The bioremediation treatment combined a lyophilized bacterial mixture and a nutrient mix containing phosphorus and nitrogen. Samples from the marsh had been collected over a 96-hour period from both treated and untreated oiled sites. Oil fingerprinting fatty acid analysis, polynuclear aromatic hydrocarbons analysis and total petroleum hydrocarbons analysis were performed to evaluate changes in the chemical characteristics of spilled oil. Results of analyses, although not statistically reliable, failed to support the occurrence of any definite chemical alteration in the spilled oil that could be attributed to the bioremediation treatmentanalysisAromatic hydrocarbonsASW,USA,Texas,Galveston BaybiodegradationEnvironmental protectionEvaluationFingerprintingGalveston BayHydrocarbonHydrocarbonsNitrogenO 8050 CONFERENCESOil spillspetroleumPetroleum hydrocarbonsPhosphorusPollution controlPolynuclear aromatic hydrocarbonsQ5 01502 Methods and instrumentsTexasUSACONF
