Research ArticleOpen accessIn the abstractContrasting Effects of Metal Contaminations and Soil Liming on Cations Exchange Capacity and Global DNA Methylation in Betula papyrifera Populations from a Mining RegionGabriel Theriault, Kabwe NkongoloThe Greater Sudbury Region in Northern Ontario (Canada) has been one of the most contaminated regions in the world. Soil liming with dolomitic limestone applications has decreased significantly the level of soil acidity resulting in forest regeneration. This reclamation process does not affect the level of soil metal contamination but results in metals availability decrement. The coping mechanisms of birch … …American Journal of Environmental Sciences, Vol. 12, Issue 2 · 11 Apr 2016 · 7,539 accessesView PDFCite
Research ArticleOpen accessIn the abstractEssential Oil Chemical Composition of Myrtle Growing in Northeastern Algeria and Estimation of its Antibacterial EffectivenessBarhouchi Badra, Aouadi Saoudi, Abdi AkilaThe aim of this study is to determine the antibacterial effectiveness of leaves essential oil extracted from myrtle growing in Algeria. A cluster analysis of soil and water was effectuated for performing chemical and granulometric analyses. The essential oil was isolated from leaves by hydro distillation and analyzed by Gas Chromatography-Mass Spectrometry (GC/MS). The leaves yield reached a peak at … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 2 · 5 Apr 2016 · 8,360 accessesView PDFCite
Research ArticleOpen accessIn the abstractSodium L-Glutamate-Induced Physiological Changes in Lactobacillus Brevis NCL912 During GABA Production Under Acidic ConditionsGui-Dong Huang, Jian Mao, Zhongwei Ji, Askaer AlatiPrevious studies showed that γ-Aminobutyric Acid (GABA) can protect some GABA-producing bacteria against acid stress through glutamate decarboxylation. However, the acid stress mechanism is a comprehensive network related to numerous genes and proteins. Other than the Glutamate Decarboxylase (GAD)/GABA antiporter system, limited information is available about the physiological modifications that occur in Lactobacillus brevis during GABA production under acidic conditions. … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 4 · 22 Dec 2014 · 7,325 accessesView PDFCite
Research ArticleOpen accessIn the abstractLIQUID AND VAPOUR PHASE ANTIBACTERIAL ACTIVITY OF EUCALYPTUS GLOBULUS ESSENTIAL OIL = SUSCEPTIBILITY OF SELECTED RESPIRATORY TRACT PATHOGENSBoukhatem Mohamed Nadjib, Ferhat Mohamed Amine, Kameli Abdelkrim et al.Essential Oils (EO) produced by medicinal plants have been traditionally used for respiratory tract infections and are used nowadays as ethical medicines for colds. Although several studies of Eucalyptus Globulus Labill. Essential Oil (EGEO) have been reported, there are no reports describing vapour activity of EGEO against bacterial respiratory tract pathogens. The aim of this study was to test the … …American Journal of Infectious Diseases, Vol. 10, Issue 3 · 3 Sep 2014 · 13,326 accessesView PDFCite
Research ArticleOpen accessIn the abstractPHENOTYPICAL AND MASS SPECTRAL ASSESSMENT METHODS FOR IDENTIFICATION OF SOME CONTAGIOUS MASTITIS PATHOGENSA. El Behiry, Rasha Nabil Zahran, Eman Marzouk, Musaad Al-DabibMastitis is one of the most economic disease affecting dairy cows worldwide. Identification of mastitis pathogens still depends principally on culture and phenotypical method, which is a difficult and time-consuming. Newly, microbiologists have focused their attention on the use of Mass Spectrometry (MS) for microbial identification, especially Matrix Assisted Laser Desorption Ionization Time-Of-Flight (MALDI-TOF). Therefore, this study was designated to … …Current Research in Microbiology, Vol. 5, Issue 1 · 29 May 2014 · 8,138 accessesView PDFCite
Research ArticleOpen accessIn the abstractA BIOPHYSIOCHEMICAL ANALYSIS OF SETTLED LIVESTOCK AND POULTRY HOUSING DUSTSCarresse Gerald, Christi McPherson, Tha’Mes McDaniel et al.The levels and composition of agricultural dusts are influenced by animal species, production strategy, housing type and ventilation efficiency. Agricultural dust within animal houses is complex and consists of feed particles, microbes and their products, dander, fecal matter, gases, metals and other organic and inorganic components. Livestock and poultry production facilities may be categorized as confinement, semi-confinement or pasture-based. Characterization … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 16 Jan 2014 · 8,085 accessesView PDFCite
Research ArticleOpen accessIn the abstractCHEMICAL COMPOSITION, ANTIMICROBIAL, ANTIOXIDANT AND CYTOTOXIC ACTIVITIES OF EUCALYPTUS CHAPMANIANA GROWN IN IRAQGhassan Mohammad Sulaiman, Thorria Radam Marzoog, Wasnaa Hatif Mohammed, Renzo BagnatiThe chemical composition of the essential oils extracted from immature flowers, leaves and seeds of Eucalyptus chapmaniana grown in Iraq were analyzed for the first time by gas chromatography/mass spectrometry. Twenty-four different compounds were identified and the predominant compound is eucalyptol, which accounted for 59.9, 55.6 and 8.6% of total compounds, respectively. To asses the possible therapeutic uses of the … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 27 Dec 2013 · 7,701 accessesView PDFCite
