Abstract: Using DAPI epifluorescence microscopy,we investigated the abundance and biomass as well as the distribution of benthic heterotrophic bacteria based on the sediments samples collected in June 2007 and July 2008 in the Yellow Sea.The abundance of benthic bacteria in 2007 was(1.13±0.39)×108cells/cm3and the biomass was(49.63±17.26)gC/cm3,while in 2008 the bacterial standing crops were about 43% lower than those in 2007.In the southern Yellow Sea the benthic bacterial standing crops were respectively 8%(in 2007)and 13%(in 2008)lower than those in the northern Yellow Sea,and were respectively 10% and 37% higher in the Yellow Sea Cold Water Mass(YSCWM)than those in the area outside the YSCWM.Moreover,the benthic bacterial standing crops were distinctly higher in the coastal region than in the YSCWM in the northern Yellow Sea,while in the southern Yellow Sea the pattern was exactly opposite.Statistical analyses showed that the benthic bacterial abundance had a significantly positive correlation with the contents of sediment chlorophyll a in the northern Yellow Sea in 2007,while that in the southern Yellow Sea had a significantly positive correlation with bottom water salinity and sediment organic matter contents.In 2008,no relationship was observed in the northern Yellow Sea,while in the southern Yellow Sea there was a significantly negative correlation between the abundance and bottom water chlorophyll concentrations,indicating inhibition of bacterial growth caused by the green algal bloom of Ulva prolifera.
