TLDR
Branched-chain fatty acids of the iso and anteiso series occur in many bacteria as the major acyl constituents of membrane lipids and are an important criterion used to aid identification and classification of bacteria.About:

Bacterial volatiles: the smell of small organisms
TL;DR: This review describes volatiles released into the air by bacteria growing on defined media and an effort has been made to organize the compounds according to their biosynthetic origin.

TL;DR: Comparative analysis of the 16S rDNA sequences and fatty acid compositions of the novel isolates and established species of thermophilic bacilli indicated that the subsurface strains represent two new species within a new genus, for which the names Geobacillus subterraneus gen. nov., sp.nov.

Comparative organic geochemistries of soils and marine sediments
John I. Hedges,J.M Oades +1 more
TL;DR: In the ocean, nitrogen-rich microorganisms produce and recycle most organic matter in the water column, from which degraded particles rain onto the underlying sea floor and the buried organic matter joins the geological cycle, surfacing again millions of years later as kerogen uplifted in continental rocks as discussed by the authors.

Comparative Analysis of Methane-Oxidizing Archaea and Sulfate-Reducing Bacteria in Anoxic Marine Sediments
Victoria J. Orphan,Kai-Uwe Hinrichs,William Ussler,Charles K. Paull,Lance T. Taylor,Sean P. Sylva,John M. Hayes,Edward F. DeLong +7 more
TL;DR: Results of rRNA gene surveys and lipid analyses of archaea and bacteria associated with methane seep sediments from several different sites on the Californian continental margin suggest that other bacteria and archaea are also involved in methane oxidation in these environments.

The relationship between environmental temperature, cell growth and the fluidity and physical state of the membrane lipids in Bacillus stearothermophilus
TL;DR: Evidence is presented here that the electron spin resonance techniques used previously did not in fact detect the gel to liquid-crystalline phase transition of the bulk membrane lipids, which, however, can be reliably measured by differential thermal analysis.

Mycobacterium phlei Fatty Acid Synthetase-A Bacterial Multienzyme Complex
TL;DR: Unlike other bacteria, Mycobacterium phlei elaborates a fatty acid synthetase of high molecular weight that requires a heat-stable factor and is inactivated in solutions of low ionic strength.

TL;DR: Out of a series of tested analogues, 2-methylvalerate,2-ethyl butyrate, and trimethylacetate were found to be active in vivo as primer molecules of branched chain fatty acid biosynthesis.

Cellular fatty acid composition in gram-negative obligately anaerobic rods
TL;DR: The cellular fatty acid composition of 27 strains of gram-negative obligately anaerobic rods was determined by gas-liquid chromatography and this analysis appeared to be an aid in the grouping of the bacteria.

Omega-cyclohexyl fatty acids in acidophilic thermophilic bacteria. Studies on their presence, structure, and biosynthesis using precursors labeled with stable isotopes and radioisotopes.
TL;DR: Findings indicate that omega-cyclo hexyl fatty acids are synthesized with glucose through shikimic acid and probably cyclohexyl carboxylyl-CoA derivative as the intermediates.
