Popis:	Five strains belonging to Nocardiaform Actinomycets were isolated from the samples of foaming and scumming activated sludges of a sewage treatment plant in southern part of Miyagi, using modified Bennett medium. Their taxonomical identification was carried out on the basis of the presence of mycolic acid, type of menaquinone and other morphorogical, physiological and genetical examinations. All of the isolated strains had lipolytic activities while none of them had amylolytic and proteolytic activites. They assimilated fatty acids relatively well while they did not assimilate hydrocarbons except octadecane.Most of them were sensitive to tetracycline and chloramphenicol although some of them were resistant to penicillin G and streptomycin. All of them did not have any foaming and sediment retarding effect on the activated sludges when their cultures were added to the normal activated sludges under various laboratory conditions.
