Abstract
ABSTRACTLactobacillus helveticus is a lactic acid bacterium widely used in cheese-making and for the production of bioactive peptides from milk proteins. Here, we describe the draft genome sequence and annotation of L. helveticus strain Lh 12 isolated from natural whey starter used in the production of Grana Padano cheese.
Highlights
Lactobacillus helveticus is a lactic acid bacterium widely used in cheesemaking and for the production of bioactive peptides from milk proteins
Different strains of L. helveticus were analyzed for genes involved in the proteolytic system and amino acid catabolism [1]
A total of 2,327 genes were predicted by annotating the genome with both the NCBI Prokaryotic Genome Automatic Annotation Pipeline (PGAP) and the Rapid Annotations using Subsystems Technology (RAST) annotation server [7, 8]
Summary
Lactobacillus helveticus is a lactic acid bacterium widely used in cheesemaking and for the production of bioactive peptides from milk proteins. Differences in the biotype composition of NWS, which distinguish natural from selected cultures, are modulated by the incubation conditions of the drained whey, in strict synergy with small variations in the applied dairy technology [3, 5]. The interest in these undefined complex starter cultures is growing because of their low vulnerability to bacteriophage attack and because they represent a source for the isolation of new dairy strains with interesting functional characteristics [6].
