Los actinomicetos son un reservorio enorme de antibióticos y metabolitos bioactivos y muchos de ellos son excelentes agentes de biocontrol para proteger a las plantas contra fitopatógenos. Aunque miles de antibióticos y metabolitos bioactivos han sido descritos, se cree que estos representan solo una fracción de los compuestos bioactivos producidos por los actinomicetos. En esta revisión se abordan las características generales y propiedades de los actinomicetos como agentes de control biológico, sus mecanismos a través de los cuales realizan el biocontrol y el impacto de la composición química de la pared celular de los hongos fitopatógenos en el proceso de control.


Actinomycetes are an enormous reservoir for antibiotics and bioactive metabolites, and many are excellent biocontrol agents for use in protecting plants against phytopathogens. Although thousands of antibiotics and bioactive metabolites have been described, these are thought to represent only a small fraction of the bioactive compounds produced by actinomycetes. In this review, we summarize the general characteristics and properties of actinomycetes as biocontrol agents, the mechanisms through which the biocontrol occurs, as well as the impact of the phytopathogenic fungal cell wall composition in the control process.

Keywords: Streptomyces, competition, parasitism, antibiosis.
