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...

Tellurite exerts a deleterious effect on a number of small molecules containing sulfur moieties that have a recognized role in cellular oxidative stress. Because cysteine is involved in the biosynthesis of glutathione and other sulfur-containing compounds, we investigated the expression of Geobacillus stearothermophilus V cysteine-related genes cobA, cysK, and iscS and Escherichia coli cysteine...

Pyridoxal kinase encoded by pdxK gene, is the important key enzyme in salvage pathway of vitamin B6 biosynthesis. The catalyzes phosphorylation 5′ alcohol groups free form into their 5′-phosphate forms that requires metal ion and ATP. have been reported many organisms except thermophilic bacterium. Therefore, this study aimed to clone, express characterize pyridoxal Geobacillus sp. H6a isolated...
