Abundance and Biomass of Benthic Heterotrophic Bacteria in Jiaozhou Bay, China

摘要

The abundance and biomass of benthic heterotrophic bacteria were investigated for the 4 typical sampling stations in the northern muddy part of Jiaozhou Bay, estuary of the Dagu River, raft culturing and nearby areas of Huangdao in March, June, August and December, 2002. The abundance and biomass range from 0.98 x 10~7 to 16.87 x 10~7 cells g~(-1) sediment and 0.45 to 7.08 μg Cg~(-1) sediment, respectively. Correlation analysis showed that heterotrophic bacterial abundance and biomass are significantly correlated to water temperature (R =0.79 and 0.83, respectively, P < 0.01).
