Five cyanobacterial species ( Phormidium sp., Nostoc sp., Anabaena sp. Aphanothece conferta, and Synechocystis aquatilis ) isolated from the Suez Canal coast at the city of Ismailia (Egypt) were tested for biodegradation of four hydrocarbon (HC) compounds: two aliphatic compounds ( n ‐octadecane and pristine) and two aromatic compounds (phenanthrene and dibenzothiophene). High degradation efficiencies for the two aliphatic compounds were measured for A. conferta (64% for n ‐octadecane and 78% for pristine) and S. aquatilis (85% for n ‐octadecane and 90% for pristane). However, the other biodegradation percentages ranged between weak and moderate percentages.
