Citrobacter freundii

The Sanger Institute has been funded by the Wellcome Trust to sequence the genome of Citrobacter freundii ballerup 7851.

The DNA sequence of Citrobacter freundii ballerup 7851 was obtained by 454 FLX pyrosequencing, assembled using the 454/Roche Newbler assembly program.

Published Genome Data

357 contigs (N50 contig size 60,237 bp) were obtained from 410,057 sequence reads with an average read length of 177 bp, to give a total sequence length of 4,904,659 bp. The data are available in the European Nucleotide Archive with accession ERA000106.
