Effect of Substrate on the Fatty Acid Composition of Hydrocarbon-utilizing Microorganisms1

RESUMO
The fatty acid pattern in three hydrocarbon-utilizing bacteria during growth on various substrates was examined. The predominant fatty acids in acetate-grown cells were C16, C16:1, C18:1, and Br—C19 and the major fatty acids in propane-grown cells were C15, C17, C17:1, C18:1, and Br—C18. When one organism (Mycobacterium sp. strain OFS) was grown on the n-alkanes from C13 to C17, the major fatty acid in the cells was of the same chain length as the substrate. Studies on the incorporation of acetate into the cellular fatty acids of microorganisms growing on C15 and C17n-alkanes suggest that the oxidative products of the substrate are incorporated into the cellular fatty acids without degradation to acetate.
