Bioactivity of four Nostoc strains: perspective of exploitation in agriculture

Since the first green revolution the diffusion and massive use of agrochemicals have caused multiple ecological damages. To achieve food security and counteract negative effects of the increased exposure to abiotic stresses and spread of pests, the search for sustainable sources of plant growth promoters and plant protection products is crucial. In this work, the study of the bioactivity spectrum of four Nostoc strains on different target organisms of agricultural interest led to the identification of one strain with biostimulant activity, partial antibacterial activity and antifungal activity.
