The interest in eco-friendly, sustainable and organic farming cater high yield and quality in sustainable agriculture so as to relieve food scarcity. The plant growth and health promoting bacteria (PGHPR) are able to produce phytohormones and biosurfactants as effector metabolites in plant- microbe interactions and phyto-stimulation for their exploitation in agro-ecosystem. Bacterial phytohormones and biosurfactants are vital for plant growth and development, trigger nutrient availability, root colonization and imparting protection from phytopathogens in rhizosphere. This volume entitled “Bacterial Metabolites in Sustainable Agroecosystem” depicts various aspects of bacterial metabolites overtook on quest of research and concept up-gradation that can build emerging paradigm of future “Green Revolution”.
