Three species of nitrifying bacteria were tested for the ability to degrade the halocarbon fumigants methyl bromide, 1,2-dichloropropane, and 1,2-dibromo-3-chloropropane. The soil nitrifiers Nitrosomonas europaea and Nitrosolobus multiformis degraded all three fumigants, while the marine nitrifier Nitrosococcus oceanus degraded only methyl bromide under the conditions tested. Inhibition of biodegradation by allylthiourea and acetylene, specific inhibitors of ammonia monooxygenase, suggests that ammonia monooxygenase is the enzyme which catalyzes fumigant degradation.
对三种硝化细菌降解卤代烃熏蒸剂甲基溴、1,2 - 二氯丙烷和1,2 - 二溴 - 3 - 氯丙烷的能力进行了测试。土壤硝化细菌欧洲亚硝化单胞菌和多形亚硝化螺菌能降解所有这三种熏蒸剂，而海洋硝化细菌海洋亚硝化球菌在所测试的条件下仅能降解甲基溴。氨单加氧酶的特异性抑制剂烯丙基硫脲和乙炔对生物降解的抑制作用表明，氨单加氧酶是催化熏蒸剂降解的酶。
