Three strains of non-motile, Gram-positive, filamentous actinomycetes, isolates J4T, J5 and J59, initially recognized microscopically in activated sludge foam by their distinctive branching patterns, were isolated by micromanipulation. The taxonomic... Read More about Gordonia defluvii sp. nov., an actinomycete isolated from activated sludge foam..

Isolates from activated sludge foam were provisionally assigned to the genera Gordona and Tsukamurella on the basis of colony morphology and pigmentation. Representatives of the first group were compared with marker strains of validly described speci... Read More about Activated sludge foaming: The true extent of actinomycete diversity.
