title: [Systematic position of an autotrophic actinomycete isolated from a floodplain marsh near Moscow].
abstract: A hydrogen-oxidizing actinomycete (Z-1046) was isolated from a flood-plain marsh in the Moscow Region. Its taxonomy was compared with that of similar cultures belonging to international special standards of actinomycetes (ISP). The strain Z-1046 was found to be identical with Streptomyces autotrophicus ISP-5011 (RIA-1008, ATCC-19727, CBS-466.68, IFO-12743). It has been also shown that the generic identification of the standard culture ISP-5011 is erroneous: as Hirsch (1960) holds, the culture belongs to the genus of Nocardia (Proactinomyces). Thus, the culture Streptomyces (Actinomyces) autotrophicus ISP-5011 must be eliminated from the international special standards of the genera Streptomyces and Streptoverticillium. The autotrophous actinomycete that we have isolated is classed as Proactinomyces autotrophicus comb. nov. (=Streptomyces autotrophicus Takamiya et Tubaki, 1956, ISP-5011, RIA-1008, ATCC-19727, CBS-466.68, IFO-12743, =Nocardia autotrophica, Hirsch, 1960).
