Paralogous chemoreceptors mediate chemotaxis towards protein amino acids and the non‐protein amino acid gamma‐aminobutyrate (GABA)
08-05-2013 | Miriam Rico‐Jiménez, Francisco Muñoz‐Martínez, Cristina García‐Fontana, Matilde Fernandez, Bertrand Morel, Álvaro Or ..., Molecular Microbiology, 2013
Summary The paralogous receptors PctA, PctB and PctC of Pseudomonas aeruginosa were reported to mediate chemotaxis to amino acids, intermediates of amino acid metabolism and chlorinated hydrocarbons. We show that the recombinant ligand binding regions (LBRs) of PctA, PctB and PctC bind ...
Identification and characterization of 2‐naphthoyl‐coenzyme A reductase, the prototype of a novel class of dearomatizing reductases
07-05-2013 | Christian Eberlein, Sebastian Estelmann, Jana Seifert, Martin von Bergen, Michael Müller, Rainer U. Meckenstock, Mat ..., Molecular Microbiology, 2013
Summary The enzymatic dearomatization of aromatic ring systems by reduction represents a highly challenging redox reaction in biology and plays a key role in the degradation of aromatic compounds under anoxic conditions. In anaerobic bacteria, most monocyclic aromatic growth substrates ...
Synthesis of customized petroleum-replica fuel molecules by targeted modification of free fatty acid pools in Escherichia coli [Applied Biological Sciences]
07-05-2013 | Thomas P. Howard; Sabine Middelhaufe; Karen Moore; Christoph Edner; Dagmara M. Kolak; George N. Taylor; David A. Par ..., Proceedings of the National Academy of Sciences current issue, 2013
Biofuels are the most immediate, practical solution for mitigating dependence on fossil hydrocarbons, but current biofuels (alcohols and biodiesels) require significant downstream processing and are not fully compatible with modern, mass-market internal combustion engines. Rather, the ideal ...
Malondialdehyde–deoxyguanosine and bulky DNA adducts in schoolchildren resident in the proximity of the Sarroch industrial estate on Sardinia Island, Italy
01-05-2013 | Marco Peluso; Armelle Munnia; Marcello Ceppi; Roger W. Giese; Dolores Catelan; Franca Rusconi; Roger W. L. Godschalk ..., Mutagenesis, 2013
Air quality is a primary environmental concern in highly industrialised areas, with potential health effects in children residing nearby. The Sarroch industrial estate in Cagliari province, Sardinia Island, Italy, hosts the world’s largest power plant and the second largest European oil ...
The effect of natural and liquid smokes on the benzo‐α pyrene content and quality parameters of Circassian cheese
19-04-2013 | Pinar Aydinol, Tulay Ozcan, International Journal of Dairy Technology, 2013
The objective of this study was to determine the effects of natural smoke and liquid smoke application methods on quality characteristics of smoked Circassian cheese. The microbial counts of liquid smoked cheeses were found to be higher than naturally smoked cheeses. It can be concluded ...
Differential Action of Monohydroxylated Polycyclic Aromatic Hydrocarbons with Estrogen Receptors {alpha} and {beta}
01-04-2013 | Chelsie K. Sievers; Erin K. Shanle; Christopher A. Bradfield; Wei Xu, Toxicological Sciences, 2013
Polycyclic aromatic hydrocarbons (PAHs) are a diverse group of widespread environmental pollutants, some of which have been found to be estrogenic or antiestrogenic. Recent data have shown that hydroxylated PAH metabolites may be responsible for the estrogenic effects of some PAHs. The ...
Mice exposed in situ to urban air pollution exhibit pulmonary alterations in gene expression in the lipid droplet synthesis pathways
27-03-2013 | Andrea Rowan‐Carroll, Sabina Halappanavar, Andrew Williams, Christophers M. Somers, Carole L. Yauk, Environmental and Molecular Mutagenesis, 2013
It is clear that particulate air pollution poses a serious risk to human health; however, the underlying mechanisms are not completely understood. We investigated pulmonary transcriptional responses in mice following in‐situ exposure to ambient air in a heavily industrialized urban ...
Effects of petroleum mixture types on soil bacterial population dynamics associated with the biodegradation of hydrocarbons in soil environments
12-03-2013 | Natsuko Hamamura, David M. Ward, William P. Inskeep, FEMS Microbiology Ecology, 2013
Abstract Soil bacterial population dynamics were examined to assess patterns in microbial response to contamination by different petroleum mixtures with variation in n‐alkane profiles or toxic constituents such as pentachlorophenol (PCP). Three soil types from distinct areas of the United ...
Biodegradation of petroleum hydrocarbons in the presence of nickel and cobalt
01-03-2013 | Ganiyu Oladunjoye Oyetibo, Matthew Olusoji Ilori, Oluwafemi Sunday Obayori, Olukayode Oladipo Amund, Journal of Basic Microbiology, 2013
Abstract Bioremediation of environments co‐contaminated with hydrocarbons and heavy metals often pose a challenge as heavy metals exert toxicity to existing communities of hydrocarbon degraders. Multi‐resistant bacterial strains were studied for ability to degrade hydrocarbons in ...
Genetic polymorphisms in catalase and CYP1B1 determine DNA adduct formation by benzo(a)pyrene ex vivo
01-03-2013 | Marten A. Schults; Roland K. Chiu; Peter W. Nagle; Lonneke C. Wilms; Jos C. Kleinjans; Frederik J. van Schooten; Rog ..., Mutagenesis, 2013
Genetic polymorphisms can partially explain the large inter-individual variation in DNA adduct levels following exposure to polycyclic aromatic hydrocarbons. Effects of genetic polymorphisms on DNA adduct formation are difficult to assess in human studies because exposure misclassification ...
