A novel pathway producing dimethylsulphide in bacteria is widespread in soil environments.
Nat. Commun. 6 , 6579, (2015) The volatile compound dimethylsulphide (DMS) is important in climate regulation, the sulphur cycle and signalling to higher organisms. Microbial catabolism of the marine osmolyte dimethylsulphoniopropionate (DMSP) is thought to be the major biological process... |

Olfactometry Profiles and Quantitation of Volatile Sulfur Compounds of Swiss Tilsit Cheeses.
J. Agric. Food Chem. 63 , 7511-21, (2015) To establish the odor profiles of three differently fabricated commercial Swiss Tilsit cheeses, analyses were conducted using headspace solid-phase microextraction gas chromatography-mass spectrometry/pulsed flame photometric detection and gas chromatography-... |

Inhaled diesel emissions generated with cerium oxide nanoparticle fuel additive induce adverse pulmonary and systemic effects.
Toxicol. Sci. 142(2) , 403-17, (2014) Diesel exhaust (DE) exposure induces adverse cardiopulmonary effects. Cerium oxide nanoparticles added to diesel fuel (DECe) increases fuel burning efficiency but leads to altered emission characteristics and potentially altered health effects. Here, we evalu... |

Ship-plume sulfur chemistry: ITCT 2K2 case study.
Sci. Total Environ. 450-451 , 178-87, (2013) The ship-plume sulfur chemistry was investigated for the ITCT 2K2 (Intercontinental Transport and Chemical Transformation 2002) ship-plume experiment, using the ship-plume photochemical/dynamic model developed in this study. In order to evaluate the performan... |

Fruit peels support higher yield and superior quality bacterial cellulose production.
Appl. Microbiol. Biotechnol. 99 , 6677-91, (2015) Fruit peels, also known as rinds or skins, are wastes readily available in large quantities. Here, we have used pineapple (PA) and watermelon (WM) peels as substrates in the culture media (containing 5 % sucrose and 0.7 % ammonium sulfate) for production of b... |

Carbonic anhydrase inhibitors. Inhibition studies with anions and sulfonamides of a new cytosolic enzyme from the scleractinian coral Stylophora pistillata.
Bioorg. Med. Chem. Lett. 21 , 710-4, (2011) The catalytic activity and the inhibition of a new coral carbonic anhydrase (CA, EC 4.2.1.1), from the scleractinian coral Stylophora pistillata, STPCA-2, has been investigated. STPCA-2 has high catalytic activity for the physiological reaction being less sen... |

Crosslinked Polypropylenimine Dendrimers With Bioreducible Linkages for Gene Delivery Systems and Their Reductive Degradation Behaviors.
Macromol. Biosci. 15 , 1595-604, (2015) Crosslinked bioreducible polypropylenimine-cystaminebisacrylamides (PPI-CBAs) were synthesized for gene delivery systems. They formed nano-sized polyplexes with high stability even in reducing condition probably due to the re-crosslinking. PPI-CBAs displayed ... |

Nitrogen losses in anoxic marine sediments driven by Thioploca-anammox bacterial consortia.
Nature 500(7461) , 194-8, (2013) Ninety per cent of marine organic matter burial occurs in continental margin sediments, where a substantial fraction of organic carbon escapes oxidation and enters long-term geologic storage within sedimentary rocks. In such environments, microbial metabolism... |

Synthesis and enhanced visible-light responsive of C,N,S-tridoped TiO2 hollow spheres.
J. Environ. Sci. (China) 25(10) , 2150-6, (2013) C,N,S-tridoped TiO2 hollow spheres (labeled as C,N,S-THs) were synthesized using carbon spheres as template and C,N,S-tridoped TiO2 nanoparticles as building blocks. The structure and physicochemical properties of the catalysts were characterized by Xray diff... |
