Actinomycetales is an order of bacteria known for their filamentous structure and ability to form branching filaments. These bacteria are primarily found in soil and play a crucial role in decomposing organic matter, contributing to nutrient cycling in ecosystems. Many members of Actinomycetales are also known for their ability to produce antibiotics, such as streptomycin and tetracycline, which are important in medicine for treating bacterial infections. This order includes well-known genera like Streptomyces, which is extensively studied for its diverse metabolic capabilities and potential applications in biotechnology.
