Expression Profile of R. capsulatus under heat and cold stress

Project description:The effects of temperature stress on transcriptome of purple non sulfur bacterium R. capsulatus were investigated by comparing expression profiles under optimum hydrogen production condition (30M-BM-0C), heat (42M-BM-0C) and cold (4M-BM-0C) stress conditions. Bacteria were grown anaerobically under continuous illumination (200 W/m2) in 150 ml volume photobioreactors at 30M-BM-0C for 48 hours. Then cold stress (4M-BM-0C) and heat stress (42M-BM-0C) were applied in parallel. For microarray analysis, RNA samples from 1.5x109 cells were collected after 2 hours and 6 hours of stress applications. A microarray chip for Rhodobacter capsulatus was not commercially available. For that reason, a GeneChipM-BM-. array was custom designed and manufactured by Affymetrix, Santa Clara, California. The nucleotide sequence of the bacterium is available in GenBank with the accession numbers CP001312 for the chromosome and CP001313 for the plasmid pRCB133. The feature size of the antisense DNA array was 11 micron and the format was 100-3660. A total of 4,052 probe sets for open reading frames (ORFs) and 200 intergenic sequences with longer than 300bp were placed on the microarray. The cDNA synthesis, labeling, and hybridization protocols were performed according to the Affymetrix Expression Analysis Technical Manual given for prokaryotic samples

Expression profile of R. capsulatus by entering light after a dark period; and by high light intensity

Project description:The effects of low and high light intensities on transcriptome of purple non sulfur bacterium R. capsulatus were investigated by comparing expression profiles of dark and low light intensity (2000 lux), and by comparing high light intensity (10,000 lux) with low light intensity (2000 lux).

Expression Profile of R. Capsulatus on different nitrogen sources and different concentrations of acetate

Project description:The influence of different nitrogen sources on transcriptome of Purple non sulfur bacterium R. Capsulatus was investigated by comparing expression profile on 5mM ammonium chloride and 2 mM glutamate. Carbon source was 40mM acetate on both conditions. To study the effect of different acetate concentrations, 40mM and 80mM acetate were used with 2 mM glutamate as nitrogen source. Bacteria were grown anaerobically under continuous illumination (200 W/m2) in 150 ml volume photobioreactors at 30M-BM-0C. For microarray analysis, RNA samples were collected after 16h of inoculation from 1.5x109 cells. A microarray chip for Rhodobacter capsulatus was not commercially available. For that reason, a GeneChipM-BM-. array was custom designed and manufactured by Affymetrix, Santa Clara, California. The nucleotide sequence of the bacterium is available in GenBank with the accession numbers CP001312 for the chromosome and CP001313 for the plasmid pRCB133. The feature size of the antisense DNA array was 11 micron and the format was 100-3660.

Transcriptomic study of hydrogen sulfide toxicity in Methylococcus capsulatus

Project description:Stress response of Methylococcus capsulatus str.Bath toward hydrogen sulfide (H2S) was investigated via physiological study and transcriptomic profiling. M. capsulatus (Bath) can grow and tolerate up to 0.75%vol H2S in headspace. Vast change in pH suggests biological relevant sulfide oxidation. Dozens of H2S-sensitive genes were identified from comparison of cell transcriptome in different H2S concentrations. Mc sulfide quinone reductase (SQR) and persulfide dioxygenase were found to be active during sulfide detoxification. Moreover, xoxF, a novel lanthanide(Ln)-dependent methanol dehydrogenase (MDH) was overexpressed in H2S while mxaF, a calcium-dependent MDH, was down-regulated, and such MDH switch phenomenon is also well known to be induced by addition of lanthanide via an as-yet-unknown mechanism. Activities in quorum sensing and RND efflux pump also suggest their role in sulfide detoxification, and might provide insight on the xoxF/mxaF switch mechanism.

Rhodobacter capsulatus SB1003 under singlet oxygen stress

Project description:Global transcriptome analyses at growth before and after 10 min of photooxidative stress were applied to monitor stress dependent gene expression in the alpha-proteobacterium Rhodobacter capsulatus. Transcriptome profiles of pigmented cultures with high aeration were monitored before and after the onset of singlet oxygen stress.

Not just an alternative nitrogenase: The Fe-nitrogenase system belongs to the NifA regulon in Rhodobacter capsulatus

Project description:The diazotrophic bacterium Rhodobacter capsulatus synthesizes a molybdenum nitrogenase and an alternative iron-only nitrogenase, enabling growth with molecular dinitrogen as sole nitrogen source. Regulation of nitrogen fixation was analyzed by proteome profiling of wild-type and mutant strains lacking the transcriptional regulators NifA, AnfA, and MopAB.
