A group of gram-positive bacteria (order Actinomycetales) that produce various bioactive agents including antibiotics, enzymes, and vitamins. Streptomyces belong to this bacterial order.

Group of filamentous microorganisms that are intermediate between bacteria and fungi.

Microorganisms that are half bacteria and half fungi. They do their breakdown work in a compost pile at temperatures ranging from 70 - 90 degrees.

formerly classified as fungi because of their filaments, the actinomycetales include many types of soil bacteria. They produce antibiotics, enzymes, and vitamins, although a few are harmful to humans.

Unicellular filamentous microorganisms that branch monopodially or more rarely dichotomously and form radiating colonies; mainly found in the soil, and cause of its characteristic odor.

Class of Bacteria with diverse morphological properties. Strains of ActinoBacteria show greater than 80% 16S rDNA/rRNA sequence similarity among each other and also the presence of certain signature N [..]

Filamentous bacteria that produce several antibiotics and give soil its earthy smell.

Any of a group of generally low-oxygen–utilizing bacteria identified by a branching growth pattern that result in large threadlike structures. Many species occur in soil and are harmless to animal [..]

A heterogeneous collection of bacteria that form branching filaments.

A filamentous bacteria that resembles fungi.

<bacteria> <microbiology> Gram-positive bacteria that can form branching filaments. They may form true mycelia or produce conidiospores. (13 Nov 1997)

Filamentous bacteria, many of which are valuable in the production of antibiotics.

Any of numerous, generally filamentous, and often pathogenic, microorganisms resembling both bacteria and fungi.
