Abstract
Isolate PCM 2404T (T = type strain) from the Polish Collection of Microorganisms is proposed as the type strain of a new species, Streptomyces spitsbergensis. This new species is characterized by a nonfragmenting vegetative mycelium, rectiflexibiles spore chains, a type I cell wall, type PII phospholipids, a lack of mycolic acids and major glycolipids, and a G+C content of 71 mol%. A comparison with related species of the genus confirmed the validity of the proposed taxon.
