Control of Bacteria for Sustainable Viticulture and Vinification Practices

Vitis sp. diseases are a constant threat to wine production and quality. At the same time, consumers’ demand for organoleptically superior wines that should result from sustainable practices both in vineyards and in wineries is increasing. Thus, the development of efficient practices to regulate the microbiome of grapevines and wine fermentations is more than urgent and relevant. This PhD thesis is divided into two parts. One part concerns Pierce´s disease, a serious grapevine disease caused by the bacterium Xylella fastidiosa subsp. fastidiosa. Different control strategies have been suggested for the protection of vineyards from Pierce´s disease. In order to aid control efforts, this thesis has gathered all different concepts of control interventions and has explored the potential of these concepts by means of an epidemiological model. The second part of the thesis focuses on the versatile bacterium Lactobacillus plantarum. Many studies have demonstrated the crucial role that L. plantarum plays in human health (probiotic), agriculture (biocontrol agent of phytopathogens, plant-growth biostimulator) and in the food industry (food preservative, fermentation starter, food spoiler). With a view to identifying natural enemies of L. plantarum, this thesis has isolated and characterised viruses (bacteriophages) infecting wine-related strains of the bacterium.
