A simple and efficient method for concentration of ocean viruses by chemical flocculation
Ocean viruses alter ecosystems through host mortality, horizontal gene transfer and by facilitating remineralization of limiting nutrients. However, the study of wild viral populations is limited by inefficient and unreliable concentration techniques. Here, we develop a new technique to recover viruses from natural waters using iron-based flocculation and large-pore-size filtration, followed by...
متن کاملAssessment of recovery efficiency of beef extract reagents for concentrating viruses from municipal wastewater sludge solids by the organic flocculation procedure.
This study was designed to assess the capacity of beef extract reagents to form flocs suitable for virus adsorption. Reagent comparisons resulted in the establishment of a modified organic flocculation procedure to concentrate viruses desorbed from sewage sludge solids with currently available modified powdered beef extracts. The method, based on supplementation with paste beef extract floc, ac...
متن کاملEffect of ammonium sulfate fertilization on bahiagrass quality and copper metabolism in grazing beef cattle.
To assess the impact of S fertilization on bahiagrass (Paspalum notatum) quality and Cu metabolism in cattle, two studies were conducted during the summer grazing season (1999 and 2000). Pasture replicates (16.2 ha; n = 2/treatment) received the same fertilizer treatment in each growing season, consisting of 1) 67 kg N/ha from ammonium sulfate (AS), 2) 67 kg N/ha from ammonium nitrate (AN), and...
