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

K R Dunlap a, J J Perry a
PMCID: PMC252300  PMID: 16562157

Abstract

The fatty acid pattern in hydrocarbon- and ketone-utilizing bacteria after growth on various substrates was examined. The fatty acid composition of one hydrocarbon-utilizing organism (Mycobacterium sp. strain OFS) was investigated in detail after growth on n-alkanes, 1-alkenes, ketones, and n-alcohols. n-Alkanes shorter than C13 or longer than C17 were not incorporated into cellular fatty acids without some degradation. Strain OFS incorporated C14 to C17 1-alkenes into cellular fatty acids as the ω-monoenoic fatty acid. Methyl ketones were incorporated into strain OFS after removal of one- or two-carbon fragments from the carbonyl end of the molecule. An organism isolated by enrichment on methyl ketones was incapable of n-alkane utilization but could grow on, although not incorporate, ketones or long chain n-alcohols into cellular fatty acids.
