The significant features of the chemical changes that were observed included a marked decrease in the proportion of n-alkanes relative to isoprenoid hydrocarbons, the transient occurrence of an increase in unresolved hydrocarbons within the first year following the AMOCO CADIZ spillage, and the decreased importance of unsubstituted polynuclear aromatic hydrocarbons relative to dibenzothiophenes and the comparable or substituted forms of the polynuclear aromatic hydrocarbons (Figs. 2 and 3). The In vitro hydrocarbon biodegradation experiments confirmed the fact that the indigenous microbial populations were capable of rapid and extensive degradation of Arabian crude oil. Much greater rates of biodegradation were observed in agitated compared to flow through experiments (Figs. 4-9). Both the in vitro experiments and the analysis of field experiments support the hypothesis that mixing energy has a very significant effect on the rates of hydrocarbon biodegradation. Rates of biodegradation appear to be environmentally influenced by the turbulence of mixing which can ensure a continued supply of nutrients and oxygen as well as dispersing the oil so as to establish a favorable surface area to volume ratio for rapid microbial hydrocarbon biodegradation. The similarity of changes, observed in the composition of the hydrocarbon mixture i_n vitro compared to the analysis of field samples also suggests that nutrients were not a limiting factor that determined the rates of hydrocarbon biodegradation. The analysis of the polar fractions from the iri vitro experiments showed some surprising results (Table 21). There was a lack of oxygenated aromatic compounds. It had been predicted that there would be a greater accumulation of polar products from aromatic biodegradation since less CO was being produced than from aliphatic biodegradation where a significant proportion of the hydrocarbon that was biodegraded was released as CO . There were significant accumulations of polar compounds that appear to be biodegradation products of aliphatic hydrocarbons, especially as C.,-C „ acids. Interestingly, the major polar products included unsaturated acids. As a rule, the predominant biochemical pathway for the biodegradation of straight chained hydrocarbons does not involve the formation of unsaturated compounds, although a biochemical pathway has recently been elucidated for some bacteria that does introduce a double bond into the hydrocarbon. It appears that the microbial populations indigenous to the sediment of the Brittany Coast possess such a biochemical capability. 18
