Cometabolism of methyl tert-butyl ether (MTBE) with alkanes
The release of methyl tert-butyl ether (MTBE) to the environment, mainly from damaged gasoline underground storage tanks or distribution systems spills, has provoked extended groundwater pollution. Biological treatments are, in general, a good alternative for bioremediation of polluted sites; however, MTBE elimination from environment has constituted a challenge because of its chemical structur...
متن کاملInhibition of Growth of a Graphium sp. on Gaseous n-Alkanes by Gaseous n-Alkynes and n-Alkenes.
The growth of a filamentous fungus, a Graphium sp., on n-alkanes (C(inf2) to C(inf4)) was inhibited by low concentrations of acetylene, propyne, 1-butyne, ethylene, and propylene. Acetylene and other unsaturated hydrocarbons had no effect on the growth of the Graphium sp. on potato dextrose broth, ethanol, or acetate. Our results suggest that n-alkynes and n-alkenes are selective inhibitors of ...
متن کاملMicrobial Oxidation of Gaseous Hydrocarbons: Production of Methylketones from Corresponding n-Alkanes by Methane-Utilizing Bacteria.
Cell suspensions of methane-utilizing bacteria grown on methane oxidized n-alkanes (propane, butane, pentane, hexane) to their corresponding methylketones (acetone, 2-butanone, 2-pentanone, 2-hexanone). The product methylketones accumulated extracellularly. The rate of production of methylketones varied with the organism used for oxidation; however, the average rate of acetone, 2-butanone, 2-pe...
متن کاملInduction of toluene oxidation activity in Pseudomonas mendocina KR1 and Pseudomonas sp. strain ENVPC5 by chlorinated solvents and alkanes.
Toluene oxidation activity in Pseudomonas mendocina KR1 and Pseudomonas sp. strain ENVPC5 was induced by trichloroethylene (TCE), and induction was followed by the degradation of TCE. Higher levels of toluene oxidation activity were achieved in the presence of a supplemental growth substrate such as glutamate, with levels of activity of up to 86% of that observed with toluene-induced cells. Act...
متن کاملChemical and physical characterization of four interfacial-active rhamnolipids from Pseudomonas spec. DSM 2874 grown on n-alkanes.
Four extracellular glycolipids produced under growth-limiting conditions were isolated from the culture broth of Pseudomonas spec. DSM 2874. After purification by column and thick-layer chromatography they were identified as anionic rhamnolipids. 1H and 13C-NMR studies showed that two of these, beta(beta(2-O-alpha-L-rhamnopyranosyloxy)decanoyl)decanoic acid and beta(beta(2-O-alpha-L-rhamnopyran...
