Les changements climatiques ne sont plus à prouver. Les sécheresses estivales sont une des conséquences mettant le plus à mal l’écosystème forestier. Face à la rapidité de ces modifications, une des solutions proposées pour accroitre la résilience des forêts est l’utilisation d’essences exotiques. Ces espèces introduites hors de leur aire de distribution naturelle sont-elles réellement la solution à l’équation ? Cette étude a pour but de discuter des potentialités et des risques de l’introduction du cèdre de l’Atlas en Belgique. Cet arbre réputé pour sa tolérance à la sécheresse est un candidat intéressant face aux problèmes actuels. Cependant, la prudence et la lucidité doivent être de mise. En effet, les essences exotiques ne sont pas exemptes de défauts et une analyse de risque est obligatoire pour ne pas aggraver la situation. C’est pourquoi, dans ce travail de fin d’étude, en plus de la littérature scientifique existante, plusieurs démarches ont été réalisées afin d’apporter différents éléments de réponses. Les objectifs de cette étude sont donc multiples : 1) Réaliser un monitoring dans les jeunes parcelles de cèdres actuelles afin de tirer des conclusions sur leurs croissances et leurs états de santé ; 2) Prévoir une potentielle propagation d’un agent pathogène dans les forêts wallonnes due à l’introduction du cèdre de l’Atlas : cas du Sirococcus tsugae ; 3) Prévoir un potentiel nouvel agent pathogène sur cet arbre : cas du Sirococcus conigenus. Les résultats ont montré qu’actuellement le cèdre se porte bien en Wallonie Une bonne production et un bon état de santé sont observés. Cependant, la pression du gibier et la sensibilité à la dominance sont les deux éléments qui ont causé les plus grands problèmes jusqu’ici. Concernant la première expérience d’inoculation, le cèdre, le tsuga et le mélèze semblent être fort sensibles à S. tsugae. Pour ce qui est de la deuxième, S. conigenus ne semble pas être un problème pour le cèdre même si quelques nécroses ont été observées. Il est vrai que le cèdre est un arbre avec des potentialités fortes intéressantes mais son introduction doit être limitée. En effet, des risques tels qu’une potentielle invasivité ou le manque de co-évolution ne sont pas quantifiable à l’heure actuelle. Les quelques plantations présentes en Belgique doivent donc servir de parcelles sentinelles et un suivi dans le temps est obligatoire afin de suivre l’évolution et l’adaptation de cette essence. Climate change is a proven fact. Summer droughts are one of the most damaging consequences for the forest ecosystem. Given the rapidity of these changes, one of the solutions suggested to increase the resilience of forests is the use of exotic species. Are these species introduced out of their natural area really the solution to the equation ? The aim of this study is to discuss the potentialities and risks of the introduction of Atlas cedar in Belgium. This tree, known for its drought’s resistance, is an interesting contender in the face of current problems. However, caution and lucidity must not be forgotten. Indeed, exotic species are not free of defects and a risk analysis is mandatory in order to not make thing worse. This is why, in this study, in addition to the existing scientific papers, several steps have been taken in order to provide different elements of answers. Aims of this study are multiple: 1) To carry out a monitoring in the young plots of cedars to draw conclusions on their growth and health status ; 2) To predict a potential propagation of a pathogen due to the introduction of Atlas cedar: case of Sirococcus tsugae ; 3) To predict a potential new pathogen on this tree: case of Sirococcus conigenus. These results showed that cedar is currently doing well in Wallonie. A good wood production and a good state of health are observed. However, game pressure and susceptibility to dominance are the two elements that have caused greatest problems so far. Concerning the first inoculation experiment, cedar, western hemlock and larch seem to be very sensitive to S. tsugae. Concerning the second, S. conigenus does not seem to be a problem for cedar although some necrosis has been observed. It is true that the Atlas cedar is a tree with interesting strong potential but its introduction should be limited. Indeed, risks such as potential invasiveness or lack of co-evolution are not quantifiable now. The few plantations present in Belgium must be therefore serve as sentinel plots and monitoring over time is mandatory in order to follow the evolution and adaptation of this species.

Yeasts are truly fascinating microorganisms. Due to their diverse and dynamic activities, they have been used for the production of many interesting products, such as beer, wine, bread, biofuels and biopharmaceuticals. Saccharomyces cerevisiae (bakers’ yeast) is the yeast species that is surely the most exploited by man. Saccharomyces is a top choice organism for industrial applications, although its use for producing beer dates back to at least the 6th millennium BC. Bakers’ yeast has been a cornerstone of modern biotechnology, enabling the development of efficient production processes for antibiotics, biopharmaceuticals, technical enzymes, and ethanol and biofuels. Today, diverse yeast species are explored for industrial applications, such as e.g. Saccharomyces species, Pichia pastoris and other Pichia species, Kluyveromyces marxianus, Hansenula polymorpha, Yarrowia lipolytica, Candida species, Phaffia rhodozyma, wild yeasts for beer brewing, etc. This Special Issue is focused on recent developments of yeast biotechnology with topics including recent techniques for characterizing yeast and their physiology (including omics and nanobiotechnology techniques), methods to adapt industrial strains (including metabolic, synthetic and evolutionary engineering) and the use of yeasts as microbial cell factories to produce biopharmaceuticals, enzymes, alcohols, organic acids, flavours and fine chemicals, and advances in yeast fermentation technology and industrial fermentation processes.

It has been over 200 years since Fusarium pathogens were described for the first time, and they are still in the spotlight of researchers worldwide, mostly due to the mycotoxigenic abilities and the subsequent introduction of harmful metabolites into the food chain. The accelerating climatic changes are resulting in pathogen population and chemotype shifts all around the world, thus increasing the demand for continuous studies of factors that affect the virulence, disease severity and mycotoxin accumulation in plant tissues. This Special Issue summarizes recent advances in the field of Fusarium genetics, biology and toxicology.

During the last few years, industrial fermentation technologies have advanced in order to improve the quality of the final product. Some examples of those modern technologies are the biotechnology developments of microbial materials, such as Saccharomyces and non-Saccharomyces yeasts or lactic bacteria from different genera. Other technologies are related to the use of additives and adjuvants, such as nutrients, enzymes, fining agents, or preservatives and their management, which directly influence the quality and reduce the risks in final fermentation products. Other technologies are based on the management of thermal treatments, filtrations, pressure applications, ultrasounds, UV, and so on, which have also led to improvements in fermentation quality in recent years. The aim of the issue is to study new technologies able to improve the quality parameters of fermentation products, such as aroma, color, turbidity, acidity, or any other parameters related to improving sensory perception by the consumers. Food safety parameters are also included.

Nowadays, 25% of materials used are metals, and this ratio is not expected to decrease, as metals are indispensable for many applications due to their high resistance to temperature. The only handicap of metals is their relatively higher density with respect to composites. Lightening of metallic structures is possible in three ways: (i) employing low density metals, (ii) developing new ones, and (iii) increasing the yield strength of existing high-density metals. The Laboratory of Excellence of the Lorraine University in France, called ‘Design of Alloy Metals for Low-Mass Structures’, is working to lighten metal via metallurgical means. Two leading research laboratories compose this Laboratory of Excellence within the Lorraine University: the Laboratory of Microstructure Studies and Mechanics of Materials (LEM3), based in Metz, and the Jean Lamour Institute (IJL), located in Nancy. In this Special Issue, they report on some of their major progress in the different fields of metallurgy and mechanics of metallic materials. There are articles in the three major fields of metallurgy: physical, chemical, and mechanical metallurgy. All scales are covered, from atomistic studies to real-scale metallic structures.
