Assay of nitrification potentials in sewage sludge by Jöngren, Caroline

“…Application to arable land is though controversial as SS can contain contains such as human pathogens, heavy metals and xenobiotics. Post-treatment processes of SS such as long term storage which can reduce pathogenic bacteria before application to soil implicate a risk of nitrogen (N) losses via emissions of the greenhouse gas nitrous oxide (N2O) and leaching of nitrate (NO3-). …”

Tolerance and Cadmium (Cd) Immobilization by Native Bacteria Isolated in Cocoa Soils with Increased Metal Content by Feria Cáceres, Pedro F., Penagos Velez, Lucas, Moreno Herrera, Claudia X.

“…Twelve cadmium native bacteria previously isolated in soils of cocoa farms located in the western Colombian Andes (Santander), and tolerant to 2500 M CdCl2 (120 mg Cd/L), were chosen in order to test their tolerance and Cd immobilization using liquid culture medium (Nutritive broth) at different concentrations of heavy metals. Furthermore, in the greenhouse experiments, the strains Exiguobacterium sp. (11-4A), Klebsiella variicola sp. (18-4B), and Enterobacter sp. (29-4B) were applied in combined treatments using CCN51 cacao genotype seeds grown in soil with different concentrations of Cd. …”
