Mechanisms of membrane toxicity of hydrocarbons.
This review presents general ideas derived from the various reports mentioning toxic effects of lipophilic hydrocarbons on the membrane lipid bilayer, and discusses the effectiveness of changes in membrane lipid composition, modification of outer membrane lipopolysaccharide, altered cell wall constituents, and active excretion systems in reducing the membrane concentrations of lipophile compounds.

Interactions of cyclic hydrocarbons with biological membranes.
The impairment of microbial activity by the cyclic hydrocarbons most likely results from hydrophobic interaction with the membrane, which affects the functioning of the membrane and membrane-embedded proteins. Expand
Metabolism of Styrene Oxide and 2-Phenylethanol in the Styrene-Degrading Xanthobacter Strain 124X
Styrene oxide and 2-phenylethanol metabolism in the styrene-degrading Xanthobacter sp. strain 124X was shown to proceed via phenylacetaldehyde and phenylacetic acid. In cell extracts 2-phenylethanolExpand
Biodegradation of polycyclic aromatic hydrocarbons by new isolates of white rot fungi
Biodegradation of PAH by the various strains was highly correlated to the rate by which they decolorized Poly R-478 dye, demonstrating that ligninolytic indicators are useful in screening for promising PAH-degrading white rot fungal strains. Expand
Identification and Molecular Characterization of an Efflux Pump Involved in Pseudomonas putida S12 Solvent Tolerance*
The deduced amino acid sequences encoded by the three genes involved show a striking resemblance to proteins known to be involved in proton-dependent multidrug efflux systems, opening up the possibilities of using the solvent efflux system to construct bacterial strains capable of performing biocatalytic transformations of insoluble substrates in two-phase aqueous:organic medium.

Aerobic vinyl chloride metabolism in Mycobacterium aurum L1
Three additional bacterial strains which utilize vinyl chloride as a sole carbon and energy source were isolated from environments with no known vinyl chloride contamination, including Mycobacterium aurum L1. Expand
Influence of fructose and glucose on the production of exopolysaccharides and the activities of enzymes involved in the sugar metabolism and the synthesis of sugar nucleotides in Lactobacillus
The absence of activities of enzymes leading to the synthesis of rhamnose nucleotides in fructose-grown cultures appeared to result in the absence of rHAMnose monomer in the exopolysaccharides produced on fructose. Expand
Engineering of Solvent-Tolerant Pseudomonas putida S12 for Bioproduction of Phenol from Glucose
Efficient bioconversion of glucose to phenol via the central metabolite tyrosine was achieved in the solvent-tolerant strain Pseudomonas putida S12, achieving a twofold increase in the overall production compared to a single-phase fed batch. Expand
Growth of the fungus Cladosporium sphaerospermum with toluene as the sole carbon and energy source
The oxygen consumption rates, as well as the measured enzyme activities, of toLUene-grown C. sphaerospermum indicate that toluene is degraded by an initial attack on the methyl group. Expand
Bacteria tolerant to organic solvents
The current knowledge about exceptional strains that can grow in the presence of toxic solvents and the mechanisms responsible for their survival are reviewed. Expand
