district of Andhra Pradesh (India) to study the biodiversity of Cyanobacteria from
July 2010-June2011. Cyanobecteria are the most important nitrogen-fixing organisms
because of their autotrophic nutrition and flourish in rice fields and known to sustain
the fertility of this ecosystem. The rice ecosystem allows Cyanobecteria to function
properly, selectively and effectively. Thirty-six species of cyanobecteria recorded.
The present investigation carried out the diversity of nitrogen fixing Cyanobacterial
communities of Guntur rice fields, Andhra Pradesh, India at Tenali mandal site water
and soil samples taken, samples were analysed for taxonomic enumeration. Thirty-six
