In order to provide some support for economically and effectively resolving the problem of water pollution around the islands in the South China Sea, biological nitrogen removal (BNR) performance and biotechnological characterization of the FSBR filled with abandoned coral sand were investigated. The results showed that the TN removal efficiency of the FSBR with a good performance of simultaneous...
Extracellular polymeric substances (EPS) contain a large amount of phosphorus, but the content of extracellular phosphorus in activated sludge and the decomposition of extracellular polyphosphate (polyP) in extraction process is still unclear. In this study, the extraction efficiencies of extracellular phosphorus using sonication, cation exchange resin (CER) and sonication-CER methods were investigated...
The mediator complex, a conserved assembly of multi-functional proteins, is required for the transcription of almost all protein-encoding genes in eukaryotes. In this report, 36 mediator complex subunit transcripts in Rehmannia glutinosa were identified from a leaf and tuberous root EST database. Nine of these transcripts had integrated open-reading frames (ORFs). A comparison of predicted amino acid...
Five pathogen-free miniature pigs (minipigs) were infected with the virulent strain SH08 of Streptococcus suis 2 (SS2) by intramuscular injection. The pigs died consecutively within 72 h after the challenge. An additional five non-infected pigs were euthanised and used as controls. Microstructural observations showed that degeneration, bleeding, congestion, cellular necrosis, and an increase in inflammatory...
