Nepenthes spp. is a tropical pitcher plant that has a pitcher containing fluid as a unique habitat for microorganisms. Until recently, only few reports on the diversity of microbes living in the pitcher fluid. The purpose of this study was to compare bacterial community of several pitcher plants species. We collected fluid samples from five species of pitcher plants, i.e. Nepenthes ampullaria, N. gymnamphora, N. mirabilis, N rafflessiana, and N. reinwardliana. The levels of the bacterial community diversity of pitcher plants fluid samples and two leaf samples were analyzed employing amplified ribosomal DNA restriction analysis (ARDRA). The phylotype richness and frequency distribution or relative abundance (evenness) of the samples were investigated using Shannon-Weiner diversity indices. ARDRA analysis showed that pitcher plant fluid was found to be inhabited with a complex bacterial community with fluid sample of N. ampullaria TJI-2 from Tanjung Selor, East Kalimantan, has the highest diversity index. ARDRA results showed that bacteria occupied the fluid were very diverse and scattered among the pitcher plants species. There was no correlation of bacterial community between the species itself nor the location where the plant is grown.
