Abstract:
:The relative isolation and unique physical properties of the Savusavu Hot Springs in Fiji may yield unique thermophiles. This study was conducted to determine the presence of aerobic thermophilic bacteria in these hot springs. A total of 104 thermophilic bacterial isolates were characterized and using Thermus and Bacillus strains as controls, 58% of the isolates were identified as Anoxybacillus flavithermus, 19% as Geobacillus stearothermophilus/Bacillus licheniformis, 10% as Thermus sp. TG153 and 10% as Thermus sp. TG206. Four isolates were unique in their molecular patterns suggesting there may be novel bacteria in the Savusavu hot springs.
