Enhanced biodegradation of pentachlorophenol in unsaturated soil using reversed field electrokinetics.
|Abstract||This study investigated the use of electrokinetics in unsaturated soil to promote biodegradation of pentachlorophenol through increased contact between bacteria and contaminant. Soil microcosms, contaminated with approximately 100 mg kg(-1) pentachlorophenol (containing [(14)C]-PCP as a tracer), and inoculated with a specific pentachlorophenol-degrading bacterium (Sphingobium sp. UG30-1 x 10(8) cfu g(-1)) were subjected to constant and regularly ... [truncated at 450 characters in length]|

Estrogen concentration affects its biodegradation rate in activated sludge.
|Abstract||The effect of concentration on the biodegradation rate of the steroid estrogens, estrone (E1) and 17-alpha-ethinylestradiol (EE2), was studied in batch and continuous-flow reactor systems using fresh activated sludge from two sewage treatment plants. Between the concentrations of 0.03 to 10 μg/L in the batch system no consistent difference was found in the biodegradation rates for either estrogen. The biodegradation half-life was 0.3 to 0.7 h for ... [truncated at 450 characters in length]|

A comparison between cell viability of chondrocytes on a biodegradable polyester urethane scaffold and alginate beads in different oxygen tension and pH
|Abstract||Cartilage is a tissue that has a low potential for self-repair. One of the methods for improvement of regeneration and metabolism in cartilge, is to stimulate physical factors on chondrocytes as cartilage based cells. In this research, two physical factors, oxygen tension and pH, were changed to measure the cell viability of chondrocytes on Degrapol®, as a biodegradable polyurethane (DBS), and alginate scaffolds and cell viability onto these subs ...

In vitro biodegradation of three brushite calcium phosphate cements by a macrophage cell-line.
|Abstract||Depending upon local conditions, brushite (CaHPO4 x 2 H2O) cements may be largely resorbed or (following hydrolysis to hydroxyapatite) remain stable in vivo. To determine which factors influence cement resorption, previous studies have investigated the solution-driven degradation of brushite cements in vitro in the absence of any cells. However, the mechanism of cell-mediated biodegradation of the brushite cement is still unknown. The aim of the ... [truncated at 450 characters in length]|
