The determination of electron transfer equilibria A-+ B = A + B-in the gas phase, with a pulsed-electron highpressure mass spectrometer, leads to AGIO, AH,', and ASlo values. These can be converted into the free energy, enthalpy and entropy changes, AGC(B), AH,O(B) and AS,O(B), for the reaction e +

β¦ Synopsis
Oil-polluted freshwater samples collected from Assiut oil company, Egypt, were screened for hydrocarbon-utilizing microorganisms (bacteria and fungi). Two hydrocarbons (naphthalene and anthracene) were used as a sole source of carbon.
Most Probable Number (MPN) technique was used to determine naphthalene and anthraceneutilizing bacteria. Micrococcus, Corynebacteriurn, Nocardia and Pseudonionas were recovered on basal medium supplemented with the hydrocarbons. Numbers of bacteria decreased as the pollution in water increased. Eleven species and 1 variety belonging to 8 terrestrial fungal genera were collected from oil polluted water on naphthalene or anthracene modified CZAPEK agar medium. Aspergillus (A..flauus var. columnaris) and Scopulariopsis ( S . brurnptii) were the most prevalent genera. 75.4 and 24.6% of total bacterial isolates utilized naphthalene and anthracene with different ranges of turbidity, respectively.

artificial lake (control). Three water samples were taken from each stage and from lagoon ( V I ) and artificial (VII) lakes.
Water samples were analysed for the determination of temperature, pH. total dissolved salts, oil content and chemical oxygen demand (American Public Health Association, 1989).
