Characterization of Leuconostoc Isolates from Commercial Mixed Strain Mesophilic Starter Cultures

Genomic Characterization of Dairy Associated Leuconostoc Species and Diversity of Leuconostocs in Undefined Mixed Mesophilic Starter Cultures

Undefined mesophilic mixed (DL-type) starter cultures are composed of predominantly Lactococcus lactis subspecies and 1-10% Leuconostoc spp. The composition of the Leuconostoc population in the starter culture ultimately affects the characteristics and the quality of the final product. The scientific basis for the taxonomy of dairy relevant leuconostocs can be traced back 50 years, and no docum...

Genome Sequence of Leuconostoc mesenteroides subsp. cremoris Strain T26, Isolated from Mesophilic Undefined Cheese Starter

Leuconostoc is the main group of heterofermentative bacteria found in mesophilic dairy starters. They grow in close symbiosis with the Lactococcus population and are able to degrade citrate. Here we present a draft genome sequence of Leuconostoc mesenteroides subsp. cremoris strain T26.

Characterization of Ornithobacterium rhinotracheale Isolates from Commercial Chickens

Characterization of a Leuconostoc bacteriophage infecting flavor producers of cheese starter cultures.

Dairy siphovirus φLmd1, which infects starter culture isolate Leuconostoc mesenteroides subsp. dextranicum A1, showed resistance to pasteurization and was able to grow on 3 of the 4 commercial starter cultures tested. Its 26,201-bp genome was similar to that of Leuconostoc phage of vegetable origin but not to those of dairy phages infecting Lactococcus.

Genome Sequences of Two Leuconostoc pseudomesenteroides Strains Isolated from Danish Dairy Starter Cultures

The lactic acid bacterium Leuconostoc pseudomesenteroides can be found in mesophilic cheese starters, where it produces aromatic compounds from, e.g., citrate. Here, we present the draft genome sequences of two L. pseudomesenteroides strains isolated from traditional Danish cheese starters.
