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.

Project description:Total RNAs were isolated from the thermophilic archaeon Sulfolobus acidocaldarius MW001 and subjected to Illumina sequencing. A differential gene expression analysis was performed to identify ncRNA in biofilm- associated cells and planktonically grown cells. Additionally, the small RNA subpopulation of the transcriptome was subjected to RNaseR digestion prior to Illumina sequencing. An abundant double-stranded RNA was identified.

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.

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.

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.

Project description:Sulfolobus acidocaldarius has been previously reported to grow on a broad range of sugars, but there is limited information on the ability of the organism to metabolize multiple sugars simultaneously. We report here the ability of S. acidocaldarius to utilize glucose and xylose simultaneously without di-auxie effect. The organism utilized a mixture of 1 g/L glucose and 1 g/L xylose with a growth rate of 0.079 h-1 compared to 0.074 h-1 and 0.22 h-1 when the organism was grown on xylose 2 g/L and 2 g/L glucose respectively as sole carbon sources. An increase in xylose concentration to 2 and 4 g/L in a medium containing 1 g/L glucose resulted in a growth rate of 0.082 and 0.085 h-1. However, increasing glucose concentration by 2 and 4 g/L when xylose concentration was maintained at 1 g/L decreased the growth rate to 0.062 and 0.052 h-1 respectively. S. acidocaldarius appeared to be utilizing the sugars at a rate roughly proportional to their concentration in the medium, resulting in complete utilization of these sugars at same time. The organism did not show preference for either glucose or xylose when it was grown on both sugars. Similar results were obtained with a combination of glucose, arabinose and galactose. These observations strongly suggest that S. acidocaldarius does not regulate utilization of the sugars tested herein using carbon catabolite repression (CCR) commonly found in most bacteria. The mechanism by which the organism utilized a mixture of sugar is yet to be elucidated. However, we were able to identify genes encoding for the putative glucose ABC transporters; but the putative xylose transporter was not identified.
