Surface water samples from downstream and estuarine areas of Jiulong River were collected in August 2011 and May 2012 for detecting sulfonamide antibiotic residues and isolating sulfamethazine-resistant bacteria. Sulfamethazine was detected in all samples in May 2012 at an average concentration of 78.3 ng L(-1), which was the highest among the nine(More)
The effects of zinc (Zn) on nitrous oxide (N2O) fluxes from coastal loam soil and the abundances of soil nitrifier and denitrifier were studied in a tidal microcosm receiving livestock wastewater with different Zn levels. Soil N2O emission significantly increased due to discharge of wastewater rich in ammonia (NH4+-N) while the continuous measurements of(More)
Two bacterial strains, 2-2-12-1T and 2-2-12-2, were isolated from the estuary of the Jiulong River, south-east China. Cells were Gram-stain-negative, non-motile, short rods without flagella. Growth occurred at 25-45 °C, at pH 5.0-9.0 and with 0.5-2 % (w/v) NaCl. The bacteria were unable to reduce nitrate. The predominant fatty acids were C19 : 0 cyclo ω9c(More)
