Cyanobacteria are distributed worldwide, and many new cyanobacterial species discovered in tropical region. TheNostoc-like genus Amazonocrinis has been separated from the Nostoc based on polyphasic methods. However,species diversity within this remains poorly understood systematically because only one (Amazonocrinisnigriterrae) described. In study, two novel strains (NUACC02 NUACC03) were isola...

The vegetative cells of the filamentous cyanobacterium Nostoc punctiforme can differentiate into three mutually exclusive cell types: nitrogen-fixing heterocysts, spore-like akinetes, and motile hormogomium filaments. A DNA microarray consisting of 6,893 N. punctiforme genes was used to identify the global transcription patterns at single time points in the three developmental states, compared ...

Taking into account the high potential of cyanobacteria to tolerate salinity stress, researches have evaluated the morphological and physiological behavior of these microorganisms in recent years. This study is conducted to investigate the impact of different concentrations of NaCl on the morphological and physiological traits of Nostoc sp. ISC 101. Biometrical and morphological observations ar...
