To study the efficacy of chlorine dioxide in inactivation antibiotic-resistant bacteria soil, resistant to penicillin, amoxicillin or streptomycin were screened out from soils around a hennery. The effects dosage, contact time and pH value on killing rates investigated by batch experiments. community composition before after was analyzed high-throughput genetic sequencing. results showed that are common widespread soil most species is Staphylococcus aureus. More than 99% could be killed at 5 mg L-1 within 30 min under neutral conditions. log declined slightly when changed 4 9. dominant genus Sphingomonas, which sensitive inactivated easily similar Arthrobacter Massilia. However, Micromonosporaceae Thaumarchaeota more other species, their relative abundance increased disinfection.
