GC analysis of crude oil degradation in culture of Pseudomonas sp. ZS1 in presence or absence of Alcaligenes sp. CT10. a GC analysis of hexane extract derived from medium 36 days after shaking without bacteria. A GC spectrum of crude oil in medium is shown. b Linear and branched aliphatic hydrocarbons C₁₇H₃₆ detected. Left panel shows an enlarged image of the Fig. 5a. MS spectra of the linear (upper right penal) and branched (bottom right panel) C₁₇H₃₆ are shown. c A GC spectrum of oils in ZS1 culture at 36 d after growth. An inset shows the branched C₁₇H₃₆ but not linear C₁₇H₃₆ remained noticeable. d A GC spectrum of oils in CT10 culture at 36 days after growth. e A GC spectrum of oils in mixed CT10 and ZS1 culture at 36 days after growth
