples, whereas an ineffective method will fail to generate extract, but host (rather than extraction method) remains the primary factor.
