Abstract

Lignin is the natural glue in plants to provide its strength and resistance against microbial decay and playsan important role in the water transport in the plant's vascular tissue. Through its aromatic structure andfunctionalities, lignin exhibits a variety of properties serving as a renewable feedstock for the production ofbiofuels, materials and bio-based aromatic specialty chemicals. Moreover, the global limitation of fossilpetrochemical resources should increase the awareness that lignin represents the only available largevolume source of aromatics apart from fossil based resources, and which is not in direct competition withthe food production. Therefore lignin has the potential to become a future raw material for industry.However, as a co-product of the pulp & paper industry and cellulosic ethanol production, the potential oflignin is currently largely underexploited, mainly due to its complex structure.Currently, the base case for lignin side streams is to use it simply as an internal energy source in the pulpingand biorefinery industries. The need for cost-effective and sustainable production of 2nd generation sugarstreams for the biotech industry, as well as improvements in energy efficiency (leading to a lignin surplus),is driving the urgently look for novel economic valorisation of lignin. The industry is more and moreconvinced that economic valorisation of this aromatic side stream is absolutely essential to make theprocessing of lignocellulosic feedstocks market competitive. To unlock the potential of lignin, aninterdisciplinary and cross sectorial approach is needed by grouping relevant expertises within one pan-European network to tackle and overcome the challenges faced in industrial lignin valorisation. LignoCOSTbrings together partners with outstanding and complementary expertises, active over the whole ligninvalue chain, including plant breeding, lignin production, characterization, fractionation, modification,depolymerization and application.The main objective of LignoCOST is to establish a sound network covering the entire value chain in whichrelevant information will be produced with a focus on lignin valorisation to stimulate the increase ofsustainable industrial applications. Only when working together this information can be gathered to coverthe technical, non-technical, environmental and socio-economic implications of the most promising ligninvalue chains.LignoCOST started in October 2018 with about 120 participants coming from 33 countries. In January2020 LignoCOST consists of more than 250 participants representing 43 countries from Europe, Canada,US, New Zealand, and South Africa. This COST network gains a lot of attention from the different valuechain actors interesting in lignin valorisation. Not only research organisations, but also companies areconnected in this network. Currently, over 20 companies are participating to this network. LignoCOSTorganised several networking events, over 20 short term scientific missions, and stimulate the cooperationbetween partners resulting in joint publications, conference presentations and posters.In this presentation the status, progress and achievements of LignoCOST will be presented.COST Action LignoCOST (CA17128) is supported by COST (European Cooperation in Science andTechnology), in promoting interaction, exchange of knowledge and collaborations in the field of ligninvalorisation.

Abstract

A new biobased material based on an original strategy using lignin model compounds as natural grafting additive on a nanocellulose surface through in situ polymerization of coniferyl alcohol by the Fenton reaction at two pH values was investigated. The structural and morphological properties of the materials at the nanoscale were characterized by a combination of analytical methods, including Fourier transform infrared spectroscopy, liquid chromatography combined with mass spectrometry, nuclear molecular resonance spectroscopy, electron paramagnetic resonance spectroscopy, water sorption capacity by dynamic vapor sorption, and atomic force microscopy (topography and indentation modulus measurements). Finally, the usage properties, such as antioxidant properties, were evaluated in solution and the nanostructured casted films by radical 2,2′-diphenyl-1-picrylhydrazyl (DPPH•) scavenging tests. We demonstrate the structure–function relationships of these advanced CNC-lignin films and describe their dual functionalities and characteristics, namely, their antioxidant properties and the presence of persistent phenoxy radicals within the material.

Abstract

The existence of pilot and industrial scale biorefineries worldwide demonstrates the technical andeconomic feasibility of fractionating lignocellulose (LC) for chemistry and energy. This raisesnew questions about the biomass supply, management of its quality and about the elementary stepcombination in processes, to choose which compound will be main- or co-products from plantbiomass.Integrated and systemic approaches are requested to invent and/or to improve the biotechnicalfractionation of LCs and there is a need to collect and correlate the existing knowledge in astructured way, to gain a better insight of the overall process. Building such a knowledgerepresentation is important for scientists, research institutes, universities and industries, as it willgive a shared description of the knowledge in that field, that will further facilitate its diffusion,re-use, review, reassessment and updating with new findings.Practically, an extensive literature has been published in the past five years on the biorefinery ofLC, focusing mostly on the saccharification of polysaccharides (cellulose, hemicellulose). As aconsequence, most of the data available results from biochemical and physicochemical analyzesfrom several processing chains, which combine different modes of physical pretreatments and/orchemical typologies of variables biomass and/or various hydrolytic enzyme cocktails.That is why a project for development of a hypertext electronic Knowledge Book onLignoCellulose DeConstruction (KB-LCDC) was initiated by the French National Institute forAgricultural Research (INRA) with two main goals: i/ to elicit the available knowledge fromvarious sources, more specifically related to the enzymatic hydrolysis of wheat straw intoglucose, ii/ to represent the knowledge and implement it into a web-based format of KnowledgeBook (KB) taking into account the overall saccharification process.The knowledge was first elicited by means of semi-structured interviews with a group of sixexperts working in several INRA research Units, and involved in the Institute’s biomass transformation network. Concomitantly, the collating of data and knowledge from “grey-” andpeer reviewed- literature was also done.Then, our approach consists in building a knowledge book (KB) whose pages are formattedconcept maps (Cmap) and technical sheets that are connected by hypertext links. A Cmap is asemantic graph where nodes represent concepts that are connected by arcs expressingrelationships between them. A formatted Cmap answers a specific question about one centralconcept (for instance: what is the impact of the pretreatment on the reactivity of biomass ? Howdoes enzyme diffuse into the lignocellulose ?). Hyperlinks existing between Cmaps and technicalsheets form a network of knowledge, into which the user can navigate, to find relevant answers,but also associated concepts. Hyperlinks can also link Cmaps or technical sheet to an Internetpage, scientific article and any document selected to illustrate the reality of a concept.Up to nine knowledge areas have been identified so far, among them: biomass pretreatment;separation methods; enzyme cocktails; substrate reactivity, hydrolysis mechanisms. A globalrepresentation of the overall process from wheat straw to glucose, based on the individual Cmaps,has been built. It includes a static structural view (environment and reactivity of the media,encompassing the cell wall); a dynamic view (hierarchy of the different sub-processes at work)and a functional view (description of the elementary steps and how they are organized in time).In the frame of the LBT III congress, the practical structuration of the knowledge and the originalversion of the KB will be disclosed. The potential development and use of this new approach forthe representation of biotechnology processes applied to LC will be discussed (process workflow;unlocking cell wall recalcitrance; strategic roadmaps).

Abstract

Oxalate is a common metabolite produced by almost all plant-pathogenic fungi. The degradation of cell wall from poplar chips and poplar sawdust by oxalate is reviewed here. Oxalate treatments decrease slightly the amount of sugars constituting hemicelluloses, but only in fibres and not in sawdust or wood chips. The examination of the cell wall ultrastructure of wood chips by transmission electron microscopy (TEM) after polysaccharide staining showed a characteristic fading of the staining of the S1/S2 and S2/S3 transition areas, supporting the idea that reactivity and organization of polysaccharides had changed after the oxalate treatments. Finally, all these changes enhanced the ability of the wood chips to be defibrated by a thermomechanical (TMP) process, as well as the further refining of the pulps. Looking at the fiber surface, it became apparent that fracture areas during the TMP pulping had moved toward the S2 layer, explaining why defibrating and refining occurred more easily, with less energy input in the process.
