Isolation and characterization of IS1165, an insertion sequence of Leuconostoc mesenteroides subsp. cremoris and other lactic acid bacteria
1992
Johansen, E. | Kibenich, A.
We have cloned and characterized an insertion sequence from Leuconostoc mesenteroides subsp. cremoris strain DB1165. This element, designated IS1165, is 1553 bp, has imperfect inverted repeat ends, contains an open reading frame of 1236 bp, and is not related to any previously described insertion sequence. The copy number of IS1165 varies from 4 to 13 in L. mesenteroides subsp. cremoris strains allowing genetic fingerprinting of strains based on location and number of bands on hybridization. IS1165 or closely related elements have been detected by hybridization in L. lactis, L. oenos, Pediococcus sp., Lactobacillus helveticus, and Lb. casei but not in Lactococcus.
