Subterminal oxidation of aliphatic hydrocarbons.
Evidence is presented for a catabolic pathway of n-alkane oxidation which proceeds via subterminal oxidation rather than methyl group oxidation.
متن کاملCapillary Electrochromatography: Polycyclic Aromatic Hydrocarbons
Electrochromatography is utilized to separate a mixture of 16 different polycyclic aromatic hydrocarbons (PAHs). Fused-silica capillary columns ranging in size from 50 to 150 pm i.d. were packed (20-40-cm sections) with 3-pm octadecylsilica particles. A potential of 15-30 kV is applied across the 30-50-cm total length capillary column to generate electroosmotic flow that carries the PAHs throug...
متن کاملAliphatic hydrocarbons of Cladosporium resinae cultured on glucose, glutamic acid, and hydrocarbons.
The carbon source markedly influenced the qualitative and quantitative composition of cellular hydrocarbons in Cladosporium resinae. Total lipid and hydrocarbon content was greater in cells grown on n-alkanes than in cells grown on glucose or glutamic acid. Glucose-grown cells contained a spectrum of aliphatic hydrocarbons from C(7) to C(36); pristane and n-hexadecane comprised 98% of the total...
متن کاملDegradation of unsaturated hydrocarbons by methanogenic enrichment cultures
The biodegradability of hydrocarbons under anaerobic conditions was studied in enrichment cultures using mineral media inoculated with sewage sludge or sediment samples of limnic and marine origin. No indication of methanogenic degradation was obtained with either n-hexane, nhexadecane, n-heptadecane, 1-hexene, cis-2hexene, trans-2-hexene, isoprene, 1-hexine, benzene, toluene, xylene, cyclohexe...
متن کاملThe Toxicity and Potential Dangers of Aliphatic and Aromatic Hydrocarbons *
The aliphatic hydrocarbons play an increasing role as solvents in different industries and the appraisal of the hazards connected with their use offers considerable difficulties because most of these solvents represent mixtures, sometimes of heterogeneous nature, and because their composition is frequently only incompletely known. In order to evaluate the potential dangers of such mixtures it i...
