Our expeditions to Tangkuban Perahu, West Java aimed to obtain archaealstrains from the solfatara fields located in Domas crater. From the samples, we intended to culture <em>Thermoplasma</em> species growing around 55 °C below pH 2, which until now have not yet been fully characterized. We collected five samples from mud holes with temperatures from 52 °C to 57 °C and pH below 2. In serial cultures of up to 8 transfers in Freundt’s medium we grew tetraetherlipid synthesizing <em>Thermoplasma</em> species as documented by phase contrast microscope. Total membrane lipid extracts were analysed by thin layer chromatography; the pattern matched total lipid extracts from <em>Thermoplasma acidophilum</em> DSM 1728 membranes. For confirmation, 16S rDNA identification performing PCR and sequencing were carried-out. Analysis using BLAST showed <em>T. acidophilum</em> identities as the highest similarity of 99%, followed by <em>T. volcanium,</em> also with99% similarity (ANKF776908 and ANKF776909). This is the first report of culturing cell-wall-less thermoacidophilicarchaea,in particular <em>Thermoplasma </em>species in Indonesian laboratories.</p> ER -
