Isolation and characterization of Clostridium difficile from a small survey of wastewater, food and animals in New Zealand.

abstract：UNLABELLED:The mechanisms and organisms involved in the natural formation of volatile organohalogen compounds (VOX) are largely unknown. We provide evidence that the common and widespread soil bacterium Sinorhizobium meliloti strain 1021 is capable of producing up to 3338·6 ± 327·8 ng l(-1) headspace volume of chlorofo...
