Sample GSM2792949 Query DataSets for GSM2792949
Status Public on Oct 01, 2017
Title HI broth microaerophilic early stat.
Sample type SRA
 
Source name monoculture
Organism Campylobacter jejuni
Characteristics strain: 81116
genotype: wild type
treatment: microaerophilic (5% Oxygen)
Growth protocol Campylobacter precultures were diluted to an OD550 of 0.05 and grown microaerophilic (5% O2, 8% CO2, 8% H2) in HI medium, or HI medium + 25mM serine, or HI medium + 25mM aspartate to mid-log phase (6hr) or early stationary phase (12hr).
Extracted molecule total RNA
Extraction protocol Total RNA was extracted from cultures with the RNA-BeeTM kit (Tel-Test, Inc) according to the manufacturer’s specifications. . Subsequently, RNA was treated with RNAse-free DNAseI (Thermo) according to the instructions of the manufacturer.
Ribozero Magnetic Kit for-gram negative bacteria (Illumina) following manufacturer’s instructions using following the 5ug RNA procedure and option 1 (Ethanol precipitation), except using 1/8th reaction volumes/amounts. Illumina libraries were prepared using the KAPA stranded RNA-seq kit (Kapa Biosystems, Wilmington, MA), following manufacturer’s instructions to produce ~300bp fragments. Standard desalting TruSeq LT primers were ordered from Integrated DNA Technologies (Coralville, IA) and used at 50-100nM final concentration based on starting RNA amount. The PCR step was reduced to 6 cycles. Libraries were quantified using the KAPA Library Quantification Kit (Kapa), except with 10 µl volume and 90 sec annealing/extension PCR. Libraries were pooled and normalized to 4 nM. Pooled libraries were re-quantified by ddPCR on a QX200 system (Bio-Rad), using the Illumina TruSeq ddPCR Library Quantification Kit and following manufacturer’s protocols. The libraries were sequenced in two 2x76bp paired end v3 runs on a MiSeq instrument (Illumina) at 13.5 pM, following manufacturer's protocols.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina MiSeq
 
Data processing Illumina MiSeq Real-time analysis (RTA) used for basecalling.
Sequenced reads were trimmed for low-quality sequence, then mapped to CP000814 using bowtie v1.1.2 within Geneious v9.1 parameters -n 2 -l 28 -q -p 4 --best --strata
Geneious v9 software was used to calculate the normalized transcripts per million (TPM) and to compare expression levels between the control growth condition (microaerophilic) and experimental conditions (oxygen limited+ nitrate, and oxygen limited).
