| This study was carried out to investigate the population densities, R/S ratios, and identification of heterotrophic bacteria on the rhizosphere soil of halophyte Suaeda japonica found on the western and southern mudflats of Korea. The population densities of aerobic and anaerobic heterotrophic bacteria on the rhizosphere soil of Suaeda japonica were in the range of $1.3;{pm};0.3;{ imes};10^6;{sim};6.3;{pm};3.3;{ imes};10^7;and;2.8;{pm};1.3;{ imes};10^4;{sim};1.8;{pm};0.7;{ imes};10^7;cfu;g^{-1};d.;wt.$, respectively. In case of physiologically specific bacteria, population densities of amylolytic bacteria on the rhizosphere soil of Suaeda japonica were in the range of $4.4;{pm};0.6;{ imes};10^6;{sim};2.5;{pm};1.2;{ imes};10^7;cfu;g^{-1};d.;wt.$, those of cellulolytic bacteria were from $8.5;{pm};6.0;{ imes};10^4;{sim};2.3;{pm};1.6;{ imes};10^6;cfu;g^{-1};d.;wt.$, and those of proteolytic bacteria were from $3.8;{pm};1.8;{ imes};10^5;{sim};4.2;{pm};2.9;{ imes};10^6;cfu;g^{-1};d.;wt.$, respectively. The R/S ratios were ranged from 2.33 to 2.39. Among eleven isolates from the roots of halophyte Suaeda japonica of Goheung bay by using 16S rDNA analysis, five clones were closely related to ${gamma}-Proteobacteria$ group and six clones were closely related to ${alpha}-Proteobacteria$ group. Among four isolates from Suncheon bay, two strains were related to ${gamma}-Proteobacteria$ group and another two were related to Actinobacteria and Bacilli group, respectively. |
