2. Growing organisms by themselves or in association with other completely known kinds of organisms; raising gnotobiotic organisms.
3. A condition in which all the forms of life present within an organism can be accounted for. Typically these organisms are germfree or gnotophoric (having only one contaminant).
Living colonies or species, assembled from pure isolates (separations).
1. An individual organism from a group assembled from pure isolates or separations from other organisms. Also, gnotobiota.
