(Submitter supplied) A strong promoter increases transcription of the genes of interest and enhances the production of various valuable substances. For a hyperthermophilic archaeon Thermococcus onnurineus NA1, which can produce H2 by carbon monoxide oxidation, we searched for a novel endogenous strong promoter by transcriptome analysis using high-throughput RNA sequencing. Based on the relative transcript abundance, we selected one promoter to encode a hypothetical gene, of which homologs were found only in several Thermococcales strains. more...

(Submitter supplied) Investigation of whole genome gene expression level changes in an Frh-deficient mutant, Frh overexpression mutant and TON_0282 deletion mutant, compared to the wild-type strain. In this study, as a first step to assess the role of the frhAGB-encoding hydrogenases and TON_0282 gene, we constructed three mutants by deleting each gene in a T. onnurineus NA1.

(Submitter supplied) Purpose: Compare the transcriptomes of T. paralvinellae using RNA-Seq gene expression analyses to understand the physiology of this organism when it is grown on different carbon sources, under optimal and hydrogen stress conditions. Methods: T. paralvinellae was grown in triplicate at with either 0.5% maltose or 0.5% tryptone to investigate its catabolic pathways when grown on a sugar and peptides, respectively. more...

(Submitter supplied) A hyperthermophilic archaeon Thermococcus onnurineus NA1 can grow and produce H2 on a variety of CO-containing feed stocks such as by-product gas generated from steel-mill process. In this study we applied a long-term adaptive evolution to enhance H2 productivity. Through serial transfer of cell cultures with carbon monoxide (CO) as an energy source, we observed physiological changes in cell density, CO consumption rate and H2 production rate. more...

(Submitter supplied) We show the transcriptomic landscape of the H2-producing archaeon Thermococcus onnurineus NA1 in response to different growth conditions using primary and whole transcriptome sequencing. We identified 1,082 purine-rich transcription initiation sites along with well-conserved TATA boxes, A-rich B recognition elements (BREs), and promoter proximal element (PPE) motifs in promoter regions, a high pyrimidine nucleotide content (T/C) at the −1 position, and Shine-Dalgarno (SD) motifs (GGDGRD) in 5' untranslated regions (5' UTRs). more...

(Submitter supplied) Previously, we reported that the TON_1525 (T55I) (designated as MC11) strain showed superior activity in CO oxidation than the wild-type strain. To understand the in vivo role of TON_1525 in this strain on CO-supplemented medium, transcriptome changes were investigated.

(Submitter supplied) The purpose of this experiment was to compare the transcriptomes of M. jannaschii using RNA-Seq gene expression analyses to understand the physiology of this organism when it is grown under H2-replete, H2-limited and H2-syntrophy conditions. The RNA-seq reads were mapped to both M. jannaschii and T. paralvinellae genomes using BBSplit from BBMap package. BBSplit is an aligner tool that bins sequencing reads by mapping to them multiple references simultaneously and separates the reads that map to multiple references to a special "ambiguous" file for each of them. more...

(Submitter supplied) 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. more...

(Submitter supplied) Insights into the Metabolism of Elemental Sulfur by the Hyperthermophilic Archaeon Pyrococcus furiosus: Characterization of a Coenzyme A-Dependent NAD(P)H Sulfur Oxidoreductase The hyperthermophilic archaeon Pyrococcus furiosus, uses carbohydrates as a carbon source and produces acetate, CO2 and H2 as end products. When S° is added to a growing culture, within 10 min the rate of H2 production rapidly decreases and H2S is detected. more...

(Submitter supplied) Glass slide, see protocol above. Protocol: Each of the known 2192 ORFs in P. furiosus were amplified individually by PCR. Primers were selected to produce full-length PCR products. In case of large ORFs >2 kb PCR primers were designed to yield a PCR product around 1 kb. Expected PCR products with high homology to more than one locus were replace by a 50-mer specific oligo. Oligos were purchased from MWG Biotech (High Point, NC) in a 96-well format. more...

(Submitter supplied) Background: Prokaryotes have relatively small genomes, densely-packed and apparently dominated by protein-encoding sequences. However, data now generated by high throughput RNA sequencing (RNA-seq) reveal surprisingly more-complex transcriptomes with many previously unrecognized and unanticipated non-coding small and antisense transcripts. To date, such studies have investigated primarily Bacteria. more...

(Submitter supplied) Methanococcus maripaludis is a methanogenic archaeon. Within its genome, there are two operons for membrane associated hydrogenases, eha and ehb. To investigate the regulation of ehb on the cell, an S40 mutant was constructed in such a way that a portion of the ehb operon was replaced by pac cassette in the wild type parental strain S2 (done by Whitman's group at the University of Georgia). Four samples of each strain were grown in batch culture. more...
