A novel bioflocculant-producing bacterial strain B-28 was screened from contaminative soils by gas oil wastewater. The optimum carbon sources, nitrogen sources, metal ions and initial pH were glucose, yeast extract, 2 ml 0.1% FeCl3 and 6-8, respectively. And at the optimal couture conditions, flocculating activity reached its maximum flocculating activity of 97.2% at 72 h. This indicated that the...
Three different protein fractions were isolated from barley bran and flour. Electrophoretic properties, including molecular weight and fraction patterns of barley protein isolates (BPIs), were characterized and examined by Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The functional properties of BPIs also were investigated, and then compared with soy, and zein protein. SDS-PAGE...
Electro-bioremediation is an efficient method for removal or degradation of soil organic pollutants. Oil contaminants widely exist in many regions of the world and pose persistent risk on human health. In this study, we performed a number of experiments to examine the effectiveness of electro-bioremediation on an oil-contaminated soil in a perspex cell, where oil-degrading bacteria were present. During...
Environmental accidents occur frequently in China in recent years. A quick estimation of the extent and distribution of contamination after environmental accidents is important for immediate treatment of the contaminated sites. This paper proposed a methodology to estimate the velocity and maximum infiltration depth of NAPL after spill accidents to provide quick and quantitative information for the...
