Genome sequence of the phage clP1, which infects the beer spoilage bacterium Pediococcus damnosus
Abstract
Pediococcus damnosus (P. damnosus) bacteriophage (phage) clP1 is a novel virulent phage isolated from a municipal sewage sample collected in Southern Ireland. This phage infects the beer spoilage strain P. damnosus P82 which was isolated from German breweries. Sequencing of the phage has revealed a linear double stranded DNA genome of 38,013 base pairs (bp) with an overall GC content of 47.6%. Fifty seven open reading frames (ORFs) were identified of which 30 showed homology to previously sequenced proteins, and as a consequence 20 of these were assigned predicted functions. The majority of genes displayed homology with genes from the Lactobacillus plantarum phage phiJL-1. All genes were located on the same coding strand and in the same orientation. Morphological characterisation placed phage clP1 as a member of the Siphoviridae family with an isometric head (59 nm diameter) and non-contractile tail (length 175 nm; diameter 10nm. Interestingly, the phage clP1 genome was found to share very limited identity with other phage genome sequences in the database, and was hence considered unique. This was highlighted by the genome organisation which differed slightly to the consensus pattern of genomic organisation usually found in Sip...Continue Reading

Bacteriophage: Phage Therapy
Phage therapy uses bacterial viruses (bacteriophages) to treat bacterial infections and is widely being recognized as an alternative to antibiotics. Here is the latest research.
Bacterial Cell Wall Structure
Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids. Here is the latest research on bacterial cell wall structures.
