Transcriptional Response of the thermoacidophilic Archaeon Sulfolobus acidocaldarius to solvent stress exemplified by 1-butanol exposure

Project description:To study the cellular global response of the thermoacidophilic Archaeon Sulfolobus acidocaldarius upon solvent exposure we performed transcriptome comparing the response of planktonic and biofilm cells in absence and presence 1-butanol. S. acidocaldarius was grown in Petri dishes (static incubation) in the absence and presence of 0.5% and 1% (v/v) 1-butanol at 76°C for four days. Planktonic and biofilm cells were harvested and the transcriptional response towards 1-butanol was analysed via RNA-seq. In detail:Biofilm and planktonic cell samples (supernatant after static incubation) were generated in Petri dishes (92 x 16 mm, Polystyrene, without cams, Sarstedt) as described before. Cells grown under six different conditions, including Biofilm-Control (BF0), Biofilm-0.5% (v/v) 1-Butanol (BF05), Biofilm-1% (v/v) 1-Butanol (BF1), Planktonic-Control (PL0), Planktonic-0.5% (v/v) 1-Butanol (PL05), Planktonic-1% (v/v) 1-Butanol (PL1), were seperated, harvested by centrifugation (10 min, 5,000 x g, 4 °C) and immediately frozen at -70 °C. Isolation of cells was performed in triplicates with ten technical replicas each. Samples were pooled to obtain sufficient cell mass for further processing. RNA was isolated using Trizol (Thermo Fisher Scientific). In accordance, sequencing libraries were prepared via Illumina TruSeq stranded mRNA using Ribozero for RNA depletion. Sequencing was performed on a MiSeq instrument (Illumina, San Diego, California, USA) using v3 chemistry with a read length of 2x76 nt.

Response of the thermoacidophilic Archaeon Sulfolobus acidocaldarius to solvent stress

Project description:In this study, we used S. acidocaldarius adapted to two extremes, low pH and high temperature, to study its tolerance and robustness as well as its global cellular response towards organic solvents exemplified by 1-butanol. We were able to identify biofilm formation as primary cellular response to 1-butanol.

Cellular stress response of Sulfolobus acidocaldarius to nutrient limitation

Project description:This study provides novel insights into archaeal stress response. The effect of nutrient limitation on the thermoacidophilic crenarchaeon Sulfolobus acidocaldarius was monitored over time on transcriptomic, proteomic and metabolic level. To our knowledge, this linkage of transcriptome, proteome, metabolome analysis makes this study a pioneer study to elucidate cellular stress response triggered by nutrient limitation. We further connect previously identified pH and salt stress responsive genes (1) with genes regulated in starvation and suggest that they constitute the core of stress responsive genes active under multiple stress sources.

Sulfolobus acidocaldarius phosphoproteome

Project description:Shotgun phosphoproteome of Sulfolobus acidocaldarius using PAciFIC technique. Briefly, proteins were denatured, alkylated, trypsine digestion, SCX separation Fractionated peptides were analysed on Bruker HCTultra. Data processing and bioinformatics: data from mass spectrometry were then extracted to mgf format using Bruker Data Analysis V4.0 with a MRM script, these were then were searched against the Sulfolobus acidocaldarius database (containing 2223 proteins) downloaded from NCBI in March 2010 using Phenyx V 2.6 (Genebio, Geneva). The searches were performed using parameters as follows: carbamidomethylation of cysteine (fixed modification), oxidation of methionine (variation), and phosphorylation of serine, tyrosine, threonine (variation), trypsin with 2 missed cleavages. Furthermore, other parameters such as parent, MS/MS, tolerances were set at 2.0 and 0.8 Da, respectively, whilst minimum peptide length, z-score, p-value and AC score were set at 5, 5.5, 10-5, and 5.5 respectively.

Transcriptome analysis of Sulfolobus acidocaldarius DSM 639 under sugar-free and sugar-rich conditions

Project description:Sulfolobus acidocaldarius is an obligate aerobe that grows in hot and acidic environments. S. acidocaldarius have been reported to grow on a variety of organic compounds as carbon and energy sources. However, little is known about systemic elucidation of carbon utilization for biomass formation and energy metabolism in S. acidocaldarius. In this analysis, the effect of glucose on genome-wide transcriptional profiling in S. acidocaldarius DSM 639 was investigated by RNA-Seq technology.
