Biocontrol of phytopathogenic fungi by aquatic actinobacteria

Abstract

Among microbial control agents, actinobacteria are of particular interest due to their ability to produce antimicrobial compounds and inhibit numerous phytopathogens. Effective strains have been reported in the genera Actinomadura, Actinoplanes, Arthrobacter, Micromonospora, Rhodococcus, and Streptomyces. Their metabolic versatility allows them to compete in root exudates and plant litter, colonize the rhizosphere and plant tissues, and form stable plant associations [2]. Aquatic actinobacteria also contribute to water quality improvement, pathogen suppression, and the health of aquatic organisms. Aim of the study: This study aimed to screen actinobacteria strains isolated from the Lake La Izvor system for their ability to inhibit the growth of phytopathogenic fungi.
