Research ArticleOpen accessIn the abstractOptimization of Cultural Conditions for Production of Exopolysaccaride by Halomonas marina HMA 103 under Batch-CultureArundhati Pal, Amrita Biswas, Sriya Chatterjee, A. K. PaulA moderately halophilic bacterium, Halomonas marina HMA 103 (MTCC 8968) accumulating intracellular polyesters also produced significant amount of exopolysaccharides (EPS) under batch-culture. Production of EPS by the bacterium was more or less parallel with the growth in modified basal synthetic medium. During growth, it produced 0.46 g/L of EPS after 50 h of incubation and was accompanied by the complete … …Current Research in Microbiology, Vol. 6, Issue 2 · 27 Jul 2015 · 7,936 accessesView PDFCite
Research ArticleOpen accessIn the abstractFeatures of Microelement Composition of Ordinary Chernozems of the Azov and Lower Don RegionsTatiana M. Minkina, Nikolay N. Miroshnichenko, Aleksandr I. Fateev et al.Ordinary chernozems in the Azov Plain have a low background content of mobile zinc compounds, a sufficient supply with copper and an increased content of lead compounds. This specificity of the regional microelement composition is due to the high carbonate content in the soil profiles, the natural enrichment of littoral geochemical landscapes and the effect of the significant sources of … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 3 · 27 Jul 2015 · 7,398 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Fungal Communities in Limed and Unlimed Lands Contaminated with Metals: Phospholipid Fatty Acid (PLFA) Analysis and Soil RespirationKassandre Goupil, Kabwe K. Nkongolo, Sabah NasserullaNorthern Ontario (Canada) especially the Greater Sudbury region is highly known for its nickel, copper and other metal deposits. The mining, roasting and smelting of these elements have caused disastrous effects on the vegetation and overall environment. Dolomitic lime which contains calcium and magnesium carbonate was applied to soils from 1980 to 1995 at different locations across Northern Ontario. The … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 2 · 26 May 2015 · 8,100 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Heavy Metals in the Surface Sediments of the Main Wadis in the Region of Meknes-MoroccoA. Lammini, A. Dehbi, H. Omari, A. AbdallaouiBecause of their growing demographic and industrial expansion, the urban areas of the city of Meknes are likely to disturb the ecological balance of watercourse. In the present work, we had evaluate the degree of sediment’s contamination by heavy metals (Al, Cd, Cu, Fe, Mn, Pb and Zn) in the main wadis of the Meknes region (Boufekrane, Wislane and Toulal) … …Current Research in Geoscience, Vol. 4, Issue 2 · 29 Apr 2015 · 7,112 accessesView PDFCite
Research ArticleOpen accessIn the abstractChanges in the Rumen Papillae During the Periparturient Transition in Holstein Dairy Cows are Accompanied by Changes in Abundance of Proteins Involved in Intracellular pH Regulation, But not SCFA TransportAnne Hermen Laarman, Adam Kleinberg, Michael Alexander Steele et al.The objective of this study was to examine changes in SCFA transport capacity in the rumen epithelium during the parturition transition period. Twelve pregnant, cannulated primiparous and multiparous cows were fed a standard Total Mixed Ration (TMR) for the duration of the dry period; after calving, all cows were switched to an early lactation TMR. Rumen pH, fluid and biopsies … …American Journal of Animal and Veterinary Sciences, Vol. 10, Issue 1 · 31 Mar 2015 · 7,554 accessesView PDFCite
Research ArticleOpen accessIn the abstractASCORBIC ACID FOLIIAR SPRAY COUNTERACTING EFFECT OF SALINITY ON GROWTH, NUTRIENTS CONCENTRATIONS, PHOTOSYNTHESIS, ANTIOXIDANT ACTIVITIES AND LIPID PEROXIDATION OF BEAN (PHASEULUS VULGARIS L.) CULTIVARSZeinab A. Salama, El-Zanaty A.A. Abou El-Nour, Mohamed M. El Fouly, Alaa A. GaafarA water culture experiment was carried out in the Department of Fertilization Technology at National Research Centre, Cairo, Egypt, to investigate the effect of Ascorbic Acid (AsA) foliar application and salinity stress (100 ppm and 100 mmoL NaCl) on growth, nutrients concentration and some biochemical parameters of two kidney bean (Phaseulus Vulgaris L.) cultivars. Salinity caused significant reduction in growth … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 16 May 2014 · 7,906 accessesView PDFCite
Research ArticleOpen accessIn the abstractINFLUENCE OF INCUBATION PERIOD, TEMPERATURE AND DIFFERENT PHOSPHATE LEVELS ON PHOSPHATE ADSORPTION IN SOILA. Rajput, Q. A. Panhwar, U. A. Naher et al.Phosphorus (P) is the most important element after nitrogen but P sorption properties are poorly documented in many soils. In this study, P sorption capacity in relation to incubation period and temperature under various P levels were determined for two different soil series (Rustam and Miani). Phosphorus was added at 5, 10, 25, 50, 100, 250, 500 and 1000 µg … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 13 Feb 2014 · 8,294 accessesView PDFCite
