Bacillus subtilis is the best-characterized member of the Gram-positive bacteria. Its genome of 4,214,810 base pairs comprises 4,100 protein-coding genes. Of these protein-coding genes, 53% are represented once, while a quarter of the genome corresponds to several gene families that have been greatly expanded by gene duplication, the largest family(More)
Numerous prokaryote genomes contain structures known as clustered regularly interspaced short palindromic repeats (CRISPRs), composed of 25-50 bp repeats separated by unique sequence spacers of similar length. CRISPR structures are found in the vicinity of four genes named cas1 to cas4. In silico analysis revealed another cluster of three genes associated(More)
BACKGROUND Bacillus licheniformis is a Gram-positive, spore-forming soil bacterium that is used in the biotechnology industry to manufacture enzymes, antibiotics, biochemicals and consumer products. This species is closely related to the well studied model organism Bacillus subtilis, and produces an assortment of extracellular enzymes that may contribute to(More)
Streptococcus thermophilus is a major dairy starter used for the manufacture of yoghurt and cheese. The access to three genome sequences, comparative genomics and multilocus sequencing analyses suggests that this species recently emerged and is still undergoing a process of regressive evolution towards a specialised bacterium for growth in milk. Notably, S.(More)
This review summarizes a collection of lactic acid bacteria that are now undergoing genomic sequencing and analysis. Summaries are presented on twenty different species, with each overview discussing the organisms fundamental and practical significance, environmental habitat, and its role in fermentation, bioprocessing, or probiotics. For those projects(More)
Identification of short genes that encode peptides of fewer than 60 aa is challenging, both experimentally and in silico. As a consequence, the universe of these short coding sequences (CDSs) remains largely unknown, although some are acknowledged to play important roles in cell-cell communication, particularly in Gram-positive bacteria. This paper reports(More)
BACKGROUND A challenging goal in biology is to understand how the principal cellular functions are integrated so that cells achieve viability and optimal fitness in a wide range of nutritional conditions. METHODOLOGY/PRINCIPAL FINDINGS We report here a tight link between glycolysis and DNA synthesis. The link, discovered during an analysis of suppressors(More)
Frankia strain R43 is a nitrogen-fixing and hydrogen-producing symbiotic actinobacterium that was isolated from nodules of Casuarina cunninghamiana but infects only Elaeagnaceae. This communication reports the genome of the strain R43 and provides insights into the microbe genomics and physiological potentials.
We constructed a PCR map of the 150 kb spoIIIC-pheA region of the Bacillus subtilis chromosome. It was established using known sequences of the spoIIIC, blt, aadK, sacC, spoVB and pheA loci and eight random sequence tags. The tags were generated using PFGE-purified DNA of yeast artificial chromosome (YAC) 11-17 from the yeast clone which carries the major(More)
Within the framework of the European project to sequence the whole Bacillus subtilis 168 genome, a 23911 bp long chromosomal DNA fragment located around 233 degrees on the B. subtilis genetic map was cloned and sequenced. From the generated sequencing data and the results of the homology search, the primary structure of this region was determined. In(More)
