order Actinomycetales
Học thuậtThân thiện
Definition
- Noun:
- A taxonomic order of bacteria: "Order Actinomycetales" refers to a specific scientific classification (order) of bacteria that are typically filamentous or rod-shaped in form. This order historically included many important bacteria, though taxonomic revisions have occurred.
Usage
- Scientific Classification: Used primarily in microbiology and taxonomy to categorize a group of bacteria.
- The bacterium Streptomyces, a prolific producer of antibiotics, was once classified within the order Actinomycetales.
- Modern phylogenetic studies have led to the reclassification of many members formerly placed in the order Actinomycetales.
Advanced Usage
- Historical Taxonomic Context: The term is often used in historical or traditional contexts, as many bacteria formerly in this order are now classified under different taxonomic groups based on genetic analysis.
- The order Actinomycetales, as originally defined, contained both aerobic and anaerobic species.
Variants and Related Words
- Actinomycete (n): A common name for bacteria belonging to this group or its descendants, often referring to their branching, fungus-like filaments.
- Actinomycetes are important in soil ecology and medicine.
- Actinomycetales (n): The same term, often used without "order" in scientific literature.
- Studies on Actinomycetales have revealed diverse metabolic capabilities.
Synonyms
- Actinomycete bacteria: A descriptive synonym focusing on the bacterial type.
- Filamentous bacteria: A broader, descriptive term for bacteria with a similar growth form.
Related Phrases
- Member of the Actinomycetales: A phrase used to describe an organism's historical taxonomic placement.
- This soil isolate is a member of the Actinomycetales.
Notes
- This term is highly specialized and used almost exclusively in scientific contexts, particularly microbiology, taxonomy, and medicine. Its usage reflects the evolving nature of bacterial classification.
Noun
- filamentous or rod-shaped bacteria
