    Seasonal biodiversity of cyanobacteria in besmirched habitats

    ABSTRACT
    Cyanobacteria inhabit a diverse range of ecosystems, a number of features often contribute to their success. Growth of these organisms in many ecosystems is limited by the availability of nutrients. High load of solids, carbon and nutrients indicate proliferation of cyanobacteria, while low nutrient condition diminishes cyanobacterial growth. This study examines cyanobacterial diversity in domestic and hospital sewage of Sagar, Madhya Pradesh (M.P), India, from January 2013 to December 2013. Cyanobacterial biodiversity was higher during study period and dominated by Aphanocapsa, Chroococcus, Phormidium and Nostoc species. The present investigation exhibits a baseline of information on cyanobacterial diversity associated with wastewater under the influence of urbanization. Massive urbanizations in developing countries have polluted fresh water bodies and terrestrial areas nearby. This information can be utilized to identify cyanobacterial species for bioremediation of sewage. There are a number of Cyanophyceae members which are tolerant to organic pollution and resist environmental stress by pollutants. These species may be further used as pollution indicators for such habitats. Cyanobacterial species can constrain future pollution and can play a key role to accomplish the dream of pollution-free environment.
