The effect of petroleum hydrocarbons on survival and pigments of cyanobacteria isolated from Abadan

Remediation of petroleum polluted soil and water is very important. One of the pathways of oil remediation is usage of microalgae and cyanobacteria. In this research the effects of oiled based drilling mud waste (including 70% gasoline) on survival, growth and pigments of three cyanobacteria (Oscillatoria+Calothrix, Nostoc, Calothrix) in mix and unialgal forms were investigated. These cyanobacteria were isolated from soil of Arvand-rood in Abadan city. Results indicated that biomass of first sample was three fold of other samples. Growth rate in first sample was increasingly. In second and third samples, growths were decreased and reach to stationary phase after one week. All samples survived in treated experiments and oil compound did not have any toxic effects of them. Chlorophyll contents were similar to biomass and in first sample were three fold of others. Totally, results showed the resistance and potential of these species to degradation of oil pollution. Also these results are the first report from oil polluted fields of Iran.
