- Abstract
- Dairy propionibacteria, and especially Propionibaclerium freudenreichii subsp. shermanii, are important in the food industry and biotechnology. Only a few investigations have focused on the complex physiology of this remarkable bacterium, while the physiology of dairy lactic acid bacteria has been extensively studied over the past decades. Here we report the progress of our whole genome sequencing project: 93% of the P. shermanii genome was assembled in 426 contigs with low overall redundancy. Our annotation strategy overlaps the sequence finishing step, thus improving it. Annotation of the incomplete genome is performed using ContigBrowser, a bioinformatic tool allowing data management, developed in our laboratory. This resulted in the detection of 2611 putative proteins (data May 2003). Our tool allows an expert annotation by manual verification and curation of functional protein categories after automatic assignment. Our genomic sequence analysis, combined with the already developed physiological, proteomic and metabolomic approaches, will allow researchers to explore the significant potentialities of dairy propionibacteria by providing a comprehensive view of the enzymes and metabolic pathways. This knowledge will allow researchers to explore more effective strategies to enhance the utility of this organism in manufacturing procedures or current industrial processes.
