Ecological Study of Algae from Oil Industry Waste Water

Oil industry waste water is one of the important source of water pollution. It is rich in organic contents and shows eutrophic condition. It is contains oil, oil products and other organic contents which is responsible for pollution of water and affects aquatic flora and fauna. In such environment there are certain algae which grows and found in diverse form. Oil industry waste water is used as source of nutrients by algae. During present research work algal diversity and physico-chemical assessment of oil industry waste water has been studied in detail. Experimental work was carried out for two consecutive years i.e. from June 2015 to May 2017. Algal samples were collected at monthly intervals from waste water of Mahesh oil industry, located in Selu tahsil area of Parbhani district of Maharashtra. Physico-chemical assessment of oil industry waste water was also performed by selecting certain physico-chemical parameters. Total of 40 species under 27 genera belonged to Chlorophyceae, Bacillariophyceae, Euglenophyceae and Cyanophyceae were recorded. Cyanophycean algal taxa dominated algal flora. Algal genera such as  Gloeocystis, Trebouxia, Chlorella, Navicula, Cymbella, Nitzschia, Euglena, Aphanothece, Oscillatoria,  Phormidium and Plectonema dominated algal flora. It was observed that winter and summer seasons were sutiable for abundance of algae. There is positive correlation between physico-chemical parameters of water and algal flora.
