Cyanospira rippkae and Cyanospira capsulata (gen. nov. and spp. nov.): new filamentous heterocystous cyanobacteria from Magadi lake (Kenya)

Piazzale delle Cascine, 27 I-50144 Firenze Italia Abstract New filamentous heterocystous cyanobacteria were isolated from the alkaline soda lake Magadi in Kenya. The characteristics of the isolates are summarized and their taxonomic position discussed. Uniform attributes of the strains, grouped in two types, Mag II 702 and Mag I 504 are the following: helical structure of the trichomes, immotility, gas vacuolation, obligate autotrophy, nitrogen fixation under aerobic conditions, and closely similar fatty acid composition, including the uncommon cis-vaccenic acid. For these organisms the assignment to a new genus named Cyanospira is proposed with the species C. rippkae and C. capsulata , separated on the basis of structural, chemical and mean DNA-base composition. Type strains 702 and 504 will be deposited at the ATCC and PCC. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Microbiology Springer Journals
