This note represents a grouping of identical Lactococcus lactis sequences from various subspecies and strains. These sequences are represented as Group 2. The other Lactococcus lactis sequences are in Groups 1, 3, and 4. In all four groups, there are 15 sequences total. The full names and GenBank accession numbers of Lactococcus lactis sequences classified in Group 2 are as follows: Organism name GenBank AC# Lactococcus lactis sbsp. lactis biovar diacetylactis strain IL1403 AF375553 Lactococcus lactis sbbp. lactis biovar diacetylactis strain IL986 AF375562 Lactococcus lactis sbsp. lactis strain CNRZ188 AF375565 Lactococcus lactis sbsp. lactis biovar diacetylactis strain CNRZ124 AF375566 Table 1. Full names and Genbank accession numbers of sequences in Group 2. Table 2 (shown below) shows the differences between the groups of sequences. All sequences are 310 bp long.
