摘要:
为了探索微生物除臭菌对畜禽粪便中氨气的处理效果，采用富集、平板划线分离法，从堆肥样品中共分离出25株菌株，通过氨气选择性培养基筛选出1株高效抑制氨气的菌株，命名为菌株YS1。根据形态学观察、内部转录间隔区(ITS)rDNA序列同源性比对、系统进化分析对菌株YS1进行多相鉴定，初步鉴定该菌株为尖孢镰刀菌(Fusarium oxysporum)。结果表明，菌株YS1接种到硝化培养基后反应96 h，NH+4-N含量从100.0 mg/L下降至9.4 mg/L，NH+4-N 的去除率达90.6%，体系总氮削减率达58.6%。在反硝化培养基中反应96 h，NO-3-N的浓度由初始的993 mg/L下降为17.6 mg/L，降解率达82.3%，体系总氮削减率达35.4%。溶血性试验表明，YS1菌株无溶血性。
