Table 7 indicates GCMS analysis of extracellular hydrocarbon biotransformation of spent rolling emulsions by S. vacuolatus. Intermediates and metabolites were also observed and indicative of the biotransformations. After week 1, twenty-four chemical compounds were present compared to the control. A significant reduction and increase in hydrocarbon concentration were observed. Tetradecane was most abundant while tetradecane 5-methyl was least abundant in the oil. New compounds such as dodecane, undecane,2,6-dimethyl, acetic acid 3,7,11,15-tetramethyl-hexadecyl ester, cyclohexane,(4-methylpentyl)-, 1-decanol,2-octyl-, dodecane,4-methyl-, decane,2,3,6-trimethyl-, dodecane,4,6-dimethyl-, 2-hexadecene,3,7,11,15-tetramethyl, oxalic acid, cyclohexyl methyl tridecyl ester, 1,1′-bicyclohexyl,2-methyl,trans, oxalic acid,2-ethylhexyl tetradecyl ester, nonahexacontanoic acid, hexadecane,2,6,11,15-tetramethyl and tridecane,4-cyclohexyl were formed. Dodecane,4-methyl, undecane,2,6-dimethyl and decane,2,3,6-trimethyl were found to be isomers of tridecane while dodecane,4,6-dimethyl isomer of tetradecane.
