Sample GSM5013455 Query DataSets for GSM5013455
Status Public on Jan 12, 2021
Title cells from 115 h old biofilm rep 4
Sample type SRA
 
Source name Bacterial biofilm cells
Organism Pseudomonas fragi
Characteristics strain: 1793
tissue: Bacterial biofilm cells
Growth protocol P. fragi biofilms were grown on surface sterilized beef cuts kept at 10 P. fragi biofilms were grown on surface sterilized beef cuts kept at 10 ͦC under aerobic conditions
Extracted molecule total RNA
Extraction protocol RNA was extracted with the RNeasy minikit (Qiagen, MD, cat no-74104) using the protocol for disruption of bacteria grown on solid media,
RNA libraries were prepared for sequencing using standard Illumina protocols
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2500
 
Data processing Galaxy platform was used for data analysis. Trimming of the reads were not due to high quality of data.
The reads were mapped to the P. fragi 1793 reference genome (Gene bank accession no NQKS00000000) with the Burrows-Wheeler Aligner (version 0.7.17) using the BWA-MEM algorithm. The mapped reads, which were in BAM format, were visualised using Jbrowse genome browser (version 1.16.4) to determine the efficiency of mapping. Mapped reads were used in subsequent analyses.
To estimate the number of genes overlapping with each gene in the reference genome, the SAM/BAM to count matrix of Galaxy was used.
Differential expression was examined using the Voom tool (Galaxy Version 0.28) ,
The gene expression of P. fragi in the three stages of the biofilm: (Initiation vs Maturation), (Initiation vs Dispersal), and (Maturation vs Dispersal) were compared pairwise using the DEGUST tool (http://degust.erc.monash.edu/).
