一株异养硝化真菌的筛选及其特性
Isolation and Characteristic of a New Heterotrophic Nitrification Fungus
摘要
Abstract
A heterotrophic nitrification fungus with high efficiency of removing NH+4 ‐N ,was isolated and purified from the activated sludge of coking wastewater .By 26S rRNA gene sequence analysis ,and combined with colony morphology ,physiological and biochemical characteristics ,it was identified as Penicillium fungus and named L1 .The culture medium was optimized to select the optimum source of carbon and nitrogen ,n(C)/n(N) and initial pH .In the optimized medium with initial concentration of 130 mg/L ammonia ,L1 degraded the ammonia to 5.61 mg/L after 36 h ,the degradation rate was 95.68% ,with almost no accumulation of nitrite and nitrate .On the complex medium containing 100 mg/L ammonia and 200~1 000 mg/L aniline ,L1 degraded both of them with a good effect .关键词
