Isolation, identification, and biochemical characterization of a brown rot fungus capable of textile dye decolorization
23-11-2010 | Ola M. Gomaa, Osama A. Momtaz, Hussein Abd El Kareem, Riham Fathy, World Journal of Microbiology and Biotechnology, 2010
Twenty-two local brown rot fungal isolates were obtained from 5 different environmental sources. Fourteen isolates were presumptively identified as Aspergillus sp. and eight as Penicillium sp. using mycelium and spore morphology. All the fungal isolates were screened for their ability to ...
Hypocholesterolemic Activity from the Leaf Extracts of Cnidoscolus chayamansa
22-11-2010 | Lylia Miranda-Velasquez, Azucena Oranday-Cardenas, Hector Lozano-Garza, Catalina Rivas-Morales, German Chamorro-Ceva ..., Plant Foods for Human Nutrition (Formerly Qualitas Plantarum), 2010
The aim of this study was to determine the hypocholesterolemic activity of Cnidoscolus chayamansa. In an in vivo model, high-cholesterol diet administered to mice Balb/c induced hypercholesterolemia. Three extracts from Cnidoscolus chayamansa (ethanol, methanol and an aqueous extract) were ...
Stereospecificity of isotopic exchange of C-α-protons of glycine catalyzed by three PLP-dependent lyases: the unusual case of tyrosine phenol-lyase
22-11-2010 | Vitalia V. Koulikova, Lyudmila N. Zakomirdina, Olga I. Gogoleva, Marina A. Tsvetikova, Elena A. Morozova, Vsevolod V ..., Amino Acids, 2010
A comparative study of the kinetics and stereospecificity of isotopic exchange of the pro-2R- and pro-2S protons of glycine in 2H2O under the action of tyrosine phenol-lyase (TPL), tryptophan indole-lyase (TIL) and methionine γ-lyase (MGL) was undertaken. The kinetics of exchange was ...
Specific Poly-phenolic Compounds in Cell Culture of Vitis vinifera L. cv. Gamay Fréaux
09-11-2010 | Inga Mewis, Iryna M. Smetanska, Carsten T. Müller, Christian Ulrichs, Applied Biochemistry and Biotechnology, 2010
Cell cultures established from plants represent an attractive alternative to whole plants for effective production of bioactive secondary metabolites. Cell culture from Vitis vinifera L. cv. Gamay Fréaux accumulated high amounts of hydroxycinnamic acid derivatives and anthocyanins. Two new ...
Behavior and Properties in Aqueous Solution of Biopolymers Isolated from Urban Refuse
08-11-2010 | Enzo Montoneri; Vittorio Boffa; Piero Savarino; Daniele G. Perrone; Corrado Montoneri; Raniero Mendichi; Edgar J. Ac ..., Biomacromolecules, 2010
Acid soluble biopolymeric substances (SBP) were isolated from different urban biowastes comprised of a range of materials available from metropolitan areas. These biowastes provided products with a chemical nature and solubility properties changing over a wide range and, thus, allowed to ...
Hemorheological Effects of Ortho-Isobornyl Phenol Derivative under Conditions of Brain Ischemia in Rats
07-11-2010 | M. B. Plotnikov, V. I. Smolyakova, I. S. Ivanov, G. A. Chernisheva, A. V. Kuchin, I. J. Chukicheva, E. A. Krasnov, Bulletin of Experimental Biology and Medicine, 2010
Hemorheological activity of 4-methyl-2,6-di-isobornyl phenol, a new o-isobornyl phenol derivative, was studied under conditions of experimental prolonged partial cerebral ischemia. Brain ischemia is associated with hemorheological disorders which can be characterized as blood hyperviscosity ...
Biotransformation of 4-halophenols to 4-halocatechols using Escherichia coli expressing 4-hydroxyphenylacetate 3-hydroxylase
06-11-2010 | Lydie Coulombel, Louise C. Nolan, Jasmina Nikodinovic, Evelyn M. Doyle, Kevin E. O’Connor, Applied Microbiology and Biotechnology, 2010
Escherichia coli cells, expressing 4-hydroxyphenylacetate 3-hydroxylase, fully transformed 4-halogenated phenols to their equivalent catechols as single products in shaken flasks. 4-Fluorophenol was transformed at a rate 1.6, 1.8, and 3.4-fold higher than the biotransformation of 4-chloro-, ...
Effect of Biosurfactants on Laccase Production and Phenol Biodegradation in Solid-State Fermentation
05-11-2010 | Mei-Fang Zhou, Xing-Zhong Yuan, Hua Zhong, Zhi-Feng Liu, Hui Li, Li-Li Jiang, Guang-Ming Zeng, Applied Biochemistry and Biotechnology, 2010
The effects of two biosurfactants, tea saponin (TS) and rhamnolipid (RL), on the production of laccase and the degradation of phenol by P. simplicissimum were investigated in solid-state fermentation consisting of rice straw, rice bran, and sawdust. Firstly, the effects of phenol on the ...
Characterization of Outer Membrane Proteins of Escherichia Coli in Response to Phenol Stress
23-10-2010 | Dan-Feng Zhang, Hui Li, Xiang-Min Lin, San-Ying Wang, Xuan-Xian Peng, Current Microbiology, 2010
Gram-negative bacteria are generally more tolerant to disinfectants than Gram-positive bacteria due to outer membrane (OM) barrier, but the tolerant mechanism is not well characterized. We have utilized comparative proteomic methodologies to characterize the OM proteins of E. coli K-12 K99+ ...
Triostin A derived hybrid for simultaneous DNA binding and metal coordination
21-10-2010 | Eike-F. Sachs, André Nadler, Ulf Diederichsen, Amino Acids, 2010
The natural product triostin A is known as an antibiotic based on specific DNA recognition. Structurally, a bicyclic depsipeptide backbone provides a well-defined scaffold preorganizing the recognition motifs for bisintercalation. Replacing the intercalating quinoxaline moieties of triostin A ...
