Wine microbial diversity and cross-over applications: emerging results and future perspectives

Abstract

AIM: Cross-over applications are an emerging technological approach in food microbiology where a microorganism from one traditional specific fermentation process is used to improve quality and safety in another agri-food production/chain (Dank et al., 2021). A complex microbial diversity is found in association with fermentation in wine, including Saccharomyces, non-Saccharomyces and malolactic bacteria,  all microorganisms versatile in terms of enological utilisation (Tempère et al., 2018). Here, we propose a systematic literature review highlighting the existing trends and possible future applications related to cross-over exploitation of wine-related microbiota.

METHODS: Systematic review of the scientific literature, including the evaluation of data from ongoing research projects (‘INVISPUBA’, ‘SPUMAPULIA’ and ‘BE^2R projects, funded by Apulian Region throughout P.S.R. 2014/2020 -Misura 16.2).

RESULTS: For decades, a continuous effort has been carried out worldwide to preserve and exploit the microbial diversity associated with traditional wines and Geographical Indications, including studies on specific autochthonous grape varieties. The oenological significance of an impressive number of eukaryotic and prokaryotic strains have been assessed, including their effects on dessert, flor and sparkling wines. Often these biological resources are preserved in culture collections, favouring exchanges in food uses (De Vero et al., 2019). The review proposes an overview of the phenotypic characteristics of wine microbes of potential interest for the design of cross-over strategies, with the desired modulation of ‘food qualities’ and safety enhancement. The application of wine strains as a sustainable driver of innovation in other fermented foods (e.g. bread) (Capozzi et al., 2016), alcoholic beverages (e.g. bread and fruity wines) (Agarbati et al., 2020; Canonico et al., 2021; Vilela et al., 2020), and for the development of new fermented products is discussed.

CONCLUSIONS: The proposed overview of the scientific literature i) underlines a high potential of innovation related to wine ‘microbiodiversity’ and ii) emphasises the importance of culture collections in the light of cross-over applications. The review also underlines the chance to explore innovative regional paths exploiting the exchange of microbial resources from traditional fermented products to other agri-food chains.

Rootstock mediated responses of grapevine (Vitis vinifera L.) metabolism and physiology to combined water deficit and salinity stress in Syrah grafts

Water deficit and salinity are increasingly affecting the viticulture and wine industry. These two stresses are intimately related; understanding the physiological and metabolic responses of grapevines to water deficit, salinity and combined stress is critical for developing strategies to mitigate the nega- tive impacts of these stresses on wine grape production. These strategies can include selecting more tolerant grapevine cultivars and graft combinations, improving irrigation management, and using soil amendments to reduce the effects of salinity. For this purpose, understanding the response of grape- vine metabolism to altered water balance and salinity is of pivotal importance.

Vignobles sur les pentes en Bourgogne : l’aube d’un nouveau modèle de l’Antiquité au Moyen Âge

La découverte d’une vigne gallo-romaine en plaine à Gevrey-Chambertin (Côte-d’Or) constitue un point important pour la compréhension de la construction des terroirs viticoles de Bourgogne. Sa situation en plaine constitue pour nous le point de départ d’une large réflexion sur la mise en place du modèle de viticulture de coteau qui prévaut en Bourgogne et sur les facteurs de ce changement de norme de qualité viticole. Les sources mobilisées pour cette approche interdisciplinaire et diachronique sont géomorphologiques, archéologiques et textuelles.

Diagnosis of soil quality and evaluation of the impact of viticultural practices on soil biodiversity in a Southwestern France vineyard

The soil plays a pivotal role in the agroecological transition processes, due to its numerous implications in production support, water regulation, air and nutrient supply, and its function of reservoir for the major part of planet biodiversity. Therefore, soil quality and adequate soil management are key levers for an ecologically and economically sustainable viticulture. Gascogn’Innov (2017-2022) is an Operational Group funded by the European Innovation Partnership for Agriculture. As such, it gathered winegrowers from the south-west of France (Gascony), scientists, advisors and technicians, around a project focused on the biological functioning of viticultural soil and the design of better-adapted technical paths for soil protection.

Intra-varietal diversity in cv. ‘Tempranillo Tinto’: phenological stages

‘Tempranillo Tinto’ is one of the most relevant grapevine cultivars worldwide. Despite its early ripening and relatively short vegetative cycle, which may not be ideal for high-quality grape and wine production in warming conditions, its long-standing cultivation has led to an intense multiplication by cuttings, which originated the high level of clonal variation currently available. Now, this intra-varietal diversity provides an interesting opportunity for cultivar improvement by identifying genotypes with better adaptation potential.
