This study describes the fluid chemical compositions and related microbial diversity in geothermal systems of Taiwan. The fluid samples were collected from several geothermal springs located in northern and southern Taiwan. The pH values of the fluids showed diverse character of the geothermal systems, some are acidic in nature while few showed alkaline in nature. The fluids also contain high arsenic concentrations with As(III) as the dominant species. Yang-Ming-Shan and Beitou hot springs in northern Taiwan were characterized by sulfur spring type (contains H-SO 4). The 16S rRNA gene sequence of microbial community indicated the presence of thiosulfate-oxidizing, alkaliphilic, psychrotolerant and chemo-organoheterotrophy bacterium such as Limnobacter thiooxidans, Clostridium sulfidigenes and Des-ulfovibrio psychrotolerans, respectively.
