FATTY ACID METABOLISM IN SERRATIA MARCESCENS I. : Oxidation of Saturated Fatty Acids by Whole Cells.
Bishop, D. G. (University of Sydney, Sydney, Australia), and J. L. Still. Fatty acid metabolism in Serratia marcescens. J. Bacteriol. 82:370-375. 1961.-A study has been made of the oxidation of saturated fatty acids containing between two and 18 carbon atoms by whole cells of the bacterium, Serratia marcescens. This organism was found to be capable of oxidizing all of the acids tested, but vari...
متن کاملOxidation of unsaturated fatty acids
Plant leaf systems have been incubated under various conditions with uniformly labeled oleic acid, and the breakdown products identified by gas-liquid chromatography. Young green leaves of the castor plant (Ricinis gibsonii) and of the field pea plant (Pisum sutiuum) catabolize oleic acid by an oxygen-requiring pathway to heptadec-8-enaI which is then dehydrogenated by an NAD-coupled mechanism ...
متن کاملMapping the regioisomeric distribution of fatty acids in triacylglycerols by hybrid mass spectrometry.
This study describes the use of hybrid mass spectrometry for the mapping, identification, and semi-quantitation of triacylglycerol regioisomers in fats and oils. The identification was performed based on the accurate mass and fragmentation pattern obtained by data-dependent fragmentation. Quantitation was based on the high-resolution ion chromatograms, and relative proportion of sn-1(3)/sn-2 re...
متن کاملFatty acid oxidation by Penicillium roqueforti.
Although the oxidation of fatty acids by molds has received only superficial study, it has been found that Penicillium roqueforti forms methyl ketones as products of the oxidation. The distinctive taste and odor of bleu cheese is suggestive of 2-heptanone (Hammer and Bryant, 1937), and this compound, together with other methyl ketones, has been isolated from a ripe cheese and identified (Patton...
متن کاملThe oxidation of fatty acids by mycelium of Penicillium roqueforti.
SUMMARY Low concentrations of fatty acids with less than 14 carbon atoms were oxidized without a lag phase over a wide range of pH values by mycelium of Penicillium roqueforti. The effect of the fatty acids upon oxygen uptake by a given weight of mycelium, and the nature of the products of oxidation, were dependent upon the concentration and chain length of the fatty acid and the pH value of th...
