[Denitrifying bacteria isolated from river sediment and its nitrogen and phosphorus removal capacity from river water].

20 strains of bacteria were isolated from river sediment using enrichment culture medium for denitrification, and the denitrification intensity was determined. F10, one of bacteria strain, was identified having the highest denitrifying intensity, and further used to test its role in the removing of nitrogen and phosphorus from wastewater in laboratory. By checking the individual morphology, colony culture characteristics, DNA sequencing and 16S rDNA gene bank, F10 was identified as Alcaligenes faecalis, and its denitrifying intensity was 63.

Effect of adding Lactobacillus plantarum and soluble carbohydrates to swine manure on odorous compounds, chemical composition and indigenous flora.

Manure odor, which results in the increasing complaints and lawsuits, has increased the tension among swine producers and surrounding residents. The effects of Lactobacillus plantarum and different rates of soluble carbohydrates additions to swine manure on odorous compounds, chemical compounds and indigenous flora were evaluated. Additions were calculated on dried manure weight basis.
