TLDR
Fatty acids derived from Micrococcus cerificans growing at the expense of odd- and even-carbon normal alkanes demonstrated that cultures grown with a variety of nonhydrocarbon substrates serving as sole carbon and energy source yielded only even- carbon fatty acids.Abstract:
Fatty acids derived from Micrococcus cerificans growing at the expense of odd- and even-carbon normal alkanes were studied. Results demonstrated that cultures grown with a variety of nonhydrocarbon substrates serving as sole carbon and energy source yielded only even-carbon fatty acids. Even-chain alkanes, dodecane through octadecane serving as sole carbon source, resulted in even-carbon fatty acids with direct correlation between carbon number of the major fatty acid species and carbon number of the alkane substrate. Odd-carbon alkanes, undecane through heptadecane serving as sole carbon source, yielded both odd- and even-carbon fatty acids. A transitional shift from even-carbon fatty acids to odd-carbon fatty acids was observed as the carbon number of the alkane substrate increased. Unsaturated fatty acids were found to comprise a significant percentage of all profiles. Analysis of unsaturated fatty acids showed all odd- and even-carbon acids analyzed were Δ9 monounsaturated fatty acids.read more

Effects of migration of soil lipids on organic residues associated with buried potsherds
TL;DR: In this paper, the effects of post-depositional intrusion of soil organic matter on organic residues retained in the porous walls of pottery vessels has been largely overlooked, and the results show that in the majority of cases clear qualitative and quantitative distinctions can be drawn between the lipid constituents of the soil, arising from the decay of higher plants and micro-organisms, and those absorbed in the sherd during its period of use.

TL;DR: Studies on the incorporation of acetate into the cellular fatty acids of microorganisms growing on C(15) and C(17)n-alkanes suggest that the oxidative products of the substrate are incorporated into the Cellular fatty acids without degradation to acetate.
