Draft Genome Sequence of a Plant Growth-Promoting Rhizobacterium, Serratia fonticola Strain AU-P3(3)
Plant growth-promoting rhizobacteria (PGPR), found in the rhizospheric region of plants, not only suppress plant disease, but also directly improve plant health by improving the availability of nutrients and by providing phytostimulants. Herein, we report the high-quality genome sequence of Serratia fonticola strain AU-P3(3), a PGPR of the pea plant, which confers phosphate solubilization, indo...
Based on field data from a medium scale ammonia based milk refrigeration plant located in northern part of India, a trans-critical CO2 based heat pump system is conceptualized to utilize the waste heat from the plant to improve overall coefficient of performance. Year round plant operating data is collected. The plant handles in the range of 0.1 to 0.15 million liters of milk and milk products ...
One of the earliest detectable events during plant-pathogen interaction is a rapid increase in ethylene biosynthesis. This gaseous plant stress hormone may be a signal for plants to activate defense mechanisms against invading pathogens such as bacteria, fungi, and viruses. The effect of ethylene on four plant genes involved in three separate plant defense response pathways was examined; these ...
Ambient ammonia monitoring using Ogawa passive samplers was conducted in the Four Corners area and eastern Oklahoma, USA during 2007. The resulting data will be useful in the multipollutant management of ozone, nitrogen oxides, and visibility (atmospheric regional haze) in the Four Corners area, an area with growing oil/gas production and increasing coal-based power plant construction. The pass...
BACKGROUND Archaea are important to the carbon and nitrogen cycles, but it remains uncertain how rising atmospheric carbon dioxide concentrations ([CO(2)]) will influence the structure and function of soil archaeal communities. METHODOLOGY/PRINCIPAL FINDINGS We measured abundances of archaeal and bacterial 16S rRNA and amoA genes, phylogenies of archaeal 16S rRNA and amoA genes, concentration...
Background. The decline of submerged plant populations due to high heavy metal (e.g., Cu) levels in sediments and ammonia nitrogen (ammonia-N) accumulation in the freshwater column has become a significant global problem. Previous studies have evaluated the effect of ammonia-N on submerged macrophytes, but few have focused on the influence of sediment Cu on submerged macrophytes and their combi...
In this study, an indoor fish farm was selected to assess the biological treatment of the waste effluents. The purification lagoon surface was completely grown by target species, Nasturtium aquaticum. Six stations were selected as the water source, the farm outlet, the starting point of outlet water to the lagoon and three next other sampling stations. The averages of many chemical parameters ...
Selected alkaloids are chromatographed on cyanopropyl-silica thin layers using various nonaqueous and aqueous eluents. Because of the strong retention of these basic compounds, nonaqueous eluents containing medium polar diluents, strongly polar modifiers, and silanol blockers (ammonia or diethylamine) are required for separation. Likewise, aqueous eluents containing modifiers (acetonitrile, met...
