Paraffin oxidation in Pseudomonas aeruginosa. I. Induction of paraffin oxidation.
The induction of paraffin oxidation in intact cells of Pseudomonas aeruginosa was investigated. Oxidation of (14)C-heptane by cell-free extracts of adapted cells showed that the activity of whole cells is a reliable reflection of the synthesis of the first enzyme in the degradation of n-alkanes. Induction was significantly affected by glucose and could be completely repressed by malate. The ami...
متن کاملRHAMNOLIPIDS PRODUCED BY PSEUDOMONAS AERUGINOSA GROWN ON ^-PARAFFIN (MIXTURE OF C12, ds AND Cu FRACTIONS)
Two kinds of glycolipids (R-l and R-2) were produced in the culture media by several strains of Pseudomonas aeruginosa when grown on nparaffin (mixture of C12, C13. and Cu fractions). These compounds were isolated through the extraction of the culture broth with ethylacetate and the chromatography on silicic acid column. On the basis of chemical analysis, these lipids were characterized as 2-O-...
متن کاملThe Effect of Aromatic Hydrocarbons on the Oxidation Stability of Squalane (Part 1)* -Oxidation of Squalane as a Model Compound of Paraffin Portion in Mineral Oil-
Di-tert-butyl peroxide (DTBP) and 2, 2'-azobisisobutyronitrile (AIBN) were used as initiators and chlorobenzene was used as an inert solvent. The values of kp/(2kt)1/2 in the neat phase are slightly less than those in chlorobenzene solution for a given initiator concentration and temperature. This retardation can be attributed to the solvent effect of chlorobenzene on the decomposition rate of ...
متن کاملCarbohydrate Oxidation by Pseudomonas Fluorescens
Glucose oxidation by Pseudomonas Jluorescens (1) and Pseudomonas aeruginosa (2) has been shown to proceed via gluconate to 2-ketogluconate without the involvement of phosphorylated intermediates. 2-Ketogluconate is oxidized further in growing cultures (3) and resting cell suspensions (4), but attempts to obtain dried cell preparations or cell-free extracts which oxidize 2-ketogluconate have bee...
متن کاملCarbohydrate Oxidation by Pseudomonas Ruorescens
Glucose utilization by extracts of Pseudomonas jhwrescens involves its oxidation to gluconate and 2-ketogluconate (1, 2) by cytochrome-linked dehydrogenases (1). 2-Ketogluconate is phosphorylated by an inducible kinase, which is distinct from gluconokinase, and 2-keto-6-phosphogluconate, the phosphorylation product, has been isolated and identified (3). The conversion of 2-keto-6-phosphoglucona...
