title: [Screening, combination of microbial deodorizer and the optimization of its deodorizing conditions].
abstract: In order to obtain the candidate strains of deodorizing microorganism, three optimization strains with relatively higher deodorizing capacity were isolated from landfill leachate, which were given the labels of CC3, CC7, CC13 and CC16. According to the results of morphological observation, physiological and biochemical tests, 16S rDNA sequence homology analysis, the strains CC3, CC7, CC13 and CC16 were identified as Pediococcus acidilactici, Bacillus megaterium, Lactobacillus acidophilus and Alcaligenes faecalis respectively. When the strains CC7, CC13 and CC16 were mixed with the inoculation rate was 1:1.5:0.5, the removal rates of ammonia and hydrogen sulfide were 83.56% and 70.25%. The optimal conditions of deodorizing by single factor test were deodorization time of 60 hours, sausage of 5%, temperature of 30 degrees C, initial pH of 6.5.
