Certain commercially interesting taxa of phormidioideae, phormidiaceae (oscillatoriales cyanoprokaryote) from polluted sites of meerut, uttar pradesh, india

The present paper deals with the diversity of non-heterocystous filamentous blue-green algal taxa of the family Phormidiaceae, Oscillatoriales, Cyanoprokaryote. Blue-green algal samples were collected from three different polluted water reservoirs of Meerut, U.P., India and identified upto the species level. The present study revealed the occurrence of total 15 strains of 08 species of 4 genera of subfamily Phormidioideae of the family Phormidiaceae, Oscillatoriales, Cyanoprokaryote viz. Arthrospira khannae, A. maxima, Planktothrix agardhii, P. clathrata, P. isothrix, Planktothricoides raciborskii, Tychonema bornetii and T. sequanum. The study also revealed the occurrence of potential strains of non-heterocystous filamentous blue green algae from three polluted water reservoirs of Meerut, U.P., India. Three taxa Planktothricoides raciborskii, Tychonema bornetii and T. sequanum are being reported first time from India.
