Isolation, identification, and bioactivity of steroids isolates from Hydrilla verticillata petroleum ether fraction

Life cycle assessment of nutrient remediation and bioenergy production potential from the harvest of hydrilla (Hydrilla verticillata).

Hydrilla (Hydrilla verticillata) is one of the world's most problematic invasive aquatic plants. Although management of hydrilla overgrowth has often been based on use of chemical herbicides, issues such as the emergence of herbicide-resistant hydrilla biotypes and the need for in situ nutrient remediation strategies have together raised interest in the use of harvester machines as an alternati...

Isolation, identification, and antimicrobial susceptibility of Clostridium perfringens isolates from acute necrotic enteritis of broiler chickens

The aim of this study was to isolate, identify and determine the antimicrobial susceptibility of Clostridium perfringens (CP) isolates from acute necrotic enteritis of broiler chickens. All broiler carcasses diagnosed as necrotic enteritis (NE) were sampled, subjected to microbial tests and 40 isolates were identified according to standard procedures. The antimicrobial susceptibility of CP isol...

The Effect of Petroleum Ether Fraction of Teucrium polium Extract on Laboratory Mouse Liver

Background & Aims: Teucrium polium (TP) is amongst the commonly used remedies in traditional medicine. Some reports have claimed hepatotoxicity of TP but other reports have not supported it. This study was designed to evaluate the probable hepatotoxicity of TP. Methods: Petroleum ether fraction of TP was dissolved in DMSO and the final concentration was adjusted by diluting in physiologic salin...

Effect of Aquathol K on Hydrilla verticillata (L.F.) Royle

A recently synthesized herbicide Aquathol K was tested on the water weed Hydrilla verticil/ata. Results from the laboraoty tests indicated that Aquathol K with concentrations ranging from 1.0 mg/l to 2.0 mg/l can kill this weed. EVidently, 100% injury was achieved within 10 days for the plants treated with the highest concentration., 2. 0 mg/l of Aquathol K. The rate of 100% injury was recorded...
