Abstract

Two -like organisms were isolated from water samples obtained in Adelaide, Australia. One organism was isolated from a drinking water distribution system, and the other was isolated from a cooling tower at a sewage treatment plant. Both strains required L-cysteine for growth and contained cellular branched-chain fatty acids and ubiquinones typical of the genus These strains were serologically distinct from each other as determined by a slide agglutination test. Strain 2074-AUS-E (T = type strain) was serologically distinct from all previously described species and serotypes. Strain 2055-AUS-E could not be differentiated biochemically or serologically from Both strains were shown by DNA hybridization studies (hydroxyapatite method) to be members of new species. sp. nov. is the name proposed for strain 2074-AUS-E (= ATCC 51914). was less than 10% related to other species. Strain 2055-AUS-E (= ATCC 51913) was informally named genomospecies 1, since it could not be phenotypically distinguished from genomospecies 1 was closely related to strains (53 to 69% related with 4.5 to 6.5% divergence at 60°C and 31 to 52% related at 75°C).
