| identification of fatty acids and aliphatic hydrocarbons in sarcina lutea by gas chromatography and combined gas chromatography-mass spectrometry. | the composition and nature of the fatty acids and hydrocarbons of sarcina lutea were elucidated by gas chromatography and by combined gas chromatography-mass spectrometry. the distribution of fatty acids found in s. lutea showed two families of pairs, or dyads, of saturated monocarboxylic acids (c12-c18) with and without methyl branching. these pairs of fatty acids showed a pattern of iso and anteiso structures for c13, c15, and c17, and iso and normal structures for c12, c14, and c16. only the ... | 1967 | 6039356 |
| fatty acid and aliphatic hydrocarbon composition of sarcina lutea grown in three different media. | sarcina lutea was grown in trypticase soy broth, nutrient broth, and a chemically defined medium. gas chromatographic analysis of lipid components demonstrated that the composition of the medium had an effect on the relative per cent composition of the aliphatic hydrocarbons and fatty acids present in the cells. the branched olefinic hydrocarbons from the organisms grown in trypticase soy broth showed no predominance or only a slight predominance of odd-numbered carbon chains, whereas the hydroc ... | 1967 | 6039357 |
| 14-c incorporation into the fatty acids and aliphatic hydrocarbons of sarcina lutea. | an initial investigation into the mechanism of hydrocarbon biosynthesis in sarcina lutea was performed by measuring the amounts of (14)c incorporated into the hydrocarbons and fatty acids by use of a combination gas chromatograph and high-temperature gas-flow ionization apparatus. uniformly labeled l-isoleucine-(14)c was predominantly incorporated into the anteiso-branched chains. palmitate-16-(14)c gave evidence that a direct correlation may exist between the nonpolar end of the palmitate and t ... | 1967 | 6039358 |

| ribosyl and deoxyribosyl transfer by bacterial enzyme systems. | the enzymatic transfer of ribose and deoxyribose residues in pyrimidine nucleosides to purines was catalyzed by cell-free extracts of various bacteria. almost all the strains belonging to enterobacteriaceae were capable of catalyzing the transfer reactions. the transfer activities were also detected among some bacterial strains of other families: pseudomonadaceae, corynebacteriaceae, micrococcaceae, bacteriaceae, and bacillaceae. the rates of the transfer reactions were greatly enhanced in the p ... | 1967 | 4863982 |
| conversion of ddt to ddd by pathogenic and saprophytic bacteria associated with plants. | of 27 microorganisms examined, 23 plant pathogenic and saprophytic bacterial species were found to convert p,p' ddt to p,p' ddd under anaerobic conditions. the range of conversion of ddt (10 micrograms per milliliter) during an incubation of 14 days was from a trace to over 5 micrograms per milliliter, with the majority of the bacteria showing the greatest activity during the final 7-day period. there is evidence that metabolites of ddt other than ddd are also produced. | 1967 | 4961613 |
