Sample GSM4498574 Query DataSets for GSM4498574
Status Public on Sep 01, 2020
Title Faecalicatena contorta 588 Galactose 2
Sample type SRA
 
Source name Bacterial Total RNA
Organism Faecalicatena contorta
Characteristics strain: 588
carbon source: Galactose
Treatment protocol Cells were centrifuged to remove negatively charged polysaccharides and cell pellets were treated with two volumes of RNA Protect (Qiagen) of the original culture volume then frozen at -80C until RNA was extracted
Growth protocol Strains were grown to mid-log on 5 mg/ml seaweed polysaccharides (carrageenan, agarose and/or poprhyran respective to strain) or galactose as a sole carbon source in vitro.
Extracted molecule total RNA
Extraction protocol Qiagen Rneasy kit and rRNA depleted with Microbe Express Kit (Thermo Fisher)
RNA libraries were prepared for sequencing using standard Illumina protocols
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NextSeq 500
 
Description Fcontorta588 DEseq
126121_ATTCAGAA-ATAGAGGC_S14_L004_R1_001
Data processing Data was analyzed using Arraystar software (DNASTAR, Inc.)
DEseq2 normalization with default parameters
Gene expression in seaweed polysaccharides was compared to gene expression in galactose reference
Genes with significant up- or down-regulation were determined by the following criteria: genes with an average fold-change >10-fold and with both biological replicates with a normalized expression level >1%
Genome_build: B. thetaiotaomicron 3731 is NZ_CVOY00000000.1 (B. xylanisolvens 18002P, F contorta 548 and 588 are de novo assemblies)
Supplementary_files_format_and_content: xslx files include DEseq2 values for each sample
