Abstract
Chlorophyll b-containing, phycobiliprotein-less cyanobacterium ("prochlorophyte") Prochlorothrix scandica Skulberg 2008 represents the second species of the genus Prochlorothrix. Distinction between the strains P. scandica NIVA-8/90 and Prochlorothrix hollandica PCC 9006 (CCAP 1490/1T) is based predominantly on genomic DNA properties. The degree of DNA reassociation of the two strains is 5 %. Compared to P. hollandica, P. scandica possesses an additional rrn operon. In addition, there is a distinct polymorphism of the highly iterated short palindromes (Hip1). Among the phenotypic features different in the two species are cell morphology, growth temperature optimum and fatty acids content.
