Isolation and identification of two aerobic denitrifiers with high efficiency in the removal of N from simulated wastewater
两株高效好氧反硝化细菌的分离鉴定及其脱氮效率

Two strains of aerobic denitrifiers were isolated from flooded paddy soil and active sludge,respectively.The two strains,coded as ZW23 and ZW27,are facultative bacteria.In the light of their morphological and physiological features as well as their 16S rDNA sequences,they were identified as Pseudomonas pseudoalcaligenes and Pseudomonas mendocina.Under aerobic incubation conditions,N loss through denitrification in the liquid culture medium inoculated with ZW23 and ZW27 reached 66.43% and 65.54% in 12 hours,...
