Population densities of aerobic heterotrophic bacteria by plate counting method were in the range of 3.5 ± 0.2 × 106~1.8 ± 0.7 × 107 cfu g−1 dry wt. from the grasses of Gunsan Country Club which sampled from August to October, 2011. We selected the celluloytic bacteria from aerobic heterotrophic bacteria and identified 6 strains among ninety-six isolates by using 16S rDNA analysis. As a result, four isolates belonged to Firmicute group, two isolates belonged to Gamma-proteobacteria group and Actinobacteria group, respectively. We also analysed the cabon sources utilization patterns of six isolates. D-cellobiose, D-Fructose, D-Galactose, D-Mannose, DMelibiose, D-Psicose, Gentiobiose, Lactulose, L-Arabinose, L-Fucose, Turanose, α-D-Glucose, and α-D-lactose among 95 carbon sources are utilized by all six isolates.
