Project description:A hyperthermophilic archaeon Thermococcus kodakarensis can grow in a wide range of temperatures from 60°C to 93°C, optimally at 85°C. To screen the genes that being specifically expressed at lowest growth temperature, 60°C, we investigated the transcriptional profilings of T. kodakarensis grown at 60˚C by comparing with those grown at 85°C.
Project description:This SuperSeries is composed of the following subset Series: GSE28549: Anaerobic Oxidation of Benzene by the Hyperthermophilic Archaeon Ferroglobus placidus (Phenol vs. Benzoate) GSE30798: Anaerobic Oxidation of Benzene by the Hyperthermophilic Archaeon Ferroglobus placidus (Benzene vs. Acetate) GSE30799: Anaerobic Oxidation of Benzene by the Hyperthermophilic Archaeon Ferroglobus placidus (Benzene vs. Phenol) GSE30801: Anaerobic Oxidation of Benzene by the Hyperthermophilic Archaeon Ferroglobus placidus (Benzene vs. Benzoate) Refer to individual Series

To screen the genes that being specifically expressed at lowest growth temperature, 60°C, we investigated the transcriptional profilings of T. kodakarensis grown at 60ËC by comparing with those grown at 85°C. One-condition experiment, KU216 grown at optimal growth temperature, 85°C vs. KU216 grown at lowest growth temperature, 60°C. Technical replicates: 2 KU216 grown at 60°C, independently measured. One replicate per array.
Project description:This SuperSeries is composed of the following subset Series: GSE26421: Expression analysis of benzoate degradation in the hyperthermophilic archaeon Ferroglobus placidus GSE26423: Expression analysis of phenol degradation in the hyperthermophilic archaeon Ferroglobus placidus Refer to individual Series
Project description:Hyperthermophilic archeaon, Thermococcus onnurineus NA1 has known as a strict anaerobe. To date, a few of studies have been reported that strict anaerobe can grow using oxygen. However, the research of the growth enhancement of strict anaerobic archaeon belonging to the order of Thermococcales using the oxygen, in which has never been reported so far. In this study, we showed that the growth of T. onnurineus NA1 strain increased under various oxygen concentrations and we observed that oxygen was decreased in the headspace during the growth of cell. Genome-wide transcriptomic analysis was carried out to evaluate alterations in gene expression induced by O2 and to explain the physiological effects of oxidative stress on the growth of T. onnurineus NA1.
