Abstract

India has great biodiversity of blue green algae in general which has contributed to fertility of the soils and in relatively well documented. Efforts have been made to study the algal flora in the tailings or cyanide dumps of the Kolar gold fields and an attempt has been made to draw the knowledge about heterocyst and non-heterocyst nitrogen fixing organisms like blue green algae, which are ubiquitous in distribution and contribute to the world wide nitrogen status. It has been widely studied in the paddy field soils addition of Cyanobacteria to enhance the crop yield. Algalisation is best where nearby species are utilized to get ready inoculums. It is therefore important to have detailed information of indigenous algal population particularly the nitrogen fixating species. Several investigative reports on the abundance of soil algae in different geographical areas of India are available. Many areas of region still remain unexplored. In this context the present investigation was taken up in the tailings or cyanide dumps and recorded 60 algal species in which, 37 species of Cyanophyceae, 12 species of Chlorophyceae, 09 species of Bacillariophyceae amd 2 species of Euglenophyceae. The most abundance genera of algae present in the area are as follows Microcystis elongata, Anabaena circinalis, Aphanocapsa koordaesi, Calothrix castelli, Chroococcus giganteus, Gloeocapsa gelatinosa, Crinalium magnum, Nostoc commune, Oscillatoria obscura, Phormidium parpurescens, Synechococcus pevalikii, Chlorella vulgaris, Chlorococcum croccum, Cymbella ventucosa, Navicula rhomboids, Euglena elongata etc.
