Streptomyces behavior and competition in the natural environment

Streptomyces are ubiquitous terrestrial bacteria that are renowned for their robust metabolic capabilities and their behavioral flexibility. In competing for environmental niches, these bacteria can employ novel growth and dispersal behaviors. They also wield their diverse metabolic repertoire for everything from maximizing nutrient uptake, to preventing phage replication or inhibiting bacterial and fungal growth. Increasingly, they are found to live in association with plants and insects, often conferring protective benefits to their host courtesy of their ability to produce pathogen-inhibitory antimicrobial compounds. Here, we highlight recent advances in understanding the competitive and cooperative interactions between Streptomyces and phage, microbes, and higher organisms in their environment.
