Transformation of Organoarsenical Species by the Microflora of Freshwater Crayfish

Journal of Agricultural and Food Chemistry, 2005
A study of the transformation of arsenic species by the microflora of the freshwater crayfish Procambarus clarkii was carried out. The study of the degradation of AB (arsenobetaine) was performed in aerobic conditions in two culture media (tryptic soy broth and saline medium) at two temperatures (30 and 8 degrees C).
