(Submitter supplied) Genomic rearrangement, often driven by insertion sequence (IS) elements, is one of the major processes in the evolution of prokaryotes. Sequence analysis of 16S rRNA of Lactobacillus helveticus, an organism that evolved in a dairy environment and Lactobacillus acidiophilus an organism that evolved associated with the gastrointestinal tract (GIT) demonstrated 98.4% identity suggesting that they divergently evolved from a common ancestor. more...

(Submitter supplied) L. helveticus is used to modulate cheese flavor and as a starter organism in certain cheese varieties. Our group has compiled a draft (4x) sequence for the 2.4 Mb genome of an industrial strain L. helveticus CNRZ32. The primary aim was to investigate expression of 168 completely sequenced genes during growth in milk and MRS medium using microarrays. Oligonucleotide probes against each of the completely sequenced genes were compiled on maskless photolithography-based DNA microarrays. more...
