N.A. SORKHOH, R.H. AL‐HASAN, M. KHANAFER AND S.S. RADWAN. 1995. A unique natural microbial cocktail with promising potential for remediating oil‐polluted desert in the Gulf region is reported. Oil‐degrading micro‐organisms immobilized within dense cyanobacterial mats on oily coasts of the Arabian Gulf were successfully established in oil‐contaminated sand. Those micro‐organisms biodegraded 50% of the oil within 10–20 weeks. Nocardioforms belonging to the genus Rhodcoccus predominated in the first few weeks, but after 22 weeks Pseudomonas spp. increased, sharing Rhodococcus in the predominance. Other oil‐utilizing bacterial genera included Bacillus and Arthrobacter. Filamentous actinomycetes belonging to the genera Streptomyces and probably Thermoactinomyces , as well as fungi belonging mainly to Aspergillus and Penicillium increased in the contaminated sand during the experiment but declined later. Representative strains grew on spectra of the tested n ‐alkanes with chain lengths between C 10 and C 40 , as sole sources of carbon and energy.
