branched gram-positive bacteria, often found in soil, some of which are pathogenic for humans and animals.
Any of a group of generally low-oxygen–utilizing bacteria identified by a branching growth pattern that results in large threadlike structures. Many species occur in soil and are harmless to animals and higher plants.
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.
a fungus-like soil microoganism needed in the decay of organic matter like regular mushrooms.
A family of non-disease-causing bacteria that produce a wide range of drugs and other useful bioactive molecules.
Any of various filamentous, mostly anaerobic bacteria.
Filamentous bacteria that produce several antibiotics and give soil its earthy smell.
Any one of a group of bacteria found in soil that are structurally similar to certain fungi. Antibiotics such as streptomycin and chloramphenicol are derived from some actinomycetes.
(literally "ray fungi") filamentous bacteria that have sometimes been classified as Fungi Imperfecti. Actinomycetes typically are saprobes (especially in soil) but a few are pathogenic to man, animals, and plants. ()
Soil microorganisms intermediate between bacteria and fungi.
A group of organisms intermediate between the bacteria and the true fungi, mainly resembling the latter because they usually produced branched mycelium.
Decay microorganisms that have a fungus-like appearance but, like bacteria, do not contain a well defined nucleus.
A large group of bacteria that grow in long filaments that are too small to see without magnification. Actinomycetes generate the smell of “healthy soil,” and are important in decomposing cellulose, chitin, and other hard-to-decompose compounds, especially at higher pH levels. Many produce antibiotics.
