The bacterial community of water stream, soil and guano in Gossi cave was examined by using PCR amplified the 16S rDNA-denaturing gradient gel electrophoyesis (DGGE). In this study, the genetic diversity and the similarity of bacterial community between open area and non - open area toy cave tour were investigated, and the seasonable variation pattern was compared each other. DGGE is attractive technique, as it sepayate same length dsDNA according to sequence variation typical 16S rDNA genes. The diversity and similarity of bacterial community in cave was analyzed by GC341f and PRUN518r primer sets foy amplification of V3 region of eubacteria 16S rDNA. The specific DGGE band profile of the cave water gives the possibility that the specific bacterial cell can be adapting to the specific cave environment and living in the cave. The DGGE band profiles of all samples with guano were compared and analyzed by image analyzer, in which mutual band profile was compared to be and the band intensity of guano was the highest. From these result, it is thought that the guano was main nutrient source and influenced on the community structure of the cave environment where is nutritionally limited. Pseudomonas sp. NZ060, Pseudomonas pseudoalcaligenes, uncultured Variovorax sp. and soli bacterium NS7 were identified to be on some sample from analysing DNA sequence of some DGGE band.
