The profiles of transcripts from the planktonic cells and biofilm cells of V. vulnificus were compared by using a V. vulnificus whole-genome microarray Overall design: Two-condition experiment, planktonic cells vs. biofilm cells. Biological replicates: 3 control, 3 experimental, independently grown and harvested. One replicate per array. For transcriptome analysis, the V. vulnificus whole genome TwinChip, manufactured and kindly provided by the 21C Frontier Microbial Genomics and Applications Center (Daejeon, South Korea), was used.
