Construction and Comparison of Trametes versicolor Laccase Biosensors Capable of Detecting Xenobiotics
(Informa Healthcare, 2010)Amperometric biosensors using laccase from Trametes versicolor as a bioelement were developed for 2,4-dichloro phenoxy acetic acid (2,4-D). Laccase enzyme was immobilized by gelatin and glutaraldehyde onto a Clark oxygen ... -
9-(4-Nitrophenylsulfonyl)-9H-carbazole
(Wiley-Blackwell, 2011)In the title molecule, C18H12N2O4S, the carbazole skeleton is nearly planar [maximum deviation = 0.037 (1) A] and is oriented at a dihedral angle of 73.73 (5)degrees with respect to the benzene ring. An intramolecular ... -
Biodiesel production from waste frying oils and its quality control
(Pergamon-Elsevier Science Ltd, 2010)The use of biodiesel as fuel from alternative sources has increased considerably over recent years, affording numerous environmental benefits. Biodiesel an alternative fuel for diesel engines is produced from renewable ... -
5-(3,6-Dibromo-9H-carbazol-9-yl)pentanenitrile
(Wiley-Blackwell, 2011)In the title compound, C17H14Br2N2, the carbazole skeleton is nearly planar [maximum deviation = 0.055 (2) angstrom]. In the crystal, aromatic pi-pi stacking is observed between parallel carbazole ring systems of adjacent ... -
Trifolium L. - A Review on its Phytochemical and Pharmacological Profile
(Wiley, 2009)Plants from the genus Trifolium have been used in traditional medicine by many cultures. In Turkish folk medicine, for example, some Trifolium species are used for their expectorant, analgesic, antiseptic properties and ... -
