![]() In vitro tests demonstrated the ability of these strains to produce siderophores, Indoleacetic acid (IAA), extracellular enzymes and solubilizing phosphate. glumae strains, as well as a wide range of bacterial and fungal species, while a third strain (7.1) showed only antifungal activity. Two isolates (A20 and 5.1) inhibited growth of virulent B. Additionally, the presence of other plant-growth promoting abilities and their possible beneficial effects upon their inoculation on rice plants was evaluated as an ecological analysis for their future inoculation in rice crops. In this study we describe the assessment of three Streptomyces isolates as biocontrol agents for B. 5Bacteriology and Plant Bacteriology Group, International Centre for Genetic Engineering and Biotechnology, Trieste, Italyīacterial Panicle Blight caused by Burkholderia glumae is a major disease of rice, which has dramatically affected rice production around the world in the last years.4Biotechnology Development Unit, International Centre for Genetic Engineering and Biotechnology, Trieste, Italy.Universidad Nacional de Colombia, Bogotá, Colombia ![]() 2Instituto de Biotecnología, Universidad Nacional de Colombia, Bogotá, Colombia.1Investigación y el Desarrollo, Biocultivos S.A., Bogotá, Colombia.Ramos 3, Corrado Guarnaccia 4, Giuliano Degrassi 5, Vittorio Venturi 5 and Nubia Moreno-Sarmiento 2* Zulma Rocío Suárez-Moreno 1*, Diana Marcela Vinchira-Villarraga 2, Diana Isabel Vergara-Morales 1, Leonardo Castellanos 3, Freddy A. ![]()
