Limnological characteristics of the freshwater ecosystems of Byers Peninsula, Livingston Island, in maritime Antarctica
A limnological survey of 15 lakes and 6 streams was carried out on Byers Peninsula (Livingston Island, South Shetland Islands, Antarctica) during austral summer 2001–2002. Most of the surface watersExpand

Acclimation of photosynthetic pigments and photosynthesis of the cyanobacterium Nostoc sp. strain UAM206 to combined fluctuations of irradiance, pH, and inorganic carbon availability
Summary We analysed the combined effect of pH, irradiance, and inorganic carbon availability on growth and pigment composition of the cyanobacterium Nostoc sp. strain UAM206, isolated from riceExpand

mrpA, a gene with roles in resistance to Na+ and adaptation to alkaline pH in the cyanobacterium Anabaena sp. PCC7120.
Transposon mutagenesis of Anabaena sp. PCC7120 led to the isolation of a mutant strain, PHB11, which grew poorly at pH values above 10. The mutant strain exhibited pronounced Na+ sensitivity; thisExpand

Microstructural Characterization of Cyanobacterial Mats from the McMurdo Ice Shelf, Antarctica
ABSTRACT The three-dimensional structures of two types of cyanobacterium-dominated microbial mats from meltwater ponds on the McMurdo Ice Shelf were as determined by using a broad suite ofExpand

Essentiality of Boron for Dinitrogen Fixation in Anabaena sp. PCC 7119.
The relationship between the requirement for boron and the form of N supplied in nutrient media to cyanobacterium Anabaena sp. PCC 7119 was investigated. When cells were grown in a medium whichExpand

Wide variation in the cyanobacterial complement of presumptive penicillin-binding proteins
A genomic analysis of putative penicillin-binding proteins (PBPs) that are involved in the synthesis of the peptidoglycan layer of the cell wall and are encoded in 12 cyanobacterial genomes wasExpand
